Bitcoin Forum

I've created a simple charting tool for the markets:

http://bitcoincharts.com (Javascript required)

This is very nice, thank you. I particularly appreciate the "log scale" option.

cool!

Can you show on the your page several diagrams in one picture? With the different units on the Y axis?

All currencies such as USD, EUR and RUB are strong enough relative to each other, and such information may allow to reduce "turbulence" in the bitcoin markets visually uniting them

And... Where Rubles?! :(

I've already though about making a special chart with all currencies.

Where can I get trade history for rubles? (timestamp, price, volume)

Of course!
https://btcex.com/site/deals - directly from DB, please do not ask it too frequently

would be great if all currencies had the same scale.

oh and btw, it isnt MtGox PayPalUSD anymore, its MtGox LR USD

What timezone is the timestamp?

UTC

If you logged in into btcex.com and open this link timestamp are in time zone from your profile. But if this link opened by wget you get UTC

btcex RUB added :)

you are a master!
Now I have the proper tools for the Bitcoin technical analysis!
thanks

Finally some really clear charts.
Donation coming your way...

mtgox and btcex chartdata is updated every minute now

new features:
 
* show volume in currency rather than BTC
* compare two different markets in one chart (not to scale yet...)

Very very nice. Did you program the this or did you use some sort of library or program?

It's based around a charting library with a lot of PERL and python code to glue it to the markets.

Do you mind sharing the name of the charting library?

Oh I thought it was saying that somewhere in the chart.
It's ChartDirector from http://advsofteng.com/

Ok, so is a server side charting software. I have been looking exactly for this but made in client side, only asking the data to the server. I know there are JQuery libraries that make candlestick and the rest, but never found the whole thing.

It would be nice to see a BTC/gold chart... :)

BTC/difficulty chart would be interesting.

I don't know of any other BTC market that trades BTC for gold other than bcm PecunixGAU.

How would you draw such a chart?

Could you link in a Gold $ spot price from a different source? Then divide the BTC price in USD from MtGox by this Spot Gold price, automatically..?

One more question:
The "volume in currency" option does not work. Is there a way to make this work? thanks

Divide cents per bitcoin by the difficulty, and plot on a graph with a logarithmic Y axis.

Works fine here. Does it work if you click "Update" and does it say "Nov 08, 2010 - Daily - Volume in Currency" in the chart?

I'll consider it for the rewrite I'm currently working on.

Theoretically that could be done. Do you mean dividing all historic BTC/USD trades by the current spot price? What's the use for such a chart? Maybe I can add an input field for a custom scaling factor. Would that work?

Thanks for digging into it.

What I mean is a continuous chart of BTC/Gold spot (for the future, but ideally also historical since the start of BTC trading). As the dollar value of BTC will not really tell a lot longterm (the dollar will eventually disappear), the real expression of BTC value will be gold.

Hence a chart that looks at (at least daily) BTC/gold ratio will help a lot - to continously see what the real global purchasing power of BTC is.

example:

          BTC/USD        Gold/USD     miliBTC/Gold (=BTC/Gold*1000)
Nov 1  0.17               1355          0.125461255
Nov 2  0.19               1357          0.140014738
Nov 3  0.21               1348          0.15578635
Nov 4  0.25               1387          0.180245133
Nov 5  0.29               1384          0.209537572
...
If you can extract the actual Gold/spot prices from a different financial source (yahoo, bloomberg, cnbc, etc.) you can generate this automatically every time frame.

Gold over $1400 now.

In your eye, Bernanke.

I'll try to find a good way to add such a feature to the new backend. Probably as an addon to the "All USD" chart.

great! thanks

General update peformance should be much improved now.

added a market overview page

another update: there are now individual sub-pages for every market that will be filled with further information soon

Latest trade information is hard to read. Change it to darker color.

Can you provide a screenshot (tcatm@gawab.com)? It should be black on white background.

One more plea..: Could you make the default exchange on the "charts" page the exchange with the highest volume?
Currently, bitcoin libertyreserve is the first one showing up, but almost has no trades at all over the past days and weeks.
thanks

Good idea! I'll fix that today. btw: you can click on the small charts on the markets page to get directly to the chart.

New feature: Order book display for bcm and mtgox.

@bitcoinex: Where can I found your order book? :)

Wow, it's looking very good.

The order books are great. You could make an option to group them by some increment to make it easier to digest though.

ffs, it's about time mtgox gives us all the data.

There doesn't appear to be a donate address anymore, is this on purpose?

I'll add such a feature within the next days.

I have enough bitcoins, they're better spend elsewhere :)

Okay, I'll have to find something else to do with them then :)

Again, very good looking and useful site.

For a quick fix I added quantization to 3 decimal places (4 for PecunixGAU).

Chart suggestion: total value of bitcoin economy measured in any currency versus time.

As we are in the most inflationary period, it would be nice to see this chart.

Do you have a good source of (daily) historic USD/$currency data?

I don't, but with the block generation dates you can calculate the number of total existent bitcoins at each moment in time.. then you need to multiply this value by the data you already have on the btc unit prices...

So, the only new data you would need to gather is the block generation dates... don't the block themselves have timestamps?

Yes. Here are the timestamps if you want to try that:

I think it's pointless. When will the free time of course we do it.

Also, btcex.com will display depth of the market.

upd: you can get btcex.com bid/ask by json: https://btcex.com/ticker.json

request: can you add graph of difficulty and time as one of currencies pair? To be able to compare it with prices

Bitcoincharts now shows complete orderbook for mtgox.

Wow, cool. Now I know where to put my longshot crash bids.

Your website looks awesome, I'm checking it regularly :)! I also like that you've added some general bitcoin network related infos, helps keeping track of how dynamic the coin generation is. Would you mind adding graphs for those pieces of network related information over time, too? Some BTC are on the way anyway. Thanks for your effort so far and for sharing it!

Cheers, T_X

Thanks for the donation(s)!

@bitcoinex: I'll add your orderbooks soon.

Network graphs are on my todo. Currently busy with another interesting bitcoin project that's close to release.

bump!

LOVE the website. Is there any way you could add an option to change the timezone please?

+1

Do you still own this site?
If so, how do you know that the data from OKCoin is real and true?

It seems that it's probably more fake than MtGox data ever was!

Is OkCoin funding this site, or have some other influence over it?

Why is a shady, unaudited site, with unrealistic volume data presented as the biggest exchange in the world?
This is another MtGox disaster in the making. With me or anyone who asks me about it, BitcoinCharts has lost all credibility by adding OKCoin data.

Just out of curiosity, did you (owner at bitcoincharts if still there) receive any message from Huobi the day they went to 10.000?
Because bitcoinwisdom showed and then deleted the spike.
