What is Williams %R indicator?

The Williams %R indicator was created by Larry Williams who has created several technical indicators and is a famous trader.

Williams %R is a momentum-based oscillator to identify overbought and oversold conditions.

%R Oscillates between 0 and -100. When the value is closer to zero, it indicates overbought conditions and when closer to -100 indicates oversold conditions.

Trading Signals

Williams himself set the parameters of overbought as any reading between 0 and -20. His oversold parameters were readings between -80 and -100. It is important to note that these values are traditional examples. It may be beneficial for the technical analyst to set different parameters based on the specific instrument being analyzed. Wider or narrower overbought and oversold levels may be appropriate based on historical analysis.


The following is an example signal strategy

  1. Buy when the %R drops below the Minimum threshold (-80 by default)
  2. Sell when the %R exceeds above the Maximum threshold (-20 by default)

How to calculate Williams %R?

%R = (Highest High – Current Close) / (Highest High – Lowest Low) x -100

  • Highest High = Highest High for the look-back period.
  • Lowest Low = Lowest Low for the look-back period.

Most commonly used period is 14.
