On the evening of May 3, 2024, the non-agricultural market situation, Doo Prime's service connection was not normal. I placed a long gold order at about 9.31 minutes after the non-agricultural data was released. The server froze one minute later, and MT4 It showed that the disk was not moving, and the connection was successful only after about 9.34 minutes. As a result, my long position of 0.45 lots was liquidated, resulting in a loss of US$915. Later, I pulled up the MT4 transaction log, which showed that after I successfully placed the order, there was a problem with the server. It showed that the connection was successful after several times, and then the connection was lost immediately. After communicating with the platform’s customer service, I asked the platform to compensate for my trading losses. The platform did not admit that there was a problem with the service and did not assume responsibility.
