When I woke up I found two of my orders closed. Did anyone experience that?

When I woke up I found my orders closed. I definitely did not close them because I was asleep.

Did anyone face the same issue with DMT5 trading?

It was not a margin call because I have over 33000% margin level. There was more than enough balance in my account.

The orders were closed at precisely 01:30 am. That is weird.

Here are the trade details
