1, and the golden ratio is 0.6 18. The golden ratio, also known as Huang Jinlv, means that there is a certain mathematical proportional relationship between the parts of things, that is, the whole is divided into two parts, and the ratio of the larger part to the smaller part is equal to the ratio of the whole to the larger part, and its ratio is about 1:0.6 18, that is, the long segment is 0.6 18 of the whole segment.

2. The golden section is one of the most common and popular tangent analysis tools in the stock market. In practice, the golden section is mainly used to reveal the adjustment support level in the rising market or the rebound pressure level in the falling market.

3. However, the golden section does not take into account the impact of time changes on the stock price. The revealed support and pressure levels are relatively fixed, and investors don't know when they will reach them.

4. Therefore, if the index or stock price is sideways at the top or bottom for too long, its reference function will be discounted. Compared with Gann angle line and Gann arc line, it is slightly inferior, but this does not affect the position of golden section as a practical tangent tool.

Generally speaking, it is better to design a news frame close to this ratio in the layout. Commonly used frame ratios are 3: 5, 5: 8, 8: 13, etc. Of course, it is not only a rectangle with this ratio that has aesthetic feeling. Coupled with the influence of various factors in layout design, it should be impossible to arrange every news item into a rectangle with this ratio.
