http://bitcoin-analytics.com offers realtime charts for both order books and actual trades.

The system consolidates data to get the big picture:

1) It consolidates small trades in time, so you can see the how a particular trade moves the resulting "real" execution price.  

2) It consolidates small orders in orderbooks - so you can see the resulting "real" offer

3) It visualizes time between trades - so you can estimate how long will it take for a small exchange to execute your trade

4) Trade prices, order books and time between trades are consolidated between exchanges, so you can see, for example, the best execution price for a block trade of 10000 BTC across all USD exchanges.

All data are separated into "bid" and "ask" sides to provide more details.

Charts are adjusted for desired trade volume when it makes sense. Let you, for example,  want to trade 1000 BTC. Then price impact of one order of 20 BTC is small. However, the price impact of 100 orders 20 BTC each is large. If you want to trade a smaller amount, say 5 BTC, then small orders have a bigger impact.

The system takes this effect into account - so 3 of the 5 charts for each exchange can be adjusted for trades of 10, 100, 1000, 10000 or 100000 BTC. We figured out that this granularity is enough. Finer adjustments don't provide with better insights as charts weighted for 10 and 15 BTC are similar. However, 10 and 1000 differ a lot.

You can read more about how our charts are calculated and how they can help taking trade decisions on 'Why' tab and its sub-tabs.

Consolidated view adjusted for volume of 1000 BTC is free. Full access requires a subscription for 0.3 BTC a month or 0.5 BTC for two months. You can enable subscription for just 24h for 0.05 BTC.

My co-founder and I believe that micro-payments are the only fair business model. We wanted  0.1 BTC or less initially, but taking in account small potential user base, that won't be enough to buy us a pizza and coke off the earnings.

Bitcoin enforces financial freedom, and we think that affordable micro-payments without government interference are the key to large scale Bitcoin success. Asking for donations is a manifestation of weakness - it would mean we don't believe that our own product is useful for other people and that most of our clients will reward us voluntarily. Advertisements would mean that our visitors pay indirectly, by being conditioned into buying other goods and services and by disclosing their private habits to advertisement agencies. Conditioning and violation of privacy are against freedom so they are against Bitcoin so they are bad.

Seemingly free services always have hidden cost. For example, welfare and pensions mean that you rob your own children, as they will have to pay for them in the future. We want our visitors to pay directly and voluntarily, without hidden costs of any kind. If you only use a free part of our service - you don't pay.

You can still help us by spreading the word - use 'Social' tab to like, tweet, reddit, digg us. We are proud to be a part of Bitcoin economy - so help it grow. We plan to add more gadgets to the tab over time.  

But if you find our work worthwhile - think of your subscription fee as buying us a slice of pizza and a coke every month to encourage us, so we can innovate freely and don't have to work for corporations or be tiny parts in state bureaucracy machines. There are not many Bitcoin users yet, we won't buy ourselves yachts and mansions - we only want feel the support and excitement of doing something that brings mankind closer to the free Bitcoin-based society.

Here is what you get with subscription:

Charts for today for btc-e and 100 BTC. You can also see all volume and exchange selectors enabled:

A pattern in orderboooks on cryptox, probably caused by trading bots constantly changing their order price:

Sparse activity on btcex. It took 16 hours to sell 100 BTC there, but buying activity of liquidity demanders is stronger:

Bitcoin Analytics now has "Arbitrage" tab.

The table displays arbitrage opportunities for lots of 10, 100, 1k, 10k and 100k BTC between different USD markets.

The table looks similar to http://nyse-group.de/bitcoin-arbitrage and other existing tables, but it has something different under the hood:

1. It doesn't display an opportunity if there's too little volume offered at a pair of exchanges.

You can see our arbitrage table shrinking as you increase the volume. For example, only 3 exchanges have 10k BTC in their order books: btceUSD, cryptoxUSD and mtgoxUSD.  

2. It displays market order execution prices for corresponding volume instead of best prices.

In most cases, very little volume is offered at the best price - so if MtGox ticker says 5.3, it doesn't mean that you can buy or sell 1000 coins at that price. Our arbitrage
calculator accounts for that by going deeper in the orderbook than best price and displaying you the real volume weighted average price between several orderbook entries.

So you can see prices for arbitrage between mtgoxUSD and btceUSD (for example) varying with volume.

3. We extended the usual color coding from 2 to 4 colors:

- orange means there is positive price difference - you can buy low at one exchange and sell high at another one (but beware transaction fees and other commissions!)
- yellow means there is no arbitrage and negative bid-ask price difference is less than 10% - that is, market is efficient.
- white means there is no arbitrage but price difference is more than 10% - it means there is a market making opportunity, you can try to make money by putting limit orders at these two exchanges
- black means there's not enough volume on one of the exchanges

The 10% threshold is based on our subjective feeling of illiquidity and is more or less arbitrary.

4. At the top of the table you see best available execution price for the lot. You can use the percentage as a measure of bitcoin markets efficiency. The square is usually orange - so best bid usually is higher than best ask because of inefficiencies! But it's rather hard to capitalize on this difference as it requires a complicated execution strategy and will probably be eaten by different fees.  

The free version of arbitrage table is delayed by 6 hours - it shows quotes 6 hours from now. The paid version (available after you subscribe with a modest fee of 0.5 BTC a month) shows realtime quotes (fetched from exchanges using their orderbook API every 15 seconds and updated using web sockets just like the charts).

Also note, that these days arbitrage opportunities only happen during price swipes, so keep watching Smiley

Good luck in your profit seeking!

Bitcoin Analytics now has "Arbitrage" tab.

Very, very nice!


Why only OpenID?

When I try to use my preferred OpenID login:

 http://openid.anonymity.com/YesIPreferToStayAnonymous

I get:

 Error: Cannot retain discovered information; the provider does not contain the required attributes

All I was trying to do was to see how much do I would need to pay to get this arbitrage in real-time?

Thank you, Stephen for your interest.

You are absolutely right, having only OpenID is not enough. We wanted to get the service up and running as soon as the main framework is ready and stable enough. Thus we limited social login options to OpenID providers.

We are already working on adding non-OpenID social login providers Facebook, Twitter, Vkontakte and others.

We chose not to implement the usual password based login in addition to social login because it takes too much work to make password-based logins secure. OpenID is by design not vulnerable to user database theft, and allows users to use very secure authentication schemes if they wish - certificates, two-factor auth etc.

We are sorry for this inconvinience with your OpenID login attempt. We'll try and do our best to fix this embarassing problem asap Smiley
Hope this will not make bad impression on you Smiley

As for the subscription price, it is 0.5 BTC per month and includes both arbitrage table and full set of charts. We'll make subscription fee more prominent. Thank you again for your feedback.

Hi, sorry for this inconvinience.

In general it takes some time for our service to get payment notification.
Normally it should take 1 confirmation but some time it can take longer.

Hope this will not make bad impression about our service.

