Hey Mourad,
I understand what you are talking about but we and other traders, have passed challenges with our EAs so that means they actually aren’t bad but they are pretty much functional.
As I mentioned, you need to first test them in demo before setting them in a live account or challenge. That is because you need to see how they are working, get comfortable with them and then set them on live account.
If you check the following table, you will see that there are actually results: https://eatradingacademy.com/premium-robots/ftmo-robot/
You need to follow a strategy to get results!
Also, keep in mind that the market conditions also are not good at the moment and that can also cause losses.
Kind Regards,
Nikos
