My account number is 307952, order number is 27791079, and I placed an order at 23:34:39 on September 29, 2022 at 1.70790 for 1 lot in pound Australia. When the time arrives at 00:05:17, the platform spread increases by about 2,000 points for no reason. This All platforms in the time market are at around 1.71000 pounds and Australia, and the GMi platform maliciously expanded my order spread to 1.72152, resulting in a liquidation.
