After verification, it is confirmed that the slippage is not an issue with the platform. Other clients were trading normally during the same period and did not experience such issues. It appears to be a network problem on the client's side.

The slippage is serious. At the beginning, the slippage is acceptable at 20 to 30 pips. But the slippage becomes more serious, at 50 to 70 pips. The slippage of gold can exceed 7 US dollars, and after the slippage, the market is stuck for three minutes. There is a video to prove it. I placed orders normally. In communication, the platform was arrogant. I showed them the video but they found various reasons not to deal with it.
