@Viktor-I took some advice from Petko and then formulated my own rules for demo. I put a lot of effort on the generation of EAs…meaning my acceptance criteria is very strict. Once this is done, I demo test with this criteria before going live:
Min 2 week trading time period
Min 10 open and closed trades
Min 70% winning percentage
I have 4 live EAs in my account right now and I am demo testing 96 EAs. The 4 EAs that I have live, I keep them in demo as well just to maintain performance history.
