Boyyyy, you are speaking nothing but the truth.
I backtested 3 months and found that the signals are quite good, but the problem is the losses are tough to overcome. For 1 loss, you need 4 winners to break even. They do have settings where you can set max SL and TP targets. It's also possible to activate a setting where additional contracts are automatically added to the next trade after a loss. But that that could put you even deeper in the hole.
Today (SIM) started with a loss. So - $500, then 5 winners back to back leading to a profit of $100. Next one was a loser so you are $430 back in red, despite having way more winners than losers. Tough....
I am super curious about other ATM settings people may be using. But mostly I would like to understand the strategy and thought behind it.
