There are usually three ways to unlock:

Oscillating Market Solution: When the market is in an oscillating state and the trend is about to change direction, close the profitable positions and keep the losing positions. If the price subsequently returns to a certain extent, the losing positions will naturally be relieved.

One-sided Market Solution: In a one-sided market, add new positions in the direction of the trend's development. When the price moves along the trend to a suitable position, use the new profitable positions along with the existing profitable positions to bring the losing positions back to profit, thereby achieving unlocking.

Increased Position Solution: This method evolved from the first approach. While closing the profitable positions, new positions are added in the direction of the losing positions. The advantage of this approach is that as long as the price rebounds halfway, the lock can be released; if the price continues to pull back, it can also achieve profit before exiting.
