What is ta.wpr() in Pine Script?

ta.wpr(length) returns Williams %R using the chart high/low/close over the lookback window, scaled from -100 (weak) toward 0 (strong within the range).

What are the overbought/oversold levels for Williams %R?

Common conventions use roughly -20 for overbought and -80 for oversold, inverted versus many 0–100 oscillators because %R ranges -100 to 0.

How does Williams %R differ from Stochastic?

They are related range-based momentum concepts; %R is typically inverted and scaled -100..0, while raw stochastic %K is often 0..100. Both compare close location within the period range.
