I'm happy to announce that http://www.bitcoinmonitor.com is now online! Transactions, blocks and trades on (currently only) Mt. Gox are plotted on a chart there. The website refreshes automatically as soon as new data is available. Enjoy! :-)

Very nice. A good example of a web page that does one thing, and does it well.

I would like the vertical axis to be logarithmic. This would give more interesting detail at the bottom of the chart, without losing the data points at the top of the chart.

Thx for the feedback! I played around with a logarithmic scale for a little while, but wasn't really happy with it. But you are right.. right now once in a while someone moves huge amounts of Bitcoins and blows the chart apart. =) .. I might look into the logarithmic option again at some point.

I really like this, sent a tip. Be nice to be able to see a larger window of time. FYI the cluster of transactions on the hour is the mining pool paying out.

Yes, nice suggestion. I might look into implementing something like that at some point.

I like your service and tested it by sending a tip as suggested Smiley. But missing slider and zoom. Also better precision would be nice. Last mtgox trade was at 0.896, but graph displayed it as 0.9.

mean, standard deviation, etc don't supply much info on your difficulty vs time charts.   slope of the moving average line is more meaningful

Thx for all your feedback, tips and suggestions! Many of them are on my TODO list.

Integrating more markets is probably the next thing I will be focusing on. Mt. Gox was just an easy and sensible first pick. However, before I include more markets, I would like to get in touch with the people running them about the best technique of doing so. Since I'm providing live-data on the website, the whole thing depends on having recent data available. Many markets only provide their trades over a webservice, which I would need to poll. I'm currently polling Mt. Gox at a rate of once every minute (@mtgox: I hope that is ok), but the software engineer in me finds that somewhat inelegant.

I noticed that jgarzik has done some work on a streaming real-time market data server already (http://bitcointalk.org/index.php?topic=2519.msg34154#msg34154). So I will see to what extend I can interface with that. Maybe it's a good opportunity to standardize on some format for trade data and set up streaming servers of this sort at the various markets. I would assume, that they are interested in providing their trade data in the most convenient form and also reduce traffic from polling.

Another option I'm thinking about: I can't promise anything yet, but I might set up a gateway for those markets, who don't want to run a streaming server of this form. I can see how some markets might not want to bother with the effort, as it doesn't necessarily integrate easily into web applications. So I might end up polling them, but then provide the data over a streaming server. This way others, interested in the (then-sort-of) real-time data, wouldn't need to poll.

Well, those are my thoughts so far on real-time market data. :-)

Sure it's a memory leak? Could be a sort of garbage collection, just like the JVM.

Yes, could be. Might be a chrome bug I guess, but as the page actually crashes I am a bit suspicious.

The client code was a little bit wasteful in how many old data points it would keep in memory. I just deployed a new version which should free memory somewhat more aggressive. Hopefully this helps!

The Bitcoin Monitor now switched to a logarithmic scale, which is definitely better suited. A bug in the graph library I am using didn't allow me to switch sooner, but that is fixed now. In the meantime more market data has been added as well. Now the markets Mt. Gox, Bitcoin Central, BTCex.com and Bitcoin Market are tracked.

Thank you.  This is an excellent tool and the log scale looks great.

Great ticker! It's mesmerizing to watch the transactions slide by.
I would like to second the request for adjustable axes (i.e. be able to set the window of time and volume displayed).

Thanks for your work.

Just come across this and think its great!

One suggestion.. history of say 30 minuets rather than 15?

Has the above helped you? Consider buying my a coffee Smiley BTC: 18AcGgzE6CBVzTphKFVdvHEzQctCG2wCi6 LTC: LP3NHLsAUEjGPDteDQLjviZRPeyTmvqXAH DVC: 1Cvf4NNwFoVB5wnBwoFEU7dwrSXPFK7rLR