Thank you for your patience and understanding Smiley

Hi
a few questions and recommendations:

on charts table:
what does
MKT
VWAP
mean?

on arbitrage table:
if I understand correct the numbers
eg:
-5.xx -6.xx%
means the first number is absolute amount in USD and the second in %, - but I think % is the most important number and therefore has to be big and bold or so?
it will be a nice feature if the highest (1 or 2) number(s) in % is in another color and/or bold or major
the colors are very confusing me...
why don't you take the colors used in whole world in traffic lights  (red, Yellow, green and perhaps white or black as the 4.)
that is much more intuitive (orange is too much near red for me and means stop for me...)

I hope this is  constructive review for you Smiley
thx

Hi, ewibit!

Thank you for your constructive attitude Smiley We really appriciate it Smiley
Please be sure that your opinion is valuable for us. As opinion of all our active and would be customers Smiley

You are right there are plenty to be done to improve the service and to become mature and actually really useful.
We wanted to assure you and all our customers and guests that we are working hard to make this improvement come true.

You are absolutely right about those terms. The documentation lacks their description. And we will fix this inconvinience with our planned next update which I hope come very soon.

But to clarify your question I can tell that we used fairly common abbreviations for the sake of simplicity and minimalism.

MKT usually means Market Order (http://en.wikipedia.org/wiki/MKT) . So the full name of the term '1000 BTC MKT Exec Price' reads - 1000 BTC Market Order Execution Price. This is exactly the price at which you actually can buy/sell 1000 BTC on a given exchange in one market order. The idea to calculate this parameter was primarily from the trading convinience point of view. We assume that it might be useful to know current market execution price in conjunction with certain voume than just best price without relevant volume.  

VWAP stands for - Volume Weighted Average Price so label 'VWAP Last 1000 BTC Traded' answers the following question: What was the price of last 1000 BTC sold or bought respectively. Here we assume that it will be interesting to compare how different Market Order price to sell/buy 1000 BTC from actually traded last 1000 BTC on the current market. Last 1000 BTC sold or bought could be traded in one big chunk or in a lot of small 0.1-1.0 BTC trades. To tell at which price it was sold/bought we calculate average price of all last trades until the sum of those trades equals 1000 BTC. Thus we believe this allows us to use the term VWAP in this case.


As for the arbitrage table format you are also absolutely correct. It must be some how reworked. I can agree with you that percent is more relevant for analyzes and must be better and differently highlighted. Your suggestion about colors coding is also relevant. And please be sure we are carefully gathering all such suggestions from all our customers to collect as much as possible opinions. Then when critical mass of such data is collected we will be able to analyze it and make a decision what must be done here and there.
Once more thank you.

From our side I can tell that before the release of this service we were very concentrated on wide variety of technical issues: such as stability of the service, performance issues, user accounts and payment processing. Interaction with exchanges orderbook and trading api. Collecting data in database and on and on and on...
So we ask for your understanding that we choose to delay some questions and decided to solve them not optimally but from the simple aesthetics point of view.

Once more thank you for using our service and giving us your constructive opinion, it is very important for us.

12 US Dollar tickers: mtgoxUSD, btceUSD, cbxUSD, cryptoxUSD, intrsngUSD, bitstampUSD, bitmarketUSD, bcLRUSD, bitfloorUSD, vcxUSD, btctreeUSD, btc24USD - note that we had to disable btcex

8 Euro tickers: mtgoxEUR, bitmarketEUR, vcxEUR, intrsngEUR, bcEUR, bcLREUR, bitcurexEUR, btc24EUR

2 Chinese Yuan/Renminbi tickers: mtgoxCNY, btcnCNY

Hi, thank you for your details.

My understanding is that the chart you propose must be calculated from data collected over several weeks. It is not currently possible with Bitcoin Analytics engine.

Providing realtime capabilities and sustaining higher visitor flow during market rallies and crashes while keeping operational costs low took a lot of engineering effort. So far we have a very good survivability record - few times we were up when our competitors were down.

It also meaned that we couldn't be a jack of all trades - we decided to concentrate our efforts on 24 hours time frame with 15-second readings.

Although we have distant plans to cover larger timeframe with coarser granularity, we think that Bitcoin community would win if we focus on getting most out of what we have already developed. Intraday data analysis is a significant sub-industry within algorithmic trading, many interesting visualizations can be done with intraday data.

Looking forward for new intraday visualizations,
genuise and nimnul.

Hi, thank you!

can you please be more specific?

There can be two directions with cross currency.
Charts and Arbitrage.

We have some ideas about advancing arbitrage view, and there can be several moments to consider to be able provide useful tools.
For example the question is what kind of arbitrage table structure should we implement to adaquetly represent cross currency opportunities.

The problem is that there are big number of variants how to do this. We are interested in all suggestions.

Also there is interest from our customers in providing orderbook table for each exchange.

I don't trade actively enough to merit a subscription, but I just subscribed nevertheless out of curiosity.

I have a suggestion is for the Order Book Volume chart: could you make 2 different scales for the asks and bids (an additional one on the right of the chart or whereever for the asks) and align these scales by some average recent price? That way, traders that use the orderbook to make decisions could see more easily which way it leans and when there are crossings.

Hi, thank you for supporting us,

and for constructive participation in discussing tech issues in other thread.

Your are absolutely right about Order Book Volume chart - this is already planned with our soon release.
This particular feature is directly connected with implementation of the mtgox stream api full order book volume chart. In case of full order book the USD bid volume is ~1.8 M while BTC ask volume is ~0.24M.
and this difference is clearly visible. Thus we cannot display it on the same scale.

And we also plan to release multiple subscribtion plans to allow people who do not trade actively like you to try our paid service and stay within budget.

thank you,
once more

and till then

i'm enjoying your service as a paying customer, thanks for your product.

one thing that would improve the usability of the tables would be the possibility to specify a custom BTC amount for the charts and arbitrage tables, and not just the fixed increments of 10/100/1000. when the user enters a specific amount, the calculations should be made with that amount.

thanks.

Hello, dudel42, thank you for being our customer Smiley

And thank you for your sugestion. We really appriciate every feedback.

As for your suggestion we can agree that the custom trading volume is one of the desirable parameter to consider for practical trading. And we were considering such an option while designing the architecture of the service.

Here currently we have one obstacle which prevented us from implementing this feature initially: if we consider providing this calculation in 24h charts for every customer this will mean that we will need to store separately custom sequences of calculated data virtually for every customer. This as you can understand will need huge amount of resources which will significantly increase our expenses and inavitably the end price of the service.

So currently implementing custom historic data is not an option.
 
But what probably is more reallistic for arbitrage is to calculate CustomVolume MKT Exec Price for every ticker on client only. This means increased performance of browser(probably not significantly) and no historic data between reloads of the page. This is just at first glance.

Here it would be intersting to hear your opinion of this idea?

Thank you

ello. I'm interested in your website and possibly subscribing. However with the recent sharp increase in value of bitcoins I was wondering if you could provide information on arbitrage trnsactions for as little as 1 bitcoin now?  Also how much is the subscription? I know it was 0.5 btc/month but I'm hoping you'll have dropped your rates now!

Was my post useful to you?  Tips graciously received!

Hi, thank you for your interest in service.

Normally we reconsider subscribtion plans prices once per month. And last time we corrected them on apr 1.

