The intraday rebound target is the 3080-3100 pressure range. Pay special attention to the changes in volume at night. If the volume continues to shrink, be alert to the second test of the 3000-point integer mark. The operation strategy is mainly to go long on the retracement. Buy on dips below 3025-3030, and pay attention to stop-profit protection above 3070. Maintain a volatile bullish pattern in the short term.
