In my opinion, RSI >45 AND RSI < 55 is unprofitable. So for the use of the masterpiece RSI + ma hist, I added two level lines of 55 and 45 to assist in the research.
(Of course, this idea may be different from the teacher's design idea)
If the teacher has free time, he might as well change the dotted line to two level lines of 55 and 45 in the original version.
Infinite merit!
