Williams %R

Also called: williams percent r, %r

A momentum oscillator similar to stochastics that measures overbought and oversold conditions on an inverted scale (-100 to 0).

Williams %R is a momentum indicator created by Larry Williams. It scales between -100 and 0. Readings above -20 are overbought. Readings below -80 are oversold. The math is essentially an inverted version of the stochastic oscillator — the two indicators give very similar signals. The main strength of Williams %R is its responsiveness. It reacts faster to price changes than RSI or stochastics, which makes it useful for short-term trading. The downside is that it whipsaws more in choppy markets. Like all overbought/oversold oscillators, %R works best in ranging markets and fails in strong trends. Always confirm signals with price action and structure before trading them.
