Here is a lovely indicator that was posted by Mntiwana back in the TSD days which I really liked. I couldn't find this particular version on our site so I'd like to post it here

The IFT (Inverse Fisher Transform) WPR (Williams %R) which also comes with Multi-timeframe + Interpolation.

PS: If you're looking for the Super Smoother Adaptive version, this one was posted here IFT Of Adaptive Super Smooth WPR by Mrtools.
