That site is pretty much a joke. Sure, all of their computer generated buys and sells are on the money, BUT, you would be in much better shape if they would have left the Feb. BUY at .0004 alone and now you would still be in with a double at .0008 but you would have "8" less commission charges from all the additional trades, and taxes, etc. etc.!!!
Some swear by that site, for me it's like delayed quotes, or it seems like it anyway.
