Locking a position means that once the order enters the market, once it falls below the stop loss point, it is not a timely stop loss, but a reverse order is opened backhand, which is equivalent to holding multiple orders and empty orders at the same time, so that no matter how the market outlook fluctuates, the loss space is locked and the loss will not continue to increase.

Since the warehouse is locked, it involves the problem of how to unlock it later.

The general idea is to wait for the price to reach a low level, and then wait for the rebound thanks to less losses, or even make money, so that both orders are profitable, as if there is no loss. Many novice traders especially like to use lock positions.
