What Williams %R measures
Williams %R, created by Larry Williams, shows where the latest close sits within the high-to-low range of the last few periods, on a scale from 0 down to -100. A reading near 0 means the close is near the top of the recent range; near -100 means it is near the bottom. It is the stochastic oscillator turned upside down.
Overbought and oversold
Many traders read values above -20 as overbought and below -80 as oversold. In a strong uptrend %R can stay above -20 for a long time, so traders often wait for it to turn back through the level, or check the trend first, before acting.
