Just an update to this topic: I started using more the consecutive losses acceptance criteria. I went down to 5 and the strategies I get are really awesome. I use it as well to remove the EAs from my live account. If they make more than 5 consecutive losses, I remove them.
And it makes a lot of sense because if we create an EA following one thing when this thing is broken or comes not true, it means the strategy was over-optimized for that criteria. Correct me if I am wrong Petko.
