Hedging can lock the current status to a certain extent, which is conducive to protecting the position.

Needless to say, there is a stop loss, which has a good role in protecting the position for the potential big losses caused by unexpected events.

The same is true for reducing the size of positions. There is nothing accurate about the price of foreign exchange transactions. Although reducing the position size will also reduce the profit, it will also reduce the loss under the same price movement range, which is also a good way to protect the position.
