After investigation, it has been confirmed that the account losses were caused by EA trading and are unrelated to the platform.

The EA placed 21 consecutive orders resulting in a loss of $600. It did not follow the rule of settling one order at a time with a lot size of 0.01. After contacting the customer service manager to confirm that there would be no margin call, the EA placed 21 orders within one minute, and then the group notified that the EA was out of control and distorted. A few minutes later, all 21 orders suffered losses simultaneously. I applied for compensation to the trading account 300378, where the transaction records can be checked. At 15:00 Beijing time, I was notified to stop the EA, but it was still placing orders automatically. Around 20:00, I changed the password of the trading account, but there were still 2 orders placed by the EA. Currently, there is still a loss of over $200 in the position of more than $450.
