After a round of operation, the platform asked me to add position, claiming that my data was unmatched. After doing so, the I placed order correctly in round 2. But a mistake in the final round caused the unmatched data. I was asked to make up for the amount of order placing and the P&L margin! But I failed to make withdrawal due to wrong bank information. The service asked me to pay 35% margin, i.e., 180 thousand yuan or so. So I applied for the 25% margin, 130 thousand yuan. I got a real “whose hoops” over here.