Full access will cost you:
0.002 BTC a day, 0.03 BTC a month, 0.05 BTC for 2 months

hope this help.

if you have further questions we will gladly answer them.

Hi, as a subscriber is it possible to access data older than a day? Also can we get an option to have the volumes in either BTC or USD on the same axis, instead of having bids in USD and asks in BTC on separate axes?  It's hard to compare two plots on different axes in e.g. the order book volume chart, you can only see the relative fluctuations on either axis.

Hi,

Thank you for supporting us.

We have a plan on adding month long charts with candlestick aggregation but now it's not possible to see data older than a day.

There is a problem with having volumes in either BTC or USD on the same axis. Often there are spam orders on both sides of orderbook: someone sells 1 BTC for 1 billion USD and someone buys 1 billion BTC for 1 USD.

For bids, only USD volume is "real" and BTC volume is an arbitrary number put by whoever placed the order. For asks it's vice versa: BTC volume is "real" and USD volume can be set to arbitrary number.

If we put both volumes in one currency it will not help you to compare them. So there should be a method of filtering meaningful depth from fake depth and we couldn't find a good one. Do you have ideas?

Best regards, nimnul and genuise

How about calculate the "real" volume yourself by e.g. multiplying the USD volume by the order price to get the true BTC volume?

It is not a problem to multiply usd bid price and volume of btc in each bid order.

But as nimnul explained, that simple multiplication will not get meaningful number.

The problem is that not all bid orders have meaningful, as nimnul stated a "real", price. e.g. if someone places a bid order to buy 1000 000 000 btc for 1 USD, in other words buyer expects to buy 1bn btc at 0,000000001 usd/btc. does this price make sence for your analyzes? Such order will be never executed.
Thus such orders represents spam, not real , fake data in the orderbook.

In other words this one fake order will make bids line several orders higher than asks line. 1bn btc on bids side which are not existent and 100k btc on the asks. This really does not make sence. Can you agree?

There are a lot of such orders, and their combined volume just obscurs the true picture.

If we exclude those fake orders we will see the true picture.

It this clear?

So the question is how to tell which orders have to be excluded and which not?

There is no common agreement on which order have to be counted as meaningful and which is not.

So how to find this common filtering creteria is the main question.

Do you have any ideas on how can we solve it?

One way to filter it would be use an discount factor based on distance from the top order. The discount factor can be exponential or linear.
An exponential discount factor would be something like e^(-ax) where a is some scaling factor and x is the distance. A linear discount factor could be something very simple like a(x/x_top)

For example, say current top bid is $60 and there's a bid for 1000000000 BTC at $1.

The exponential discounted volume with a = 1 is 1000000000 * e^(-(60-1)) = 2.3802664e-17, i.e. negligible. If we want to give it a bit more weight we can decrease a to 0.1 which yields 1000000000 * e^(-0.1(60-1)) = 2739444.81877.

The linear discounted volume with a = 1 is 1000000000 * (1/60) = 16666666.6667. Give it more weight by increasing a.

The same thing could be used on asks. Personally I'd like to see orderbook volume charts in USD and BTC (option to show volume in USD or BTC). I'm also curious if the spam orders on both sides simply cancel out, what does the chart look like if you just multiply without discounting? If I could get some raw data I can play around with the parameters in MATLAB and see what values are reasonable.

For the depth chart it's not necessary to discount, simply convert BTC to USD and vice versa at the price of each order to make volume on each side use the same currency. Again it would be nice to have an option to toggle between BTC and USD.

Another suggestion, add another series in the VWAP chart for both buys and sells, and have a control to show/hide each chart.

Actually, is your data the same as https://data.mtgox.com/api/2/BTCUSD/money/depth/full? I could just play with that data if it's the same.

On the depth charts for mtgox you can see that we limit ask with 1000 usd/btc price and you can visually estimate what discount factor will be useful.

Ok, I made some charts to demonstrate. The total discounted volume for bids and asks in USD is shown beneath each.

Here's the raw data I was working with
http://i.imgur.com/yPjLtle.png
Bids: 12170767.4644583
Asks: 27476862169015.9

And here's the depth chart up to twice the top bid
http://i.imgur.com/BRxe2b6.png

Here is the exponential discount factor I described before, it prioritizes prices close to the spread.

The formula for the discount on bids is e^(-a(highestBid-bid)), and e^(-a(lowestAsk-ask)) for asks.

Here's the discounted volume:
http://i.imgur.com/CSZjOCi.png
Bids: 105023.402931941
Asks: 23900.6565377794

That was a little too restrictive, relax the scaling parameter a bit to a=0.1:
http://i.imgur.com/K0SOpL1.png
Bids: 1522439.36415067
Asks: 1236490.55085024

It can be relaxed further to include points further down the line:
http://i.imgur.com/b8VT37W.png
Bids: 3262099.42799612
Asks: 2777887.40515259

Alternatively to give full weight to the majority of the orders, use 1-e^(-a*bid) for bids, and max(0, 1-e^(a*(ask-lowestAsk)-highestBid))) to create a symmetrical bandpass filter about the spread.

Here's what it looks like with a = 1:
http://i.imgur.com/1aToRt2.png
Bids: 11970104.7601015
Asks: 9177170.77805910

Restrict the further out values a little with a = 0.15:
http://i.imgur.com/PowevBb.png
Bids: 11091817.7195716
Asks: 8799423.98610072

A simple linear discount function, use 1-(highestBid-bid)/highestBid for bids and max(0, 1-(ask-lowestAsk)/lowestAsk) for asks
http://i.imgur.com/9b6neS5.png
Bids: 6158532.21541063
Asks: 5225588.99409854

Depending on what kind of analysis you want to make I'd say either the bandpass function with a=0.15, exponential function with a=0.1, or linear function would all work fine.

One more thing instead of using a line plot for depth and trade volumes it might be better to use a stacked bar chart. Right now it's really hard to hover over one exact datapoint to see its values, and it doesn't really take advantage of horizontal scaling.

Hi, Masqurin,

this is exactly a kind of thoughts we really like and appreciate. Thank you for your time and efforts.

We must admit that the density of information you gave us is quite high and we need to digest different parts of it to be able to understand what is easy and what is not to implement in our current application architrecture.

It would be really helpful if we can exchange further to see what limitations we currently have and what can be implemented and in what order.

As for the math of the filtering it not a problem to implement filtering as is, but the next question is:

currently while preparing data for display client we need to make some steps to solve several problems

1) our server should be able to gather and recalculate all parameters once per 15 seconds and not overload the processor

2) we then need to store limited part (not all) calculated paramateres in memory in 15 second buckets in such a form to not exceed the memory limit of our machine

3) then we need to prepare data to transfer it to the client browser - and again to have resonable amount of data to transfer (keeing in mind that we already are using float data type, gzipping) it takes some times up to 10 seconds to load the whole data to browser

So adding additional parameters to calculate is not the main problem, but to decide what to transfer to client and and how to display it could be a difficult task.

