The Williams %R is a momentum oscillator that helps forex traders identify overbought and oversold conditions, as well as trend reversals. In this guide, we’ll explore how Williams %R works, its advantages, and the best trading strategies to use it effectively.

Williams %R – What It Is & How to Trade with It

What is Williams %R?

The Williams %R (Williams Percent Range) is a momentum-based oscillator developed by Larry Williams to measure how close the current price is to the highest high over a specific period. It ranges from 0 to -100, identifying overbought and oversold conditions.

Williams %R is calculated using the following formula:
%R = [(Highest High – Current Close) / (Highest High – Lowest Low)] × -100

Where:

  • Current Close = Most recent closing price.
  • Lowest Low = Lowest price over the chosen period.
  • Highest High = Highest price over the chosen period.

Key Features of Williams %R

  • Identifies overbought (above -20) and oversold (below -80) conditions.
  • Generates buy and sell signals based on momentum shifts.
  • Useful for detecting trend reversals and momentum exhaustion.

Williams %R helps traders spot potential reversals:
