Hey Michal.
I am sorry to hear from another person who was scammed.
I think you hit on very bad scammers. If the negative trades are just disappearing that means only one thing – there is no trading at all, you don’t have an actual trading account and trades opening. Those companies are just simulating some platform that has nothing to do with the real market.
Give it a try to ask for a withdrawal, but I don’t think they will do that. But of course, you have to try.
And the most important thing: WHATEVER THEY SAY, DON’T DEPOSIT MORE.