For example: as for the orderbook volume we have two series per ticker, and those data currently represent actual sum of all USD and BTC in orderbook even if orders are spam orders, and if we decide to filter out spam orders in order to visualize bids and asks series in the same units then we will loose our original genuine data which is also make sence in its own context (real not filtered amount of USD and BTC in orderbook)

What do you think about this particular problem what would be good solution from the user point of view to maintain both series together on the client to be able to compare them or just to leave filtered and to abandon the original full volume series?

Quote
I'm also curious if the spam orders on both sides simply cancel out, what does the chart look like if you just multiply without discounting?

I mean you prefer to have both pair series or only one pair?

also as each filtering method will produce differernt series would it be practical to maintain all of them (thus multiplying serires) and toggle between them or just one. If one which one would be the most practical for analyzes on your opinion?

Without a detailed rundown of your system my ability to evaluate your performance capabilities is limited but I'll try.

1) Server-side performance shouldn't be a problem for these filters, they only take O(n) additional arithmetic operations per update (n = number of orders in the orderbook) and the same amount of memory as whatever you're using to store the volume data right now.

2) When sending data to the client during an update, do you send all data or just the update delta? I'm not sure what sort of data the client keeps track of, but assuming you have all the calculations done server side the update delta should be very small, for each graph you should only need to send one additional datapoint per line per update.

3) It seems the client is receiving data for all currencies and exchanges, even the ones that aren't shown. You can avoid some data transfer by sending it selectively. For example, I only care about mtgox data in USD,  there are 13 other tabs containing data I don't need. What I would do is have an option in the user's preferences for the default exchange and currency, and only load and display that data by default. Request and subscribe to the other tabs only when the user requests it.

4) Similar to 3), you don't have to show all charts by default and the client doesn't need data for hidden charts. As I suggested before, add a control to hide/show each chart, and have an option for a default set of charts in user preferences. Only request and subscribe to data for a chart if and when it's shown.

For each series you'll have 24*60*4 = 6240 datapoints. Each datapoint is two floats, i.e. 8 bytes, yielding about 49kB of raw floats per series (not sure how the data is structured, e.g. if you're using JSONs there will be more overhead). I'm not sure what kind of compression ratios you're getting, a cursory search suggests gzip doesn't do a very good job of compressing floats. Still, it shouldn't be a problem for most people and you may be able to reduce it further by using a compression algorithm that's optimized for floats.

With regards to the filtering I suggested, I think there's no real point sending the raw data to the client; as it is the data is only useful for showing relative change in volume for either bids or asks. Seeing as orders that are very far from where the trades are happening don't really affect the prices, I don't think you lose anything by reducing the weights assigned to them. In fact by discounting spam orders and far-out orders it would better link relative change in volume with change in price since the orders that matter are given more importance.

Nevermind that request, I made a chart for the data and "fake" orders do indeed have a large impact.

Quote

I think picking one is fine, which one to use depends on the purpose of the chart. The exponential function (a=0.1) prioritizes orders that are very close to the current price and hence should be a better indicator for short term market movement. The bandpass function (a=0.15) is closer to the "true" total volume but is more sensitive to volume changes that are very far away from the current price. The linear function is midway between the two but I'm not sure if it can match the benefit of either. I would run all three for a while and see what they look like, and then analyze the strength and weakness of each.

More UI suggestions: 1) Make the height of the chart area scale with window size, if you've got chart height scaling working it would be really nice to hide a few of the charts and have the rest be taller. 2) Move the axis labels to the right side of the charts, that's where new data is coming in so that's where people will be looking. 3) Add an option for a dark colour scheme, I think most people prefer something like http://bitcoinity.org/markets or http://bitcoin.clarkmoody.com/. 4) On the VWAP line there are markers for each point, but not on the other price lines. I think it looks better without markers.

This what I suggested some time ago for discussion. And I think in this case it would be good to use filtered  raw data to have meaningful estimation for the price.

How can we call this parameter  - expected market price or general market expected price? or? Is there any existing parameter for this in financial world already?

I'm not sure if there's a term for it, but total bids:total asks seems clear enough. I'm not sure if filtering would improve it and if so which filter, so again it would be nice to capture some data and compare.

Another one that would be good to have is a moving average of the buys volume:sells volume ratio over windows of e.g. 10m, 1h, 3h, etc.

The charting library we use supports post-processing with moving average. See the input box at the bottom chart at http://dygraphs.com/tests/range-selector.html

If it's ok we can easily add that input box for moving average window size to all the charts.

4) On the VWAP line there are markers for each point, but not on the other price lines. I think it looks better without markers.
If you zoom the VWAP chart you will see something like this:



The markers are not for every point, but for each point (15-second "slot" as we call it) with trading activity. So here you can see that a large trade activity at 14:29:45 shifted VWAP, but a larger trade volume at 14:33:00 had almost no impact on the price. Removal of the markers will obscure this information.

Of course when you zoom out to default zoom level it starts looking ugly, but we didn't knew how we can improve it without information loss.

In addition you can see here why we chose to plot "buy" and "sell" trades separately instead of joining them with a single line as our competitors do. We show that trades are performed at two different steady prices instead of zigzag pattern you often see on last trade price charts without bid-ask separation and volume weighting:

I'm not sure I understand what extra information is conveyed by the points on the VWAP line that's not already in the volume chart - as far as I can tell the set of points on the sell line show that a bunch of trades happened around 14:33 but only one of them had large volume as indicated by the corresponding point on the volume chart. The fact that the price didn't change seems incidental.

In addition you can see here why we chose to plot "buy" and "sell" trades separately instead of joining them with a single line as our competitors do.

Yeah, I like the separate volumes for buys and sells a lot. Though the problem with using two line plots for them is 1) the line one with the higher volume in a timestep is going to obscure the lower one and 2) it's hard to tell how much total volume was traded for that timestep. A stacked bar graph with the buy volume on top of the sell volume would solve both problems and as a bonus is visually more clear - with a line plot the slope between points suggests the value is changing between points while a bar better represents the "slot" being filled with volume.

Here is one question, as I can understand you meant trading volumes here. What if buys is zero in current slot? or more over what if sells volume is zero or very small? In those cases the metric will have no meaning. Or what did you mean?

Here is one question, as I can understand you meant trading volumes here. What if buys is zero in current slot? or more over what if sells volume is zero or very small? In those cases the metric will have no meaning. Or what did you mean?

Perhaps (buys-sells)/(buys+sells) (if buys+sells=0 then 0) in that period then. The idea is to compare the relative volume of buys and sells in a time window to see if the market is bullish or bearish during that period.

Also the charts seem to be glitching out periodically where nothing is updated except sells. Happens at the same time on multiple exchanges so I assume it's not on mtgox's end, what's up with that?

Aha I see now, actually we just wanted something like this when we tried Time last x traded chart.

Also the charts seem to be glitching out periodically where nothing is updated except sells. Happens at the same time on multiple exchanges so I assume it's not on mtgox's end, what's up with that?

There can be several causes of this
1) some times exchange just does not return request  - in this case the best option we have to assume the last available data as actual
the problem can be on exchange side - btc-e was ddos'ed or our hosting did not get connectivity.

