@George-Oh, things like the R-squared being used when I’m generating strategies. After going through all the update videos that Petko produced, it helped a lot with my generating better strategies (better win/loss percentage, better equity lines, better max stagnation and max drawdown, etc.) Oh, I started using the In sample and Out of Sample along with the complete backtest in the acceptance criteria like Petko taught in his videos, to also help with generating better strategies.
