It should be 0.382/0.5/0.6 18 area. Another key premise supported by the golden section is that the general trend is certain. Therefore, the golden section line is usually used in conjunction with the moving average system, and it does not make much sense to use it alone.

The golden ratio refers to dividing the whole into two parts, and the ratio of the larger part to the whole is equal to the ratio of the smaller part to the larger part, and the ratio is about 0.6 18. This ratio is recognized as the most aesthetic ratio, so it is called the golden section. It is said that in ancient Greece, Pythagoras was walking in the street one day. Before he passed the blacksmith's shop, he heard the blacksmith strike the iron, so he stopped to listen. He found that the blacksmith had a regular rhythm in striking iron, and the proportion of this sound was expressed mathematically by Pythagoras. The golden ratio not only plays an important role in painting, sculpture, music, architecture and other artistic fields, but also plays an important role in management and engineering design.