2) in case of gox - we use quite complex logic for stream api client wich accounts for several cases:
  - stream api can connect us but does not subsribe to any channel in this case we need to detect that stream is dead after some timout and reconnect
  - if we could not reconnect for 15 minutes we force orderbook reinitialization - request full ordrbook via http
  - also gox can disconnect/reconnect us arbitrarily often and each time we connected again and subscribed we need to reinitialize orderbook state requesting full orderbook via http but we cannot request too often otherwise we will be  blocked by gox. thus we maintain hysotry of requests for each currency and wait in timeout if necessary some times for on hour and rarely for 24 hours.

all those timeouts is subject to changes and tweaks cause mtgox every time shows different and new patterns of how their engine can behave.

in all those cases we use last know state of orderbook to be able to assign trades to bid or aks side.

3) bitcoincharts can:
  - be down
  - we just do not connection to bitcoincharts
  - bitcoincharts delays some trades  - in this case after some time bitcoincharts cn send all dealyed trades and if our application was still up it sorts all of them by timestamp to its time slot and assigns bid/ask side, but if our application happend to restart due its own uncought exceptions then delayed trades could not come to us at all.

So if orderbook state is not changing you can see flat line.
If trade time is increasing then trades are not coming.

so you can imagine that thigns are a bit complex here.

thank you for your attention to those details

Note however that sells are being updated but buys are not. That rules out connectivity issues since buys and sells are on the same channel at least for mtgox. Also the same issue on three different exchanges at the same time is fishy.

To clarify, do you get your data from bitcoincharts or using each exchange's API directly?

When orderbook is not updated its median price is fixed and during this period actual trades can go up or down, thus they all automatically assigned to the same side.

This would not be a problem if bitcoincharts could collect and resend trades with original bid/ask assigned from exchanges. I contacted bitcoincharts before and they answered that they do not have any plans to support this feature unfortunately.

So we assign trades to bid/ask side on our own based on currently available orderbook data. This was very simple solution.


To clarify, do you get your data from bitcoincharts or using each exchange's API directly?

We get orderbooks directly from exchanges.
mtgox http full orderbook + stream api
btc-e http orderbook is not full - we could not manage discussion with them about possible solution yet, cause they are too busy on their own.

All trades for all exchanges we get thru bitcoincharts. this is the most simple solution.

we have plans to implement hybrid mode for mtgox trades which will get trades from stream api and in case stream api is down it will automatically switch to bitcoincharts stream

something like this

I just was thinking about how visually this shart will appear - as I can understand it will got positiv if buys greater than sells and negative otherwise. The value will not exceed +/-1.

But how this an be modified to be ale to visualize not only side of trade but also the absolute siginificance. I mean to tell whether there are only small sells or big. Can it be some how combine in this idea? Of course we always can have existing already absolute trades volume chart but I am just curious.

What is your opinion?

To show the absolute scale just don't divide by total volume, though I'm of the opinion that if you have a stacked bar chart for the trade volume then that will be obvious.

I'm begging you to remove BTC24 from the arbitrage page.... There's no purpose anymore and it's ruining the purpose of being a member of your service. I'm a paid member and I would be able to use the arbitrage page if it was fixed! You should also remove Vircurex as it's useless for arb, and the price displayed is rarely accurate to the actual price... thanks!

Hi, thank you for your feedback,

as for the btc24 it is absolutely not a problem to disable it.

But you also ask about Vircurex price which is not accurate? Can you elaborate about it? What exactly is wrong with it?
Vircurex orderbook data is requested directly from exchange api in the same manner as all other supported exchanges.

I understand that Vircurex almost does not have enough volume for arbitrage but their prices are calculated using the same formulas as for other exchanges are completely erronous? or what exactly did you mean? It would be helpful if you can explain this point.

Thank you

Hi, pm me please your account bitcoin address for me to be able to identify your account.

Usually server waits for notification message from our payment processor service. We activate even is there is 0 confirmations.

However sometimes payment notifications come delayed for 10-20 minutes, and rarely more than on hour.

So I hope for your patience.

thank you for supporting our service.

Is it possible to change the OpenID provider? I'm using myopenid and it is down. Thus I cannot access the page with my subscription currently. Given that it is unclear how soon myopenid is back up I would like to change to a different OpenID.

First, a quick review on the sign up process. It was as bitcoin-analytics.com described. I sent the fee to the address and after a few confirmations (I think it became active after 2, but it may have been 3) the subscribe banner was gone and the data was no longer delayed. Although I have not made any trades based on the data yet it was well worth the fee (seemed cheap to me). The data makes it easy to see much more of the bitcoin exchange picture.

Ok, dumb question time, but better to lose face then btc! Do the arbitrage numbers\comps take fees\costs associated with the individual exchanges into account?
The answer probably exists somewhere on this board or in a google search I didn't think of, but I have to ask.


Are there any additional docs on the implications\meaning of this type of data I should read? I am unfamiliar with financial stats, and I know there is a lot that goes into this I am missing.


Seems like a great service and I hope it is financially viable in the long term!
 
Cheers,
aynstein

Hi, thank you for being our customer and for your review.

We really appreciate your opinion.

As for your questions:

The arbitrage charts/numbers does not include any fees and costs associated with different exchanges.
While we understand that integrating those fees would be of greate use for traders this was not our main priority. And also different exchages do have different fee schedules which may depend on several factors for each trader individually. Some of them not. Which makes the task on supporting fees and costs in caculation more complicated.

Currently we assume the simpliest variant when each person calculates his percent of fees and costs and just applies them to the naked percent difference we caclulated base only on orderbooks of exchanges.

Once again we caculate price based only on orderbooks.

It would be good to mention once again that our caclulation algorithm repeats the matching engine of the exchanges to caclulate which orders will be filled in order to sell/buy 10, 100, 1000 ... BTC. The main point was and is that it is not obvious that when matching engine performes matches for limit order not all matched orders are filled with the same price. Thus final price of your sold/bought BTC cannot be caculated by multiplying your order price and volume.

Instead you have to summ up all matched orders prices and volumes and caculate average price which will be the actual price of you filled order.

Here is an example of how we caculate price of the filled 10 BTC order.



If you still have questions feel free to ask them here.

As for your other quesions thy are too general can you probably be more specific?

Once again thank you for sharing your experience and being our customer.

Hi, I am not sure about your question what do you mean exactly cause we have added support for btcChina long ago.

As on charts, depth and liquidity and as on arbitrage tab.

you can find btcChina under CNY currency selector as btcnCNY ticker.
The same btcnCNY ticker for btcChina is used on bticoincharts.com and other services.

If you have any questions and suggestions please feel free to ask again. And we will try to clear them.

Is it possible to see the "Trade Volume" chart for the past, for example 6 months for *all* currencies?

Ie. it would contain the trade volume for all currencies (USD, EUR, CNY, etc.) on all exchanges (Mt. Gox, Bitstamp, BTC-e, etc.) all combined together, and it would go back a long time (preferable back to the previous bubble).

I want to compare the total trade volume with the previous bubble (or whatever this turns out to be).

Hi, thank you for your suggestion.

