When does the callback end?

Looking at reversals, we all know that trading looks at the big while doing the small; many small cycle trends finish piecing together a larger trend. The small cycle is the microscopic form of the large cycle.

So when looking at trend reversals, first observe the small cycle of 15 minutes. At least a higher high and a higher low must appear in the 15-minute timeframe to slowly change the hourly cycle. An upward movement in the hourly cycle will then evolve into a 4-hour or even daily trend, so patiently wait for the gradual evolution of each cycle and do not enter halfway up the mountain.
