Judging from the few info provided it seems your style of trading has the tendency to scale into losing positions and you also seem to avoid to close a position with a loss.
While you might have found a way to make this work for you, generally speaking, that is a very dangerous and bad habit also applied by most of the fraudster signals going after inexperienced traders money.
As Darwinex legally is the money manager behind all Darwins they have to make sure that appropriate risk management is applied to the Darwins. I am afraid if this system doesn't work for you, you will need to go the signal service / PAMM route with all the disadvantages/advantages involved.
The risk manager has been discussed since the very beginning in multiple threads. While it has already been improved quite a bit, I do agree that it has certain drawbacks and could be further improved. Still, it's a good compromise to avoid complete account crashes by Darwin providers going crazy.
Your rant is excessive and inappropriate IMO.
