I have been heavily optimizing my EA with genetic algorithm checked for faster speed. I found some excellent setting combinations but when I try to combine these with other settings those particular sets seem to be avoided by the optimization results! I have even re optimized with the settings I know work well and they have been left out of my report. It's almost as if meta trader recognizes those results are very good and therefore doesn't want to show me them! The only way to get the same results again is to run an individual test on that combination. I have cleared the tester cache before every test which did not make a difference.
Any ideas what is going on? It is very frustrating because it takes forever to find a good combination and I feel many good combinations are being over looked by mt4 for whatever reason.
