Backtesting Software

Hi everyone, I would like to resurrect one question which was asked couple of years ago, I guess this situation changed a lot till today.

So, for all those which backtest their ideas before committing real money to them, can I ask what methods & software you use to perform this? I am interested in learning drawbacks of various available software and see if there is room for improvement.
Thanks :clap:
