1. Definition of Williams %R (W%R)

Williams %R (W%R), also known as the Williams Percent Range, is a technical analysis tool developed by Larry Williams to measure the overbought or oversold conditions of an asset in relation to its recent trading range. W%R is based on the concept that as an asset approaches an overbought (or oversold) condition, it will oscillate between two extremes within its trading range.

W%R is calculated as follows:

W%R = (Highest High - Current Price) / (Highest High - Lowest Low) x -100

• Current Price: The price of the asset at the current time
• Highest High: The highest price reached during the lookback period (typically 14 or 10 periods)
• Lowest Low: The lowest price reached during the lookback period

2. Interpreting W%R Values

W%R oscillates between -100 and 0. The interpretation of W%R values is as follows:

• Overbought: When W%R exceeds -20, it indicates that the asset is considered overbought and may be at risk for a downward reversal.
• Neutral: When W%R stays within the range of -20 to -80, it indicates that the asset is not considered overbought or oversold.
• Oversold: When W%R falls below -80, it indicates that the asset is considered oversold and may be at risk for an upward reversal.

3. Trading Strategies Using W%R

• Buy Signal: Enter a long position when W%R crosses above -80, indicating an oversold condition.
• Sell Signal: Exit a long position or enter a short position when W%R crosses below -20, indicating an overbought condition.
• Reversal Confirmation: Use W%R to confirm a potential trend reversal by looking for a divergence between W%R and price. If W%R forms lower lows while price forms higher highs, it indicates a potential downward trend reversal. Conversely, if W%R forms higher highs while price forms lower lows, it indicates a potential upward trend reversal.
• Scalping Strategy: Scalp traders can use W%R to identify short-term overbought or oversold conditions for quick trades.

4. Limitations and Considerations When Using W%R

• Backtesting: It is crucial to backtest W%R trading strategies thoroughly to validate their reliability and consistency.
• Timeframe Considerations: W%R values can vary significantly depending on the timeframe and lookback period used.
• Market Conditions: W%R may perform differently in different market conditions, such as trending versus ranging markets.
