Hey Konrad,
Actually, the best approach is to first test on a demo and when you are comfortable enough, you can just go ahead and trade them on a challenge.
What we are basically doing also is that we check in the app to see if there is any more profitable robot than the ones we are trading currently. For example, let’s say that we have a USDJPY EA but on the first robots in the App, we see a different or one of the same pair but with different magic number, we just change the robot that is trading with the one that is on the top 3 or 5.
Hope this helps!
Let me know if you have any questions!
Kind Regards,
Nikos
