The prepayment ratio is still between 120% and 130% for no reason. The position has been liquidated for no reason. The explanation is that you have liquidated the position. Ask him why the position has been wiped out, saying that you didn't lock it, and now he has not given anything. Explain that the 120%-130% advance payment ratio has been liquidated, and the forced liquidation is actually 40% of the paid ratio, and the liquidation has not sent me a margin call notice until today? The customer service has been procrastinating and has never responded.
