SaxoBank automatically closes opened position at night?

I am using their order book tool and found an interesting regularity.

Every day at 2-3 am, lots of opened positions are closing automatically.
For example:


Can anyone, maybe who traded at saxo, explain me what is that?
What is the reason of that decrease in amount of opened positions?

Thanks.

saxo does not close your trades at night for sure, can't tell wtf the above means.

Thanks, but it's not the answer i am looking for.

Nobody knows?

It would be better, if SB could give you an answer for allowing such actions...
