Another coding mashup experiment
It's as simple as London Underground, when price exits the 'RED' main line board the train & get off at the next platform :)

How can I make a strategy from your indicator? Not good at writing scripts.
This is quite interesting, but my hunch is that the center line is repainting after the fact. Am I off? Can you take a sec and explain what the red center line is? Thanks!
