It should be that multiple orders and empty orders of the same price are issued at the same time. If the transaction is completed, your transaction is only a fee loss, and the order has been locked. If you don't raise the margin, you won't suddenly open a position, because there are losses and profits at the same time, and price fluctuations have no effect. However, once the margin is raised, your account will suddenly open only if the funds are insufficient to pay the margin.
