Hello Michael,
Nice topic and question! I have been using EA Studio for even longer and I can say it is really not easy to follow the results. We create many EAs, and trade many assets, it is hard to keep it up.
What I personally do is to look at the long and the short term performance. In FXBlue I change the dates looking at the last quarter of the year and the last 2 weeks. If I follow the performance of EAs on Demo and live I want to know how they do in the longer term and at the same time how they go in the recent market. This method Petko shared with me in 1:1 class and it works for me.
So if I look at Profit Factor 1,2, I would like to use in my live the EAs on Demo that show 1,2 profit factor for the last 3 months and as well for the last 2 weeks.
