Take a rising line as an example, select three reference points (rising point, stage vertex and callback point). From the callback point, the system will derive 38.2%, 6 1.8%, 100%, 138.2%, 16 1.8% of the first absolute increase. When the third wave crosses the high point of the first wave, the success probability of using the wave ruler is greater, and the first wave can generally be completed, with an absolute increase of 2 times.

Oriental Jinyu stock rose to 15.23 yuan after 12.72 bottomed out, so the absolute increase of the first wave was15.23-12.72 = 2.51,and then it was adjusted back to 13.39. So the subsequent pressure level is13.39+2.51*1=15.9,13.39+2.51*1.382 = ...

In the end, the stock peaked at 18.27 (twice the absolute increase of the first wave). Therefore, when the third wave is established (crossing the high point of the first wave), we can judge the price at which the stock price peaked, so as to make a strategy of selling in batches and obtain better value.
