I would contact an attorney to subpoena a statement of those 5 losing trades (if any) to prove or disprove that the orders actually went to market via liquidity provider or just parked on their demo server where the "hypothetical losses" were simulated while they and burglarized your account(s).
Then, I would register a complaint with CYSEC and request arbitration. If that fails then I would continue to seek justice within the jurisdiction of the appropriate courts.
And no matter what never never never give up.
So you gave them the money yourself basically. They are only guilty with very aggressive marketing. And, maybe, their software is rigged but we cannot know for sure.
No guilty
