Hello Centcel,
the best thing to do is to start with small criteria, not strict. With the time when you collect more bars, you will be able to increase it. For example, try to make stricter the criteria every new month. Increase the Number of Trades from 300 to 320, 340..every new month. Because with every new month you will have more bars. It worked for me before…
What I do now is to create many EAs, and after that filter them in the collection. Not looking so much to make it strict.
