The structure of the pie 30F:

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ There is a possibility of a 30F bottom divergence here. If it rebounds here, it is expected to go to around 16200.

Then walk a 30F decline or form a central 30F center. Looking at the strength of the second 30F decline, if the intensity cannot fall below the previous low, it will easily form a 2h rising.
