Hello Charbel,
Glad to hear from you. Well, actually not.
When you add a win/loss ratio in EA Studio what you see is 0.5. This is the default and it means 50% winning trades. Or we can say 5 out of 10 are winning. If you want to have 90%, you need to put 0.9. This way you will have 9 out of 10.
But when you place 9 as a value, you are asking for 900% :) That is why you couldn’t generate strategies.
Actually 0.9 is still a high requirement, but give it a try.
Cheers,
Petko A
