Awesome

//but one suggest, Can you make it update faster, like 1 update per sec, just like clarkmoody?
MtGox is mixed realtime and http, I'm quite sure the speed is the same as clarkmoody and more stable.
BTC-e and Bitstamp only have http API, the frequence is about 5 seconds. 10 seconds for trades, 10 seconds for ticker and 15 seconds for depth. You must be have seen the change time is often large than 15 seconds, because no new trades received and depth is not changed. if BTC-e doesn't change in last 5 minutes, the Change will be 300 seconds though the data is up to date.
and in the back of server, the it will wait 1.5 seconds between each API request, for BTC-e so the minimum frequence is 1.5 * 6 ( ticker, depth, trades of LTC/BTC, LTC/USD) about 9 seconds, Bitstamp is 1.5 * 3(ticker, depth, trades of BTC/USD) = 4.5 seconds
so the frequence less than currently setting is not worth enough.
