While googling, i found it under the name 'RSS - Relative Spread Strength'. Developed by Ian Copsey.
Ninja seem to have it on there platform.
Would be nice to have a version from MrTook/Kvak with the averages, mtf and arrows/vertical lines. If there isnt a version already.
It seems to find turning points nicely with some adjusted settings. the image has default settings.
