Thanks; I think I have the lines now.
The screenshot (1) shows where I think (only an example) the histo colouring of the WPR subwindow should be
(fast and slow slope up - blue; fast and slow slope down - salmon)
Screenshot (2):
I reproduced the WPR with your StochFiltered
so:
whenever slow+fast Stoch = Blue = WPR histo blue (up)
whenever slow+fast Stoch = Red = WPR histo red (down)
(except: for up: if < 20 no up signal in histo; for down: if >80 no down signal in histo)
