Hey guys/gals, what backtesting website have y'all found the best? Preferably free if there is one but can be paid if free isn't an option.
​
I have tried to use AI and coding, however, for my strategy I am basing strikes off delta and not fixed percentage. Also, it requires take profit actions and AI has a hard time figuring out what percent the stock needs to move across a given timeline to reach a take profit.
​
I'm looking to run Iron Condors, Put Credit Spreads, and BWB strats.
​
Thanks for any advice y'all may have!
