Williams %R Oversold occurs when the indicator drops below -80, signaling that price is near the low of its recent range. This momentum indicator is particularly useful for timing entries in pullbacks within uptrends.

Overbought: Above -20 (note: -20, not +20)

Williams %R Calculation

%R = (Highest High - Close) / (Highest High - Lowest Low) × -100

Highest High = highest high in look-back period (typically 14)
Lowest Low = lowest low in look-back period

Understanding the Scale:

-20 to 0 = Overbought (close near top of range)
-50 = Middle of range
-80 to -100 = Oversold (close near bottom of range)

Double momentum confirmation
Reduces false signals

%R faster, Stochastic slower
%R entry, Stochastic confirmation
Both oversold = powerful setup
Similar logic, different speeds

%R + Moving Averages:

%R oversold at 50 or 200 MA = excellent
Support confluence
High probability bounce

Real-World Application

Pullback Entry in Uptrend:

Stock uptrending above 50-day MA
Pullback brings price to MA support
Williams %R drops to -96 (extreme oversold)
Bullish engulfing candle at MA
%R turns up, crosses -80
Enter long at $51.50
Stop below MA at $50
Williams %R reaches -15 (overbought)
Exit at $56.50 for 10% gain
Risk/Reward: $1.50 risk for $5 gain = 3.3:1

False Signal Avoidance:

%R drops to -75 (not oversold enough)
Or no support level nearby
Or downtrend still intact
Don’t trade - wait for better setup

Williams %R Divergence

Bullish Divergence (Very Powerful):

Price: Lower low
Williams %R: Higher low (less oversold)
Signal: Selling exhaustion
Action: Strong buy signal
Probability: 75-80% success

Best when divergence occurs at major support level with %R below -80.

Building Position:

1/3 at extreme oversold (-95)
1/3 when %R crosses -80
1/3 on bullish candle confirmation

Stop Loss Management:

Initial: Below entry low
After profit: Move to breakeven
After %R reaches -50: Trail under lows
