Spot nickel backhand opening refers to opening the same position in the opposite direction after closing the position when the hand has already held a certain position. For example:

First, in the case of holding multiple orders, close multiple orders and open empty orders;

Second, in the case of holding an empty order, close the empty order and open more orders.

Third, the opening price is the buying price and the closing price is the selling price. Also pay attention to compulsory liquidation. Nickel is forced to close the position, because you don't have enough money to pay the deposit, so you will be forced to sell it. Only by continuing to invest money to earn enough margin can we avoid compulsory liquidation, so investors should pay attention to compulsory liquidation in the future.
