I said it is off topic, because my question was different. Again, is it normal for a broker to wait that much Bellow the margin limit before closing a position?

My other broker has a counter which you can monitor all the time, telling you exactly when you will receive margin call. It goes from 0 to 130%. They dont wait or check or whatever NT pretend they are doing. If your margin limit is 1000 and your total account balance goes bellow that with even 1 USD, all your positions are automatically closed. These are the rules, this is written in the contract. And it is just 2 rows of code, so easy, there is no explanation why NT does not have it.

The NT Brokerage behavior makes me think they just play against you in situations like this, based on their decision. Nobody doubts they have good traders in their team, right?
