Willams% Fisher transformed confermated by BB%

Using the Willams% sharped by Fisher tranformer , it s easy to find the bottom and top, and the BB% conferm the minimum. I plot as colored columns : yellow when the price touch the BB , and red or green when price move out from the bands, if the line of Willams also reach the top or bottom, that's the moment to act. In all indicator can change the setting as you like
