The short answer

The Williams %R (%R) is a momentum indicator rated intermediate. Applied to USD/CAD (major pair, 1.2-pip spread, 70-pip daily range), the default settings are Period: 14. Overbought: −20. Oversold: −80. Best timeframes: M15, H1, H4. Key signals: Buy when %R crosses above −80 (leaving oversold). Sell when %R crosses below −20 (leaving overbought). Best used as a timing tool within a confirmed trend, not as a standalone signal.

What Is the Williams %R?

Similar to the Stochastic oscillator but inverted — ranges from 0 to −100. Overbought above −20, oversold below −80. Fast and reactive. %R = (Highest High − Close) / (Highest High − Lowest Low) × −100. It measures where the current close sits within the recent high-low range. More sensitive than RSI — good for timing entries in confirmed trends.

%R Signals on USD/CAD

Buy when %R crosses above −80 (leaving oversold). Sell when %R crosses below −20 (leaving overbought). Best used as a timing tool within a confirmed trend, not as a standalone signal. On USD/CAD, trade these signals during the New York session (8 AM – 5 PM ET) for the cleanest price action and tightest spreads. Outside peak hours, %R signals are noisier because volume thins and spreads widen.

How to Trade USD/CAD with %R

  1. 1

    Add %R to your chart

    Open USD/CAD on your preferred timeframe (M15 or H1 or H4 recommended). Apply the Williams %R with default settings: Period: 14. Overbought: −20. Oversold: −80.

  2. 2

    Confirm the trend on a higher timeframe

    Before acting on any %R signal, check one timeframe up for the prevailing trend. Trade %R signals in the direction of the higher-timeframe trend for higher win rates.

  3. 3

    Wait for a clear %R signal

    Don't anticipate — wait for the signal to complete. Buy when %R crosses above −80 (leaving oversold).

  4. 4

    Set stop and target before entering

    Use the position size calculator. Risk 1% per trade. On USD/CAD with a 70-pip daily range, typical stops are 14–28 pips.

  5. 5

    Manage and journal

    Move stop to breakeven after 1R. Let the trade run toward 2–3R. Journal the %R signal quality so you build data on which signals work best for USD/CAD.

When %R Fails on USD/CAD

No indicator works in every condition. %R is a momentum indicator, which means it performs best in range-to-trend transitions and struggles when momentum is flat. On USD/CAD, avoid using %R during the Asian session (for this pair) and during the first 5 minutes of major news releases when price spikes are noise, not signals.
