Hi, what kind of profit factor should I target for my EA on 6 month optimization period? I don't want to over-optimize it... I currently have about 3.0 of profit factor and I wonder if I should work harder until I can get let's say 4 or 5... but then wouldn't it be simply curve fitting the EA?
I consider maximum profit factor of 2 for a robust EA. Value too high either means you over optimized it or using some kind of scammer's trick, eg. martingale, grid.
Yes you are right, over optimization = curve fitting.
