it is possible in theory, but it is basically impossible in reality. Why? For example, to generate a hub in 3 minutes, it takes five minutes for three consecutive trends. These three trends can be a consolidation of 3+3+3 to form nine segments, or the expansion of two hubs with overlapping parts, or the connection of three trends. Then a 5-minute hub can be divided into three 1-minute trend types, so we don't know which one the market will take. Therefore, it is unnecessary and impossible to push down the upper level. It is different to deduce from low level to high level. For example, if only a 3-minute hub is formed now, then the seasonal level adjustment in the second paragraph will definitely not occur. Only after stepping out of the monthly hub will it be possible to adjust the seasonal level. However, if only the daily hub appears, and then it goes out of the daily trend, then we know that the adjustment of the seasonal level will not appear, because there is no high-level hub.
