Quote from Mushroom:
I saw a stretch - squeeze indicator in a chart by Spydertrader. Is this possible to get from somene her? Is there a version for ninjatrader?
Also read that there where videos made explaning stretch-squeeze and Ym leding, anyone know where I can find them?
For people who use this - is it hyper fine tune stuff with little practical value, or can it help you get in to good trades and avoid others?
