Nice one, it worked.

Thanks Bzzard.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

I use chromium and also had to empty the disk cache before I could see the new version.

Use price and time range sliders:


Looks like orderbook on current version is stable.
Bad news is that reconnecting don't work so well and I'm out of ideas on this topic
(I've enabled auto-restart, but I can't find data on how to restart manually on sicket.io)

Can we get a way to remove that giant price at the top of the chart and a way to have it auto-refresh?  It doesn't seem to be refreshing for me. 

But the big price thing needs be configurable.

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

You can control size of big price with:


When it comes to refresh - I have no idea how to improve socket.io beside what I've done so far.

If you want to manually refresh then go to http://109.109.243.218/
Let's say couple times on minute will be good on me Wink


I'm working now on auto-refresh by normal http, every 30sec socket silence.
Possible this will be done today but that depends when I get sleepy Wink

Wow thanks, I didn't even notice that... perfect!

The auto refresh seems to be working now... maybe it was my connection.  Nice work!

I don't see the trace lines anymore.  I'm lost without those little guys.

Couple days and ghost lines will be back.

Bid/ask change on time move is in my plans, but I can't tell when you will see this.

Can you display the current number of users connected ala Mt. Gox live? A history of this would also be useful...

I don't think I can get access to this data.

Please don't use http://109.109.243.218/ for the next couple hours - there's something wrong.

I just moved domain to new server. In next 24h you will be redirected to http://109.109.243.218/  then normal domain should work.

I added new "HTTP updater" - this will be enabled when there's no live data from MtGox. Updater will load recent changes every 50 seconds. I know 50 seconds is a lot of time Wink  but I must check first how server handle this - then it will likely lower this timeout.

Next step will be adding some kind of live data from my server.
Other exchanges will also get live data (10 sec max delay) in future.

Cool. A fallback updater, that's how it's done!

Good job! Smiley

Great service!  Do you have a donation address?  I had a 20 btc bank error in my favor, and I'll donate the proceeds to you.

For what it's worth, I'd love to see a slider to view the historical order book. Were I you, I'd implement this by saving the order book to a table as a set of points, one datapoint per penny, to reduce storage and data transfer requirements.  This would result in 1000 datapoints between $0.01 and $10.00, and saved every 1 minute would be 1000 points * 4 bytes (order book quantity) * 7200 minutes = 29 megabytes/day, 10 gigabytes per year.  Seems a reasonable start.  Better yet would be to store and send to client in a compressed format given the lack of data randomness. Historical charts more than, say, 24 hours in the past could be a premium service you could offer for 0.5 btc per month.  Keep it in the $2-$3 USD range, and you'll get a few dozen subscribers that might help you break even on bandwidth costs.  My 2 bitcents.
