Strictly speaking, lock in profit is not much different from lock in loss, the only difference is that when locking in an account, one account holds a loss and the other holds a profit. The suggestion is to lock in profits and take profits in a timely manner or follow up on mobile stop losses, because placing an additional order is not as good as placing an order after the market is clear.
Because locking in profits locks in profits, it is relatively easier to solve and causes much less psychological burden. Although it is said that, the principle of releasing an order is actually similar to that of releasing a loss order. Because the two want to achieve similar results, one is to reduce losses, and the other is to strive for maximum returns. There is a saying in investment: reducing losses is equivalent to gaining benefits.
