If this indicator and system combination fails, it will be replaced by others, which will only make you lose confidence more and more. The indicator is flawed. It is suggested to give up the study of these lagging technical indicators and study the K-line itself, and you are sure to find something predictive. As long as it is a book that introduces the skills of using K, you can also read it. What futures do is a high probability event. To have a systematic analysis method, indicators can only play an auxiliary role for you. It does not rely entirely on indicators for trading. It is necessary to have fund management, and the discipline and execution of the entry and exit strategy, as well as the accumulated experience and sense of disk and mentality control all these are not available in books.
What suits you is the best. Just study the K-line and moving average thoroughly, and all other indicators come from this. I have searched all the indicators in the world, and now there are only moving averages and K-lines left. It is suggested to look at Luo Wei's fluctuation vitality, in which the concept of "two moving averages and one indicator" is worth learning.
