Simply put, as long as your rights and interests are greater than your position margin, you will not be closed. At present, there are 27,550 copper hands, margin 15%, and about 20,660 traders, with no fluctuation at the lowest.

Counting the price limit will be even greater. According to the ratio of 5%, 7% and 9%, it will cost 30,000 to bear the first price limit, and so on, and it will cost 50,000 to bear the third price limit. This possibility is relatively small.

To make a compromise, 30,000 yuan is more appropriate.
