Looking for a (keyword) free backtesting INTRADAY platform for either stocks, futures, or FX(if that's possible). Quality/ease of use doesn't really matter, I understand I'd be looking at mainly demos or shareware versions with non full operational capability, but as long as it can backtest intraday, good enough for me. Search has yielded these daytrading demo platforms, but I'm looking more towards backtesting than paper trading. http://www.elitetrader.com/vb/showthread.php?s=&threadid=69615&perpage=6&pagenumber=2 Historical data I have used search to come up with some results, but would like your opinions on good (keyword again) free historical intraday data. So far seems like opentick/qcharts for stocks, several russian/swiss sites for FX, and nothing I could find for futures.
