The K-line combination form that goes through the head and the foot:
Like comment➕like👍
It is a typical mid-term trend signal. It is composed of two K lines. The second K line penetrates the first K line from head to toe. There are two forms of piercing the head and feet, one appears at the bottom; the other appears at the top. Whether it is the bottom or the top, it is a signal of trend change, that is, the original downward trend turns into an upward trend, or the original upward trend turns into a downward trend.
The specific points are as follows:
1. There must be an obvious upward or downward trend in advance.
2. The two K lines in the downward trend are the Yin line first and then the Yang line; the two K lines in the uptrend are the Yang line first and then the Yin line.
3. The physical part of the second K-line must be enough to eat up the entire first K-line (the upper and lower shadow lines are not counted).
4. The greater the difference in the length ratio between the first and second K lines, the stronger the trend will generally be.
5. The second K-line contains more previous K-lines (for example, two or more), generally the stronger the trend will be.
6. This kind of over-the-top K-line combination appears on the 1-hour K-line chart, representing a short-term trend at the hourly level. Appears on the daily K-line chart, representing the midline trend of the daily level. Appearing on the weekly K-line chart, it represents a long-term trend change at the weekly level.
