You can consider this sell-off after the rally as a warm-up exercise before the main upward wave. For the main upward wave of a bull market, the risk is high and profit-taking is significant when it rises sharply.

Around this position, sell off 2-3 times until the long positions are lightened and no one dares to go long. After heavily damaging the bulls, only then can the main upward wave of the bull market be completed in a short and quick time.
