It's easier to understand with a picture👍

First, buy horizontal and buy pits, do not buy vertical; the selling point is at the boiling point.
Second, continuous small rises are real rises; continuous large rises mean to exit.
Third, a sharp drop with no volume is a scare tactic, a slow drop with volume means to withdraw quickly.
Fourth, a sharp rise requires a pullback; do not dig deep pits and do not buy heavily.
