Hello,i am a trader who has been trading in the forex market for 9 years.i had xauusd and open positions on 03/12/2023. there were 0.30 lot sales and 0.20 lot purchases available on the night of 03/12/2023, XAUUSD appreciated very aggressively overnight and I only have 300 USD of equity left.i added 0.10 lot purchases from 2108.55 and had 0.30 sales and 0.30 purchases, and although I balanced my account 100%, they played with the spread difference and exhausted my margin, they started closing my transactions automatically around 2145.As a result, it is very clear that they are playing with a SPREAD with $300 equity in my account, and therefore my transactions are closed. At the same time, there were 4 other accounts connected to this account ( WITH COPY TRADE). in other words, by performing a trick, they damaged 5 accounts at the same time.
