After this period of loss, I have some new insights

Three points in total

First, the general direction must be accurate.

This is the most important, hard indicator, which directly determines whether it is a profit or a loss.

Second, recognize and be willing to execute the appropriate stop loss.

This determines that when you look at the wrong direction, you will lose less or even earn less.

Third, the determination to never give up.

This determines whether you can keep up with the market when it comes.
