I have been working with the EA Studio for some time now and I know my way around. I have been using the Reactor along with the Monte Carlo models to verify more stable and robust strategies. Keep in mind that I am having hard time with understanding some concepts. E.g. I have no clue what R squared is or does, what walk forward optimization is. I am new to this area and relatively new to forex, just 9 months around. So I am still learning, one step at a time.

My challenge right now is how do I determine that the sum of the EAs (I narrowed down to the 60 best) I gathered are going to be good for the next month or two? I understand that forex phases can change. I used 200 test simulations of monte carlo with strict acceptance criteria for my needs. What I did was to collect EAs with a very good Return/Drawdown, which have been profitable the last 6 months, and were stable and in profit the last 18 months. However I still believe that I am leaving this to luck. The market changes when major events occur or... whenever. I don't know when. I am new.

I checked here and saw that there are courses: https://eatradingacademy.com/courses/algorithmic-trading/

I am aware of the ultimate pack which exist but this is too expensive for me and I was happily surprised when I saw that  individual courses are available.

So I am thinking of taking a course or as many will help me with this challenge. Any idea which one will help me with my need? Or maybe any other information I have to be looking that will help?
