(It is not easy to write, thank you for liking and sharing. Uncle Ai will share a method of finding support and pressure points by combining real pictures today)
1. How to draw the support and pressure levels of the horizontal line
Connecting two or more relative low points into a straight line will give you the support line; connecting two or more relative high points into a straight line will give you the pressure line.

2. How to draw support and pressure levels of trend lines
In an upward trend, connect two low points with a straight line to get an upward trend line. In a downward trend, connect two high points with a straight line to get a downward trend line.
Take gold as an example as shown below

Three Fibonacci lines draw support and pressure levels (commonly known as the golden section)
Drag from a relatively low point to a relatively high point to get the golden section line. (Usually the larger the level, the stronger the support pressure)

Four channel lines draw support and pressure levels
Orbital lines, also known as channel lines or pipeline lines, are a method based on trend lines. After the trend line has been obtained, a parallel line to the trend line can be drawn through the first peak and trough. This parallel line is the orbit line.

Five How to draw retracement, support and resistance levels
Drag the mouse from a relatively low point to a relatively high point to get a percentage line.
(This wave retracement is used more frequently, and the ratio of 50 38 62 is also the golden ratio. If you don’t understand it clearly, you can use Rafi wave to measure it.)
