On the right side, follow the trend; on the left side, invest against the trend.

It seems contradictory, but in fact, the essence is the same.

The contradiction is that one looks at the relative value of the technical aspect, and the other looks at the absolute value of the fundamental aspect.

The difficulty is that one needs to be resolute in stopping loss and taking profit, and the other needs to hold the position patiently.

The essence is the same, do not predict, observe, and wait patiently.
