The height of the rebound is also limited, it's difficult to break through the 60 moving average at the 3491 position in 1 hour, this week looks like a bottom exploration and rebound. Today's 15-minute double bottom divergence is the best opportunity and a short-term buying point. If it returns to around 3306 again, it can be a good entry point for short-term trading. Many funds will definitely wait for the double bottom divergence before entering to catch the bottom.
