I am still evaluating the update/crash issue but need to ask for one feature (important in my opinion):

Please add a function to import historical currency data.
It shouldn be any legal problem as this are publicly available.

For users like me which dont run STB for 24h/day it would be much help. (I am not arguing - I know that trading robot should run 24/7 but in given circumstances lack of historical data is PITA).

It is possible - I found BTC trading bot for Chrome browser which initialize itself and download historical data from MtGox.
