A problem with MCFX is that it can't store history data on your harddrive. So whenever you start the program or change timeframe it has to download everyhing again from FXCM. That makes it completely useless for intraday trading IMO.
I just downloaded a trial of RightEdge. It's a charting and backtesting package. Version 1.1 supposed to support autotrading with Oanda if you have an API account.
It's currently in beta but worth checking out.
