A momentum oscillator (range 0 to -100) that shows the current close relative to the highest high over a lookback period. It is essentially the inverse of the Fast Stochastic. Values near 0 indicate overbought; near -100 indicate oversold. EAs use %R similarly to RSI/Stochastic (e.g. overbought/oversold signals). In MetaTrader, use iWPR() to compute Williams %R.
