Yesterday, many people chased the short position, and after the market temporarily dipped below support, it quickly recovered. A rally then caused many to get liquidated, so in trading, you must wait for that key turning point. Don't chase the highs or sell at the lows. The missed opportunity can be waited for next time. Once the principal is gone, it's really gone.

After forming a double bottom intraday, the market will continue to rise, but the flag pattern has already broken down. After a rebound to the lower edge of the flag, the price still continues downward. This rebound will once again present a better shorting opportunity.
