My trading account is 680****. Order number: 2372951. I traded 1.22 lots of gold at platform time 2026.1.23 23:55:49. The quoted price for the order was 4988, and the execution price was 4985.84 (3 pips slippage). The platform closed the position at 23:58:50. The closing price was 4995.02 (7 pips slippage). The platform's slippage is too outrageous. In just one second, the difference between execution and closing was 10 pips. The first time I emailed to negotiate, they asked me to provide information. After I provided the funds, the platform never responded to me. Such severe slippage is the platform's fault, and the unwillingness to resolve the issue also lies with the platform.
