High and low points did happen, not the top and bottom of the wave. The main reasons are: 1 and Wave 5 failed; 2. 5 irregular wave B-ultrasound; 3. The C wave of the contraction platform shall not exceed the A wave; 4, triangle adjustment and so on.
For these irregular shapes, the reason why there are no high and low points at the top and bottom is mainly analyzed by experience accumulation. For different analysis schemes of a wave, the end position of the wave will be different, so the top and bottom positions should also be analyzed in combination with the schemes. According to the previous analysis scheme, the top and bottom of many waves are not fixed.
In fact, every detail of wave theory analysis in actual combat is related, not independent. When you ask a question, all the parameters to solve it are also questions. Without solving them as a system, it is impossible to perfect the application of wave theory.
