On Friday morning, when opening long positions in gold, whether it was 1 lot or more than 10 lots, the price was at least 2 points higher than the real-time price, and sometimes more than 5 points higher, which was clearly malicious manipulation. This made it difficult for long positions to profit or result in small losses. The opening price was no higher than 5375, but the actual execution price was 5382.29, with a delay of more than 0.3 seconds and frequent disconnections. They even maliciously opened positions for me (the execution time was earlier than the opening time). Finally, when the liquidation line was reached, they deliberately didn't force liquidation until the account (21890043) net value became negative before finally liquidating.
