At the beginning of the account is empty, I want to empty list and multiple lists at the same time, set the direction to close-sell and then empty lists; run the retry, report ERR_INVALID_POSITION error. What is the reason?
The bride too.I'm not going to open two accounts, I'm not going to open one.
The Little DreamBITMEX cannot simultaneously hold more than one position under one contract. In addition, closesell is a flat stock, buying operation.
