Williams %R (Williams Percent Range) was developed by Larry Williams. It is a momentum oscillator that moves between 0 and โ100, showing where the current closing price sits relative to the highest high over a lookback period. It is essentially the inverse of the Stochastic %K.
Reading Williams %R
| %R Level | Signal | Interpretation |
|---|---|---|
| 0 to โ20 | Overbought | Price is near the top of its range |
| โ20 to โ50 | Neutral bullish | Moderate bullish territory |
| โ50 | Midpoint | Neither overbought nor oversold |
| โ50 to โ80 | Neutral bearish | Moderate bearish territory |
| โ80 to โ100 | Oversold | Price is near the bottom of its range |
Note: Williams %R is inverted โ the overbought zone is near 0 (not 100 like RSI). Keep this in mind when reading charts.
