I do love this site, I like being able to see the MacD even if I can't always understand it. I can't understand why when I click to see the weekly view the graph becomes very short. Is this because the site is still new? can it include some more historical data? thanks
Mt.Gox, Bitstamp, Crypto-Trade has full historical data.
BTC-e and others doesn't have the API for full historical trades, so only have partial data.
