As long as there is a cycle, there must be a three-level trend in this movement cycle, and the fluctuation of the trend is its inevitable feature. Then wave theory and Dow theory are also applicable to the futures market, but any trend and wave shape are relative. Whether it will be applied is another question. At least at present, their applications are mostly fixed and mechanical, so the analysis of any financial market is a wrong conclusion.
In other words, there is nothing wrong with the theory, but the method of applying the theory is wrong and the connotation of the theory is not really understood. The founder just gave you a form, which needs God to understand.
It's just like Tai Ji Chuan's moves. Which secret needs to be understood, and finally forget the moves, then you can really understand.
