1. This graph is generally composed of two positive lines, and there is obvious stagflation on the disk surface, which is a double-top graph. Generally speaking, the two highest points of the double head are not necessarily on the same horizontal line, and the difference between them is less than 2%.
2. It is worth noting that the second head may be a little higher than the first head, because the bulls try to push the stock price to continue rising again, but they can't make the stock price rise more than 2%.
3. The second low point of the double bottom is slightly higher than the first low point, because prophetic investors have already started buying when they fall back for the second time, so it is impossible for the stock price to fall back to the previous low point. So this round-trip, double-top pattern was formed.
The above is what I found for you about the double roof, I hope it will help you.
