1, futures locking refers to the futures investors opening positions with the same number but opposite direction as the selected positions. No matter where the futures price moves (up or down) after locking, it will not increase or decrease the locked profit and loss.

2. For example, currently on 1 hand. Whether it is a profit or a loss now, opening an empty order in the opposite direction is a lock. After locking the warehouse, the total amount of funds in the account remains unchanged, and the subsequent market has nothing to do with you until it is unlocked, that is, a reverse order is closed.
