Williams %R, developed by trader Larry Williams, shows where the latest close sits within the range of recent highs and lows. It runs from 0 at the top of the range to −100 at the bottom.
How it is worked out
Over the last 14 periods (the usual setting), find the highest high and lowest low. Williams %R = (highest high − latest close) ÷ (highest high − lowest low) × −100. A close at the high gives 0; a close at the low gives −100.
Reading it
Readings from 0 to −20 are commonly called overbought and from −80 to −100 oversold. It moves the same way as the fast stochastic oscillator's %K, just on an upside-down scale: Williams %R equals %K minus 100.
