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.

Thanks.

I buy BTC for CASH in the US. Message if you have > 25 BTC to sell.

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?
