The arrows have meaning after crossing the boundaries of the asymmetric channel and the simple channel of the bollinger, at the moment when the asymmetric is rebuilt from low and becomes high.
Just need to take into account the direction that the arrows become good signals. And just pick up periods.
In the picture, the MA periods are both 8 by the hourly chart.
This is the dimension of one trading session.
