Have you noticed that there is a very useful pattern in this market segment, what was it called... W...

The pattern mentioned in this article is not a single K-line form, but an obvious shape composed of multiple K-lines. There are many common forms that we usually see, including the "M"-shaped top and "W"-shaped bottom that I often talk about.
1. W bottom
The W bottom can also be called the bottom 2B form. In fact, when broken down, it is a decline - an automatic rebound - a second test. It can occur at any level, ranging from less than 1 minute to more than a week. All these structures are potential reversal patterns. The picture below is an example of a perfect W bottom (bottom 2B).
