For example, if you buy first-hand sugar, and then you want to close your position, but you only close your position second-hand, this will fail, because you can only close your position at most. At this time, the quantity you entrust is greater than the quantity you can close.

Another problem is that you may confuse liquidation with present.

For example, you bought a hand yesterday and bought another hand today. If it's an order from Shanghai, you want to make a deal together today. If two positions are closed, although the number of positions that can be closed is two, because one of them was opened today, it will be displayed in individual software that the entrusted number is greater than the number that can be closed.

It must be noted that it is individual, not all companies are the same.

This simple question is the same in eighty examples.
