According to my experience, diverging is the most useful indicator to call near term top or bottom. Of course, not everytime it will work. But most time, you got to be very careful when negative diverging emerges. And probably aggressive when positive diverging emerges. It is just one of those things weather you believe TA or not. 此时就是宁可信其有不可信其无。前几天辩论TSM时咱就指出这个担心（基本面那是一点都不差，但是money flow总是领先一步）。
I also don't believe such diverging can be resolved in a few days. Usually it lasts for weeks or months because of sentiment change.
