The locking function can indeed temporarily prevent the loss from expanding, but when it comes to unlocking, the problem comes. Every unlocking is a real guessing behavior, which also determines that the long-term result of the transaction is failure! After locking positions, most traders are influenced by one-way thinking, and constantly hope that the top and bottom will appear, thus affecting the overall judgment and no longer making an objective understanding of the market. After each lock, you can look at the net account value. Locking a loss position is equivalent to a stop loss, and you will be induced to continue to make mistakes in this wrong transaction. The correct way to use the lock position: 1) When the market turnover is light and it is judged that the interval fluctuates, the same amount of orders can be issued at any position in the interval at the same time. When approaching the critical point, you can close the profit sheet and set a stop loss for the other sheet, waiting for the price to return to the other end of the range. 2) When you make a profit, you think that the price has reached the top or bottom, and you want to continue to track the transaction, reverse the operation, and intentionally lock the profit part for the convenience of observation and tracking. Once the market reverses, you can deal with it in time. Because the situation at that time was profitable, you can make a new bet with part of the already profitable, and it is easy to make an objective judgment. This is the so-called benign trading mentality cycle.

For the correct use of lock warehouse, you should have certain practical experience and analytical ability, which is not something that ordinary novices can master. For beginners, don't use it at will unless there is a good teacher's guidance. The only magic weapon to survive in this market for a long time is to abide by trading discipline!
