Wow....  awsome work.    as google would say,  "For the ubercool interactive charts, you need to install the Adobe Flash Player"

but you did the ubercool without flash.   

bits are going to the fund!!

Your chart is by far the most happening for web-based bitcoin data.

If Campbx pans out as a trading exchange, do you think a chart for them would be warranted?

I sent my btc donation for your "Wild Turkey" fund.

I would ask all who appreciate Cowboys good work to do the same. (AA counseling to follow shortly)   



Cheers,
Stew

I honestly think he should just be the resource for exchanges to plot their data. (And collect a bit of their fees for his trouble.) The features and design are just that good. Really like how he has a way to communicating updates - something the exchanges should do by default.

[Alphonso Bedoya]

Thanks for the ongoing updates to the charts. They are very useful and keep improving without slowing down, so I am sending another fragment of a decimation of a digital currency to the whiskey fund. Well deserved.

[Trader Steve]

Great charts! Sending over some BTC to your "whiskey fund".

Hi comboy, thanks for the great tool, sent some fractional coin your way already.  It looks great, and I think there's a good chance you could get an exchange to license your graphs for use on their site.

I'd like to offer a bounty of a 1.5 coins if you add, on the bottom graph, a way to view how volume has changed over not just the past 10 minutes, but also over 30 minutes, 1 hour, 2 hours, 4 hours, and 8 hours.  Maybe another little series of clickable regions like you do with "10m | 1h | 3h | 12h | 24h | 3d | 7d"?  I think it would be very useful to be able to click around and see when bid & sell "walls" appear & disappear.  Right now, if you aren't watching in the 10 minute window, it's impossible to see what the bid/ask spread graph looked like more than 10 minutes ago.

Another nice-to-have feature would be a way to switch the bottom volume bar graph between linear and log scale, with the graph auto-scaled like the top graph when in linear mode.

Anyway, great tool, looking forward to watching it grow!

Looks great. Needs much higher polling interval IMO.

[Randall Flagg]

nice ! finally a use for my 15" old display like you, keep that resolution!

[Acidka]

Looks great. Needs much higher polling interval IMO.

No "stupid-polling" there. It's uses websockets or long-polling as fallback, it means that any data is transfering only then server got fresh "numbers", it lowers server load and traffic waste much. So numbers at "Last change" in the corner just saying how many seconds data remains the same not the time from last "poll".

P.S: sorry for my bad English.

Thanks for explaining that for me.

I'm working on some bugfixes and optimizations before adding more features. Something to keep you busy in the meantime: http://bitcoinity.org/markets/hardcore (it's quite useless, just for fun).

I've wanted to add bitcoin7 but they don't seem to provide volume for the latest trades (or anywhere else for that matter, so I have no idea based on what some people claim it to be one of the biggest exchanges).

Updates coming soon.

[comboy]

Good news everyone!

• some people are buying me whiskey and I really like it, thank you!
• in top right you should now see preferences link, only some basic ones for now
• you can choose time span for which depth changes bars are shown
• new exchanges coming:
  bitomat: http://bitcoinity.org/markets?exchange=bitomat&currency=PLN&span=3h
  britcoin: http://bitcoinity.org/markets?exchange=britcoin&currency=GBP&span=3h
  and even more experimental than the others: http://bitcoinity.org/markets?exchange=dotbit&currency=NMC&span=3h
  (if you read this soon after it was posted, charts are likely to be quite empty)
  
• bugreports welcome, ideas welcome

These charts are amazing.

[old_engineer]

The changes look greatl!  1.2 btc on their way, still hoping to see multi-hour volume changes.

Oh, and another feature might be to allow users to filter out trades worth <1 btc from the trade ticker on the right.  Often times a number of 0.1 btc trades will scroll the big trades off the screen, yet the fractional bitcoin trades will never move the market, they're just noise.

Great Work! BTC on their way

I set my preferences to .00 on my HTC but it still seems to load randomly with .000 even though I cleared the cache

Thanks for info, should be fixed now.

Thanks l'll try to think of something, but I would have to organize it in some other way. Currently I'm just pushing all depth changes that were done during that time to your browser, and then it smoothly scrolls over it, so that always last X minutes are displayed on the chart. But for 12h that's too much data (even 1h for mtgox is quite a lot)

Added (available in preferences).

edit: and I fixed small bug with switching timespans when having different exchanges opened in multiple tabs

Wow nice charts! Comboy, what technology is it based on, what programming language do you use?

Data is pushed to you using websocket, with fallback to flash and long polling. Server side is in ruby + a little bit of node.js. And of course whole bunch of my crappy js & css to display it somehow. Mtgox data is live because they provide websocket, for all other exchanges I need to query them periodically (every 10-60s, which seems quite ok, given how often trades are happening there)

+1 for spelling my nickname correctly
