Let me tell you, that's a technical indicator with future functions. At rest, his hint is perfect. Unfortunately, in practice, with the constant change of data, that indicator will become more and more unstable. Of course, at the big level, such as the daily chart, I can't see anything for the time being. But at a smaller level, such as 5 minutes, 30 minutes. That indicator will become more and more unreliable. You have to trust this Cai Duyu. Taking out that indicator is to fool people into going to him for training. Ha ha. Give you a technical index similar to his index, and also look at the 0 axis. I'll upload it for you. On the static diagram, it is perfect.
