based on Constance Brown's observation, that bull range is 40 to 80 and bear's 20 to 65 (almost strictly).
The histogramm tells you which longer term market you#re in.
The short term curves identify the wave within the trend (similat to EW impulse / corrective) incl. overdoing action
Example: longterm= green, wave =red--> Bullmarket, corrective wave etc.
(I locked this one to remind you that the length of the indicators are essential)
