WPR = Williams Percent Range
I modified this indicator a little bit to plot T3 and WPR as regular lines or dotted lines.
For dotted lines, you can choose any symbol such as square, triangle, diamond, etc....
If you don't want to plot WPR, then change the color to NONE.
WPR (2) is great to spot Peaks and Valleys.
