Locking is the reverse operation of the same number of hands in the original position. For example, if there are more than 5 lots in the account, then the lock order is the corresponding 5-lot empty order, so that the profit and loss of the account will not increase or decrease with the price fluctuation.

Lock warehouse is generally divided into two types: lock loss list and lock profit list.

Lock loss orders generally appear when there is no stop loss, the account losses are large, and it is unbearable to close the position. In order to prevent more losses or empty positions, then lock loss operation will be selected. For locked lists, unlocking is more difficult. You need to drop a list at the right place, and then the market will drop another list with the forecast, so as to unlock it successfully.

Strictly speaking, there is little difference between the profit list and the loss list. The only difference is that locking the profit sheet is operated when the account is profitable. The purpose of profit from lock orders is to open up the uncertain market through lock orders, so as to achieve long-term profit.
