First of all, we must find the highest and lowest of the previous band. When the golden section is drawn from high to low, there will be three important positions: 0.6 18, 0.5 and 0.382. These positions are often the approximate positions of market turning or market adjustment. However, the golden section can be said to be very ineffective. If it is combined with other theoretical methods, it is very useful, such as waves and Gann. If you are interested, study it yourself.
