How to deal with high opening and low going: First, after the opening, the price jumped on the 5-day moving average. If there is no gap for 30 minutes, you can enter the arena. But always pay attention to the price and avoid a sharp correction. If there is a gap in 30 minutes, you will be short.

Second, the price gap fell below the 5-day moving average after the opening. If there is no gap for 30 minutes, you can enter the arena. If there is a gap in 30 minutes, you will be short.

Third, the moving average is not empty, and the 30-minute line is empty. Wait and see.

Generally speaking, it is to grasp the time period of the breakthrough point. As long as the K-line doesn't jump, you can enter the arena. Once you jump, just wait and see.
