After opening low, it rushed up and fell back, falling below the opening price, which is a strong short position during the day. However, on the one hand, it has not fallen below the neckline support of 2685, and the 100-day moving average is upward, so it is a reverse transaction, and the stop loss needs to be reduced accordingly. The trading strategy is mainly to follow the short after the breakthrough.
Trading strategy: (mean reversion) follow the short after breaking through 2700
Resistance reference: 2705
Support reference: 2700 (breakthrough); 2685; 2670
