Inventor: Larry Williams
Larry Williams’ answer to the false divergences of single-period oscillators. It measures buying pressure across three timeframes at once – 7, 14 and 28 bars – and blends them with more weight on the shortest. Moves between 0 and 100. Its famous strength is the quality of its divergence signals.
Default period: 7, 14, 28
Above 50 indicates buying pressure winning overall. Below 50 indicates selling pressure winning.
Useful readings:
Above 70: Overbought zone
Below 30: Oversold zone
Crossing above 50: Pressure balance turned bullish
Price makes new low but oscillator holds higher: Bullish divergence across three timeframes, high quality
Price makes new high but oscillator lower: Bearish divergence, rally hollow
Williams’ own rule: the divergence plus a breakout of the oscillator’s high is the real buy signal
Objective rules:
Bullish: Bullish divergence forms (price lower low, oscillator higher low with the low under 30) AND the oscillator then breaks above its high made during the divergence.
Bearish: Bearish divergence forms (price higher high, oscillator lower high with the high above 70) AND the oscillator then breaks below its low made during the divergence.
Simple version bullish: Oscillator crosses above 50
Simple version bearish: Oscillator crosses below 50
Long exit: Oscillator crosses above 70 and turns down
What makes it unique:
It blends three timeframes into one buying-pressure reading to kill the false divergences of single-period oscillators. Williams’ three-step divergence signal remains its unmatched signature.
