Hey Gregor,
I see what you mean but please keep in mind that any robot that you will try, cannot bring profits all the time. It’s the same case with these robots, they are winning and losing periods.
It’s good that you are testing them in demo as this is what we always recommend before putting the robots in a real account and the reason for that is so that you can test different setups that might be profitable for you.
What I would say here is to keep testing the robots until you have found a good setup that is profitable.
Kind Regards,
Nikos
