Williams %R Trading: Fast Momentum Oscillator
Williams %R is a fast momentum oscillator with an inverted scale. Learn to read overbought/oversold zones and failure swings for quick reversal trades.
- %R scale is inverted: 0 to -20 = overbought, -80 to -100 = oversold. Similar to Stochastic, faster.
- Failure swings (momentum divergence) are reliable reversal signals. %R can't reach extreme = momentum failing.
- Thrive displays Williams %R with overbought/oversold and failure swing alerts.

Click through Williams %R signal types:
%R below -80 = oversold. Price near bottom of recent range. Note: scale is 0 to -100 (inverted). -80 to -100 is oversold zone.
%R Level
%R below -80
%R < -80 = oversold, look for bounce. Best at support levels. Wait for %R to turn up above -80 for confirmation. Works in ranges; careful in downtrends.
What Is Williams %R?
Williams %R shows where close is in the high-low range. Developed by Larry Williams. The scale is 0 to -100 (inverted from most oscillators). 0 = close at range high. -100 = close at range low.
It's essentially Stochastic %K with an inverted scale. No smoothing makes it faster and more sensitive.

Williams %R Signals
Overbought (0 to -20)
Price near range high. Potential for pullback. Wait for %R to turn down below -20 for signal. Best at resistance.
Oversold (-80 to -100)
Price near range low. Potential for bounce. Wait for %R to turn up above -80 for signal. Best at support.
Failure Swing
%R fails to reach previous extreme. Shows momentum divergence. Price new low + %R higher low = bullish failure swing. Reversal signal.
| %R Level | Zone | Price Position | Meaning |
|---|---|---|---|
| 0 to -20 | Overbought | Near high | Pullback likely |
| -80 to -100 | Oversold | Near low | Bounce likely |
| Above -50 | Bullish | Upper half | Favor longs |
| Below -50 | Bearish | Lower half | Favor shorts |
Failure Swings
Failure swings are the strongest %R signal. When %R can't reach its previous extreme while price does, momentum is failing.
- Bullish failure: Price new low, %R higher low (can't reach -100 again)
- Bearish failure: Price new high, %R lower high (can't reach 0 again)
More reliable than simple overbought/oversold. Shows actual momentum divergence.

Common Mistakes
- Trading every extreme: In trends, %R stays extreme. Don't fade trends.
- Ignoring trend: Filter %R signals by trend direction for reliability.
- No confirmation: %R alone isn't enough. Combine with price action.
- Confusing scale: Remember: 0 = overbought, -100 = oversold (inverted).
Frequently Asked Questions
What is Williams %R?
Momentum oscillator showing where close is relative to high-low range. Scale 0 to -100 (inverted). Created by Larry Williams. Similar to Stochastic but inverted scale.
Why is Williams %R scale negative?
Convention from original formula. 0 = price at range high (overbought). -100 = price at range low (oversold). 0 to -20 overbought. -80 to -100 oversold.
Williams %R vs Stochastic?
Nearly identical calculation, different scale. Stochastic: 0-100. Williams %R: 0 to -100 (inverted). %R often faster, no smoothing. Stochastic has %K/%D.
What are %R overbought/oversold levels?
0 to -20 = overbought (price near range high). -80 to -100 = oversold (price near range low). Trade reversals at these extremes with confirmation.
What is a Williams %R failure swing?
%R fails to reach previous extreme. Bullish: new price low, %R higher low (can't reach -100 again). Shows momentum divergence. Reversal signal.
How do I trade %R signals?
Oversold + turn up = buy signal (at support). Overbought + turn down = sell signal (at resistance). Confirm with price action. Don't trade in vacuum.
What %R settings work best?
14 periods is standard. Shorter (10) more sensitive. Longer (21) smoother. Test for your timeframe. Match to Stochastic if comparing.
Does Williams %R work for crypto?
Yes. Fast oscillator useful for crypto volatility. Works well on 15M-4H charts. Combine with trend filter for best results.
