Sorry if my questions sounds elementary but how do u write software or purchase it for back testing,,,,,, ive been trading for 10 years and my trading style have completely transformed to fully systematic which i used to do back testing manually on excel, now that the position size has gotten big for me i need to access multiple market and the data i need back tested is beyond human capabilities,,, what iam trying to get at is where do i start when searching? i tried black testing software, back testing methods and all i got online was bunch of sales people that didnt understand what iam really after and data providers ... any input???
Thank you
Not sure what you would need in terms of back-testing software because I don't know what your trading rules are. Without giving away your exact system, what are your rules for buying and selling?
