Irregularly exceeds the liquidation by 0.02 lots, lost 87 US dollars and lot size

A very inexplicable and unpleasant thing happened before the market closed in the early morning of last Saturday, that is, this platform closed my position. My account 330059290 is an old VIP account. VIP accounts will be liquidated at 10% from Monday to Friday, and positions below 100% will be liquidated on weekends. Now I explain that the 200% liquidation line for positions held on weekends. But even so, the margin of my VIP account 330059290 was 67% when it was not enforced at that time, and my order was every 0.02 lots, and closing 0.02 was enough to reach more than 200%; but strange things happened around 6 o'clock . I saw that my order was almost blown and closed by 0.05 lots! There is only 0.01 hand left for me, what is the difference between this and the explosion? I have always been in a locked position, and I only unlocked it on Friday night, so I didn't care about it anymore. Why did it have to be closed for me with only 0.01 lot left? And the margin reaches 351%? I called the platform at that time, and the man with the job number 8140 received me. He said that he was also very surprised why Heisei was like this. He said that he would report it on Monday, and then the relevant department would call me back. After emails and phone calls, the platform has not resolved the issue. The price at which it was liquidated was 1898.57, and the closing price of the platform was 1898.11. It is entirely possible to calculate whether it is reasonable to liquidate my 0.05 lot. I hereby appeal and hope that Huiyou will pay attention.