We have plans to work on candlestick charts for longer timeframes, but the first version would likely have a shorter timeframe or 1-2 months

as for your suggestion about consolidation of trade volumes of all exchanges for a longer period of time we can say this is a nice idea. And we will include it into our todo list, but not sure about the time when it will be enabled.

Let us think about it, whether it is possible to find a quick and simple solution.

Sounds great! Please let us know in this thread when the feature arrives. I'd certainly be willing to pay 0.002 BTC for a single day's access to view these charts.

On your no subscription price chart, looking at Q10000, the spread ranges from 30 to 60.
at Q10, Q100, Q1000 the spread ranges from -20 to -60
Are these colored wrong - or am I missing something?

Ok,

allUSD represents a consolidated orderbook of all USD exchanges.

10 BTC MKT Exec Price shows the price which you will get when matching engine actually executes you market order to buy or sell 10 BTC. That is why such a name for the chart.

when you see bid price is greater than ask price this shows that arbitrage opportunity exists on the market in general. For less BTC volume the spread is greater than for bigger BTC volume because not all exchanges has the same orderbook depth ( enough BTC supply or USD supply).
and at some point the arbitrage opportunity starts to decrease with increasing volume.

If you take a look at depth chart for allUSD you will see the lower trianglular part where bid prices are greater than ask prices.
if you take different between bid/ask price on the very bootom side of the trianlge the difference will be maximal but when you start moving the line to the top the difference will reduce until the top of the trianlge where there is no spread at all. The hight of the trianlge corresponds to the supply volume. And starting from the top of the trianlge the spread will be negative meaning that you will not get profit but loss.

Hope this helps, if you have more questions please feel free to ask, and to read further our Why part.
There you can also find some useful explanation of the charts.

Let me try to explain differently...

Charts/allUSD/1000 btc Price -  at 17:30  bid 512  ask 482
Charts/allUSD/10,000 btc Price -at 17:30 bid 471  ask 518
one is the inversion of the other. (approximately)
10,000 is correct
chart for 1000, 100, 10 are inverted

The odds of the aggregate bid price being higher than the aggregate ask price by $40 and no trades happening
on any of the exchanges represented is about nill. And yet on your charts, it is all day.

See the added pic.
If the average ask price was $475+-
Why would the average of people bidding be $526+-
I would think that a close analysis would reveal that meeting the asking price is sufficient.

Hi, thank you for your screenshot and question.

as I told before tha allUSD orderbook contains all bids and asks orders from all supported USD exchanges.
It represents a fictional exchange which we assume with approximation as a general representation of the whole USD market.

The main difference of this fictional exchanges is that the orders can be crossed sometimes ( not always) even for 1000 BTC. In other words some times the USD market is so inefficient that on on exchange there is relatively cheap ask price for BTC and on another there is a relatively higher ask price for 1000 BTC.
Actually the situation is more complex cause there are always more than two exchanges.


This inefficience is reduced when you increase the order volume it turns out that on those exchanges there are no more crossing orders and prices becomes comparable among different exchanges, and we see normal picture.


What you see is orders from different exchanges are crossing. And if on one exchange like mtgox, or bitstamp there are a lot of trades on the other hand on small exchanges like vcxUSD anxhkUSD there are almost no trades while their orderbook still has bids and asks orders but they are sitting idle there and waiting for somebody exploiting this potential arbitrage opportunity.

One more existing potential arbitrage opportunity does not mean that this opportunity is realizable, because there could be a lot of problem to deposit and withdraw funds to finish the combination, or fees could eat all profits.

Our task at bitcoin analytics we see as at least showing those potential inefficiencies of the markets in general. And providing efficient tools to analyze all the details as much as possible.
 
Hope my answer cleared some questions. Please do not hesitate to contact us more if you have any more questions.

I understand completely what you are saying.
AND
I am saying that your chart is accurate except on the 10, 100, 1000 allUSD charts,
RED should be BLUE and BLUE should be RED.

Hi, here is what we have currently in consolidated orderbook.

you can see original exchange near each order.

as you can see the best bid price is on anxhkUSD and on mtgoxUSD and there are enough USD to fulfill 10 BTC order.
The price will not be 598 but somewhere between 595.44 and 598.71  
(
4.49 * 598.71795 = 2688.2435
1 * 598.46154 = 598.46154
1 * 595.89744 = 595.89744
0.0039 * 595.85895 = 2.32384
2.7128 * 595.44001 = 1615.30965
0.7933 * 595.44 = 472.36255
(2688.2435 + 598.46154 + 595.89744 +2.32384 +  1615.30965 + 472.36255 ) / 10 = 597.259852

On the other side of orderbook you can see vcxUSD order and bitstampUSD order.
There are enough BTC to fill 10 BTC order. The price will be somewhere between 504.99 and 514.9 (
exactly
0.1132 * 504.99 = 57.1648
and
9.8868 * 514.9 = 5090.7133

(57.1648 + 5090.7133 ) / 10 = 514.7878

so for 10 BTC Volume
BID price (color Red) is  597.259852
ASK price (color Blue) is 514.7878

Can you please check whether my calculations are correct?

I need someone to correct my account.

There is a bug in your subscription system such that when someone clicks one of the buttons twice in rapid succession (before being on a plan) two invoices are generated.

Unfortunately, despite paying 0.015 BTC, my account remains -0.015 BTC because of the second erroneous invoice.  

Could a staff member please correct this?  My email is ...@...com and I am signed up through the Google OpenID system.

Hi frito,

Unfortunately historical data is not available at the moment. Paid account only eliminates delay in arbitrage table and gives access to separate exchanges instead of data aggregated by currency.

We are working on candlestick charts, but they will take few months to get ready. And even at that point the timeframe of displayed data will probably be shorter than 6 months.

We do have full orderbook archive for last couple of years, but it's in an inefficient format and thus we are not ready to provide any access to it. If you can program, we can try to give you samples of our datafiles and run your script on the full dataset.

hi nimnul

I can appreciate the bandwidth cost, client side memory and cpu load for running online tick data chart, there is no need for that anyway(imo).

I was more thinking if you can offer simple flat file Dumps on Dropbox or some such.

Yes I do have experience with big data manipulation, datamining and coding... So I can take a look at the raw data you got and make a script for the transformation of the very top of the order book i.e. produce timestamp, best bid price, best ask price, bid volume, ask vol.(perhaps also incorporate last trade info)

So please PM me a download link for the data sample.

cheers

Hi,  thank you for posting here. We posted message in our social section.

Quote
Hi, everybody, as we posted some days ago we found the problem between our payment processing module and our payment processor provider. We are currently investigating the problem further.

At the moment we identified that recently there were 7 payments and we got notified only for one of them. This means that at least 6 customers did not get their subscription activated. If you believe that you are the one whose subscription is not activated please contact us via support@bitcoin-analytics.com and we will fix the problem Please send your account bitcoin address for us to identify your account.

Currently we had to suspend any new subscriptions until we find the cause of the problem and find working solution.
Thank you for you understanding and support.

