Personal opinion: Locking positions and stop loss are completely different ways. Locking positions is both a loss lock and a profit lock, which cannot be equated with stop loss, nor can it be equated with the treatment of stop loss orders.

In terms of processing difficulty, lock-unlock is much higher than stop loss, especially loss lock.

Personally, if it can be unlocked perfectly, is it necessary to lock the warehouse? -In a volatile market, two-way positions not only affect judgment, but also reduce the number of profitable positions; In the trend market, you may miss a wave of market in order to save dozens of points.

Considering the opportunity cost, it is not worth the loss. It is better to stop loss directly before. On the one hand, the psychological burden is reduced, on the other hand, there is no need to take a two-way position to influence judgment.
