In most cases, price fluctuations are repetitive and unstable. Therefore, the profit and loss curve of the transaction is also repeated and shaky.

In the case of profit, the profit rate will also retreat. If the retreat is free to change, it may lead to a profit loss or even a big loss.

Therefore, take profit is a way to control profit taking, and it is a disguised stop loss.

In short, stop loss is necessary, but it can't guarantee profit. At the same time, the determination and use of stop loss conditions must be cautious and must match the entry conditions.

In addition, take profit is a disguised stop loss and is also necessary. In this way, investors have a chance to get the final profit.
