2. Click the golden section line in the online drawing toolbar. If an upward trend is going to fall after the end, draw it from a relative high point to a previous relative low point on the trend chart; On the contrary, draw from the low point to the previous high point, so that the main support level and resistance level can be drawn.

Precautions for application:

The golden section principle is derived from Fibonacci sequence. The well-known golden ratio of 0.6 18 is the ratio of two adjacent values in Fibonacci series, and based on this, more important ratios such as 0. 19 1, 0.382 and 0.809 are calculated. Among them, the most commonly used ratios in the golden section are 0.382 and 0.6 18. When this ratio is applied to the analysis of foreign exchange market, it can be understood that the positions corresponding to the above ratio are generally prone to strong support and pressure.

When applying the golden section and percentage line, it should be noted that the two most important lines of the golden section are 0.382 and 0.6 18. In the rebound market, the 0.382 position is the weak rebound target position, and the 0.6 18 position is the strong rebound target position. In the callback process, if there is a strong callback, the 0.382 line should have strong support. If it is a weak callback, the 0.6 18 line is a strong support level.
