The rebound is under pressure and the retracement is further

From the 4-hour analysis, the support below today is around 3309-16.

The short-term bullish strong dividing line is around 3295-3301. The overall bullish rhythm of high-altitude and low-multiple continues to remain unchanged.

Before the daily level falls below the 3300 mark, any retracement is a long opportunity, and short positions against the trend should be cautious.
