Market sentiment fluctuates repeatedly, with increased long and short battles. Macroeconomic news and geopolitical situations intertwine, and short-term trends are driven mainly by emotions. If key support levels are broken, it may trigger further declines; but if capital flows back in, the rebound strength should not be underestimated. For trading, it is recommended to control position sizes, follow the trend, and avoid blindly chasing gains or selling in panic.
