🌍Mastering the Williams %R Indicator: A Powerful Tool for Spotting Reversals

 💡 What is the Williams %R Indicator?

The Williams %R is a momentum-based oscillator developed by Larry Williams. It is designed to identify overbought and oversold conditions in the market.

  • Formula:

    %R=HighCloseHighLow×100\%R = \frac{High - Close}{High - Low} \times -100
  • Range: 0 to -100

    • Near 0: Overbought

    • Near -100: Oversold


🎯 Why Use the Williams %R?

  1. Highly responsive: More sensitive than RSI

  2. Effective in spotting reversals: Ideal for swing and short-term traders

  3. Great with other indicators: Pairs well with MACD, Bollinger Bands, and ADX


📘 Key Trading Strategies

✅ 1. Identify Overbought/Oversold

  • %R > -20 → Overbought

  • %R < -80 → Oversold
    Combine with trendlines or patterns for confirmation.

✅ 2. Trend-Following Setup (with MACD)

  • MACD shows bullish crossover

  • %R drops to oversold → Buy opportunity

  • MACD bearish + %R > -20 → Short signal

✅ 3. False Breakout Filter

  • If price breaks Bollinger Band upper range but %R remains overbought, beware of a false breakout.
