Service updated.Some small improvements and were added other cryptocurrencies : IxCoin, I0Coin,SolidCoin. Due to the fact that currency APIs doesn't supports WebSockets, data updated every 5 minutes, but you can also do this manually by pressing "Update" button.
You can set minimum and maximum margins for depth chart by pressing "Settings" button and installing "min depth chart price" and "max depth chart price" values .
cool... by the way your instructions for websockets in Opera say "restart opera" but I didn't need to... I just refreshed your site.
Some previous opera versions needed to be restarted, so I'll keep this in instruction.
