Generally speaking, there are three reasons for taking profits:

1. Already have profits in hand

2. Anticipate market reversal

3. Judgment becomes unclear

Stop loss also occurs for three reasons:

1. Changes in market judgment and expectations

2. Potential loss potential is too high

3. Judgment becomes unclear

In fact, no matter whether you take profit or stop loss, the most difficult and important thing is to treat the third situation rationally.
