First of all, look at the panorama, that is, in time, it will definitely not be a short period of time or a month or two, but a year, two years or even longer. Such a K-line diagram can be called a panorama. Only by looking at the whole picture can we understand the process of market rotation (or village change), that is, the process of mainstream funds from the first inflow and outflow to the next new inflow and outflow. Therefore, when you look at the computer in the sales department, you can immediately judge whether the other party's method of looking at the K-line diagram is correct by the length of time that the other party looks at the K-line diagram.
