Does anyone know of any platform for FX or futures that allows for backtesting? I'm looking more on the FX side but don't mind futures. Data isn't too hard to find. Several sources, QT being the best I've seen yet, but hey if anyone has any suggestions, please share. The hard part is finding a platform that allows backtesting. The only one I've seen (for FX anyways), is the one at aaronFX.com. Haven't been able to find anything for futures. Any help is appreciated. The keyword in all this is FREE.
