Williams API

Momentum oscillator bounded between -100 and 0 that locates the current close relative to the highest high and lowest low of the look-back window.

About Williams API

Williams %R reads -20 or above as overbought and -80 or below as oversold, mirroring the structure of the Stochastic but using only highs and lows. It is well suited for identifying short-term exhaustion in trending markets, especially when combined with a longer-term trend filter to avoid taking countertrend signals.
