Isn't this also a kind of bull market? Truly understanding trading actually only requires mastering one thing: trading the trend. Entering at any given point doesn't really matter; randomly entering during a red line is also correct. It looks simple, but the difficulty lies in "I'm not sure if this is a trend." This judgment is implicit, called "market condition," which requires approximation through calculation. As long as the condition is right, the trading trend direction, timing the volatility, is simple but abstract.