Please if you have any question post here or send us email to support@bitcoin-analytics.com

with all respect
bitcoin-analytics.com team

So currently we have suspended any new subscriptions until we find the cause of the problem and solution for it.

There are some customers who contacted us and we are fixing their subscriptions.

We advice for all existing customers who wants to prolong their subscriptions should postpone any payment until further announcement.

thank you all for supporting our work.
Hope for your patience and understanding.

Hi, everybody!

As we recently wrote we had problems with our bitcoin payment provider. We decided to abandon our old payment provider and implemented support for new one. This means that we had to regenerate bitcoin address for all accounts which have their bitcoin addresses assigned.

Old addresses should not be used for any new transactions. Please from now on use only new bitcoin addresses.

We also re enabled "create account" buttons for newly registered accounts.

For each existing account with newly regenerated address we also placed a personal notification message to ensure that transition will be as smooth as possible.

If anyway you have any problems or questions regarding payments please contact us posting here or sending email to support@bitcoin-analytics.com and we will try and find a solution for you.

Thank you for your understanding patience and support.

I have one suggestion. It would be useful if you separate buy and sell volume on the trade volume chart. One simple way of doing it would be to use negative numbers for sell volume. This way buy volume and sell volume charts would appear on the different sides of the horizontal axis.

Hi, thank you for your suggestion, we really value every good idea. We will definitely consider adding this option in our next updates. Although I cannot give any concrete time frame. A lot of suggestions does not fit right straight into existing very minimal interface design. But as every service we have plans for redesign at some point in the future.

Hi, thank you for your question. We have plans to increase the display data time frame. But currently our data structure model is quite heavy and we are working on performance optimization as on server and on client. So it will take some time.

thank you for supporting us.

Yes, I see.

on bitcoin-analytics.com we calculate market price for predefined volumes. 10, 100, 1000 ...

what you see is not the narrow best price of first orders on each side of order book. But the price for 10 BTC. This price can differ from the best price because to get 10 BTC you need to go deeper into order book and account for all order prices. As more you far from the best price the more the difference will be.
In this particular case it is obvious that justUSD just do not have enough liquidity at the moment if you try to consider comparably serious investment volumes.

I signed up back on the 10 Feb for 1 month for 0.0075 BTC and you have since charged me for 2 extra months which I never wanted. I should have have 0.0075 BTC on my account (which I want to withdraw) but it says I actually have -0.0075 BTC. Can you please fix this so I can withdraw my bitcoins.

Hi, thank you for supporting our service.
 
Here is a short summary:

1. You only paid for February and March (2 months), there is no billing mistake or extra charges for 3rd month.
2. It's common that subscription extends automatically. Your refunding request for March is not well grounded.
3. However, we can refund you 0.0075 BTC as a gesture of good will should you wish so.
4. Alternatively, if a bimonthly plan with a lower fee was your intention, we can change your plan to bimonthly retroactively.

Now in more details:

I confirm that you chose a monthly plan and payed an amount of two monthly fees on Feb 10. Your subscription was activated on Feb 10 and for 2 months there were enough balance so the service continued till Apr 10.
 
Now your balance is -0.0075 because there's one outstanding invoice. If you change your plan the invoice for 0.0075 will be cancelled and invoice for your new plan will be issued.

If you send 0.0075 BTC, the service will be extended by one month since the moment of payment, not since the moment of invoice.

So as you can see there is no an error on our side.  There are no any extra charges of your account. You were only charged 0.0075 BTC 2 times, not 3 times.

As for refunding request for March service you didn't intend to receive.

If you add funds to your mobile phone, there's no way to withdraw, and they are consumed over time if your tariff plan includes a monthly payment even if you don't intend to talk. If you buy a larger scratch card to add funds than you intended, there's no way to get a change.

Bitcoin Analytics uses the same billing model.

You should have either send 0.0075 or choose a bimonthly plan of  0.00125 per month. Your demand to get a refund for April is not well grounded.

If you agree with above, we can fix your plan selection mistake and charge you 0.0125 for March and April according to bimonthly plan instead of 0.0150.
 
If you insist on a refund, since it's the first such request, we are sure it's not fraudulent, and can refund. Please send us your bitcoin address to return the money to. Send a PM to either nimnul or genuise if you consider it sensitive.

with all respect,
Andy and Evgeniy

Just to make sure I've understood the Liquidity tab properly:

I would assume that, for example, "bids 1000" means the average price one would get by executing a 1000 BTC market sell order, is that correct?

Great!

Is it possible to view data from further back than ~24 hours (I have a subscription)?

I would love to be able to go back an entire year, or more, and see the evolution of the liquidity of the BTCUSD market. And now I just realize that extending this chart isn't sufficient for visualizing historic liquidity, because this graph depends on price.

Will you consider adding a graph that displays slippage for various-sized (eg. 10, 100, 1000, etc.) market sell and buy orders? Although I'm not sure even this metric is sufficient, because it only works for single exchanges: if, for example, a single, relatively unknown, low-volume exchange has a very high bid price, then slippage will look worse than it is, because it's calculated from this bid price.

Do you have any ideas on how to create a chart that tracks BTCUSD liquidity over time, which doesn't depend on current market price?

This feature is planned. Currently in the works. Plan is to introduce historical charts with longer periods gradually, in the form of candle stick charts. And also to have more predefined volumes.

Hi, I am afraid I cannot understand your problem correctly.

Can you explaine in more detail? Normally you have to see 2 tables
1) allXXX x allXXX
2) exchangeTickerXXX x exchangeTickerXXX

along with cross currency conversion rate in the top field

can you check what exactly is not available for you?

what browser do you use? this could help us to find a bug if any.

Given that my question is why i cannot find thoses prices in table 2 and so The exchange where they quote.

The interesting thing about this is that consolidated orderbook contains all good orders from all exchanges sorted. And thus the best price for the given volume on the general market can be calculated. But there can be situation when every separate market(exchange) does not contain enough volume thus its price say for 10 BTC can be quite far from what you can get from the consolidated market.

hope this is a good hint?

Hi,

I was wondering if you offer access to historical order-book and exchange data? Is the data for your website available over an API or download?

Thanks,

S. Digs

Hi, thank you for your interest of our service. But currently we do not have immediate plans to implement api access for historical data.

Although We had only a few such request in the past. And even provided sample data for testing. Current data structure for orderbooks is fairly complicated and not optimized for distribution so those tests were not successful enough.

If you are interested please PM

Hi, you are right, this was done deliberately as apposed to other services.
The idea is that technically those two values cannot be directly compared. As bid orders represent only fiat currency which is actually present on the market and its BTC value only represents desired valuation and not always reasonable valuation. On the bid side there could be a lot of so called fake orders with extremely low price which could distort the view.

The same situation is on the asks side. The only difference that there are present actually BTC but their price also could be far from reasonable market price at the moment.

Anyway current priority is to focus on overworking the base of the system to support longer periods of data.
After this is done and stable then we can make significant refinement of the front end.

thank you for your support.

anyway I think if that should be calibrated the bid / ask in value, because although the positions may be false, remain fiat or btc available that are trying to buy or sell and can move position at a given moment, which is why really represent buying or selling force.!!

