hi all, i'm new to the automated / strategy trading, and i'd like to try using it. i am a software developer, so i'm perfectly fine with writing code to do backtesting. it looks like tradestation is one of the most feature-rich, but it comes with a cost of at least $100 / month if you want to do the backtesting. can anyone recommend a cheaper software that can be programmed to do any type of strategy trading, that can be back-tested on historical quotes? many thanks!
