I will update some technical analysis teaching in the near future. Are any friends interested?

The teaching is all my notes from my previous study. Because the online courses may be taught by A-share lecturers, some of them are tactics and the names may be a bit "martial arts style". This is mainly the aspect that may need to be adapted.

I update the content of industry research in the square, and the most frequent is the secondary tendency. In fact, I don’t know how many friends like to read my project analysis in the square😂