Hi, PMed you

then it would be interesting that could have a modulating bar could adjust the user, to weigh more or less the strength of the closest locations to quote

anyway I think if that should be calibrated the bid / ask in value, because although the positions may be false, remain fiat or btc available that are trying to buy or sell and can move position at a given moment, which is why really represent buying or selling force.!!

Hi, sorry for answering you for quite a while.

I am sorry but I am afraid I am still have a rather vogue understanding of what you are suggesting.

Can we contact using email or in PM to try to clear this question?

I will PM you  just in case.

thank you.

Hi, thank you for pointing to this.

I will check.

We recently made some changes to the ticker list.
Some dead exchange tickers were removed. Some new added.

Maybe there were some new bugs introduced or other problems.

Seems at the moment the problem should be solved, but still I will pay attention to this next days.

thank you once more

Your subscription will be activated as soon as we get notified about your payment, usually after 1 confirmation from Bitcoin network. But sometimes it may take longer, approx from 10-30 minutes. Please be patient and wait for some time and try to reload the page.

Is account activation broken? I sent payment for a one day pass and it has been almost an hour and the account hasn't activated. The transaction has 9 confirmations. Any help would be appreciated.

edit to add:
I am glad to report that everything is working now. Looks it finally resolved itself after a little over an hour. I guess account activation is run through a cron job? Are there any plans of adding LTC and other trading pairs?

Hi, thank you for your registration.

We are glad that this issue resolved. Account activation waits when our payment provider sends a notification about transaction. This notification data contains also number of confirmations. We activate account exactly on the moment when notification comes and we activate even with 0 confirmations currently. We did not have any problems with payments at all. Only rarely time delay between payment and activation can take longer than our subscribers expect.

We already support BTC/LTC pair. Can you please give more details what pairs do you mean exactly?

thank you once more.

Thanks for a nice program. I'm interested in being a subscriber. But I have some questions

1. What's the difference between arbitrage and Xarbitrage ?

2. I am now looking at the Arbitrage tab bitbayUSD/AnxhkUSD it's showing white colour and this figures

-21.45%
(-631.6)
B:231.25
A:294.395

I understand that B is Bid and A is ask. But what does the -21.45 % mean ? And what does the -631.45 mean ?



3. When I look at the bitstampUSD bitfinexUSD I see an yellow colour with this figures. Please explain what they mean

-0.52 %
-(14.78)
B:282.476
A:283.954

4. When I'm looking at cbxUSD and btceUSD it shows an orange colour with this figures. Please also explain this

1.55 %
(43.09%)
A:282.129
B:277.82


Once again I want to thank you for a nice program and looking forward to becoming a paid subscriber !

Hi, thank you for your questions.

1) arbitrage and xarbitrage are almost the same except that xarbitrage allows to make a cross currency comparison and make some filtering and apply custom currency exchange rate to play with the data a bit.

2) in your screen shot we consider profitability as if you buy and sell 10 BTC equal lots to close the operation.

the number in larger font means percentage of arbitrage and in smaller font it currency equivalent.
21.45% = 631.4 USD

sign means + profit or - loss.

As far as I can remember white color is for loss greater than 10%
yellow color is when loss is between -10% and 0%
and orange is for profit

hope I have answered your questions. If you have more questions we will be glad to help.

Hello, I know this seems a crazy request, but your service it's really good and if it hasn't it nobody have.
Is it possible to get a market depth history for various exchanges? Also few months will be good for my pourpose.
I really hope you record them - also if not making it apparent on the interface - and we can arrange a transfer in some way, I will be able also to pay if not exorbitant sum.

Let me know if you have this service,
thanks a lot,
a really old customer!  Grin

Hi,

Sorry for long reply, but Genuise and I were busy working on billing issues.

Yes we save all the data ever collected since April 2012. Now it's 40GB of *.xz archives.

It seems we already talked to you about the data and even sent you a sample on 18.11.2014 but you have never replied.

Let me know if you want a sample again.

Regards,
Andy

Hi, dear customers, OLD BITCOIN ADDRESSES ARE NOT VALID ANY MORE!!!

After migrating to new payment api all existing subscribers will be shown a notification message that old bitcoin addresses are no longer valid and no new payments must be sent to them.
To be able to send funds to an account, subscriber has to confirm address migration and generate new address by pressing "I confirm" button in the configure area.

All users who did not generate any address before now will be able to subscribe and generate new bitcoin address for their account.

If you are not sure what to do, or if you have questions/issues, please ask here, or send question to me or to Andy.

According to the fragment of the Arbitrage USD "10" overview, (please click the link below)  it seems to be a great arbitrage occasion between vcxUSD and a handful of other exchanges (Bitfinex, bitstamp, btce, coinbase, hitbtc, Kraken, lake, okcoin):

http://www.bilder-upload.eu/show.php?file=8c69fa-1463903698.gif

Does anybody know if vcxUSD does support USDT (Tether)? So that we can transfer USDT between vcxUSD and Bitfinex (bitstamp, btce, coinbase, hitbtc, Kraken, lake, okcoin)?

Or does the fact that an arbitrage win between this exchanges are so high indicate that USDT is not supported between this exchanges? As if it would be possible, the arbitrage win would be much lower?

Why seems the arbitrage win potential between the mentioned exchanges so high? Is there any problem to put it in the praxis? What is the hook?

Thank you for clearification. Would very appreciate your answers.

Hi,
first we have to ensure that we understand why the price we are seeing is that low and confirm that it is not just an error.

Here is Bid orders in the orderbook


And here is Ask orders.


This orderbooks you can find on the Depth tab.

On the screen shots you can see highlighted volume in the Sum column.
For the Ask orders it is very obvious that although the price in the top most orders is close to the 355.
The volume of those orders are way too minuscule that in order to actually sell 10 BTC you have to cover all orders till the highlighted row.
And the price you actually will get while selling your 10 BTC will be not the 355 but an average between all orders which you fulfill including that with the one which is highlighted with the price 10 USD/BTC. But of course you will fulfill it only partially to add the difference from all preceding fulfilled orders which will sum up to 3.1btc. Thus the difference will be 12.8 - 3.1 = 9.7btc
So if you sell all 10BTC the most part of your sell order 9.7 will be sold at the 10 USD/BTC price.

The same logic can be applied to the Ask side.

As to your question from the screenshot of the Ask side we can confirm that there is not error in data and calculation of the price in the arbitrage chart on you screenshot.

And thus we can deduct that this price is what it is in the order book.
In general this situation can be characterized as low liquidity. Why some exchanges has different liquidity this is very specific question and there can be a lot of different answers.
Usually low liquidity is caused by difficulties with deposit/withdrawal of fiat currencies. But the causes are not limited to just this.

Couple of questions:

Why is not Poloniex in the arbitrage tables?
Where is the list of exchange's full names? I don't know what "cbxUSD" is.

Does anyone still use http://bitcoin-analytics.com/. Is the service worth it, and is there a better service? Can this type of information be gathered in real time elsewhere for free?


Highly appreciated.

Now that Bitmain is signaling SegWit on LTC, they need to do the same for BTC
