Where I can backtest over some years intraday stock moves based on a screener, best or cheap ? Because I only know Trade-Ideas where I can do it, but it is only 3 months of data back, which is far too short. Else I know Portfolio123 website but that is only for swing and longterm holding and has no feature for trading at open and close on same day or any other intraday move I want to test (without coding from my side please). Which website can offer this best ? Which website can do this for cheap ? I just want to do some simple tests from some ideas. Thanks.
I can recommend https://www.quantconnect.com/ It has a bit of a learning curve to get used to their platform, but you can ask any AI to help you construct the JSON for the job description if it is too hairy.
