The popular points of resistance level and support level refer to those key positions analyzed above the disk surface. Above the price is called resistance level, below the price is called support level.
When the price is close to the resistance level, you can short. After breaking through the resistance level, the previous resistance level becomes a support level, and you can buy up backhand. When the price is close to the support level, you can buy up and fall below the stop-loss support level. After the price falls below the support level, the previous support level becomes a resistance level, and you can make a backhand short. The resistance level and support level are mainly determined by some indicators and drawing lines, which requires high technical skills.
Judgment method:
For example, every time I see the K-line touch a point, it will rebound or callback. Then this point is pressure or support.
. The resistance level is a position where you can't go up or down, and the support level is a position where you can't go down or down. If you look at the K-line chart, the peak refers to the resistance level, and the peak and valley are the support level.
