Williams %R, developed by Larry Williams, is a momentum oscillator that measures overbought and oversold levels in a market. Unlike other oscillators, Williams %R compares the closing price of a security to its high-low range over a specific period, typically 14 days. By understanding how to use Williams %R, traders can identify potential reversal points, spot trends, and optimize their trading strategies.

What is Williams %R?

Williams %R is a momentum indicator that oscillates between 0 and -100. The indicator’s readings reflect how the current closing price compares to the highest high and lowest low over the specified period. Williams %R is similar to the Stochastic Oscillator but is plotted on an inverted scale, making it easier to identify overbought and oversold conditions.

Understanding Williams %R in Plain Language

Here’s how Williams %R works:

1. Calculation of Williams %R:
   • Williams %R compares the current closing price to the high-low range over a specific period (usually 14 days) to determine the relative position of the price within that range.
   • Formula: %R = (Highest High – Close) / (Highest High – Lowest Low) * -100
   • If the current close is near the highest high, Williams %R will be closer to 0, indicating an overbought condition. If the current close is near the lowest low, Williams %R will be closer to -100, indicating an oversold condition.

Using Williams %R in Trading

Williams %R can be applied in several ways to enhance your trading strategy:

1. Identifying Overbought and Oversold Conditions
   • Overbought Condition: When Williams %R rises above -20, it indicates that the security may be overbought, meaning the price has risen too quickly and could be due for a pullback or reversal.
   • Oversold Condition: When Williams %R falls below -80, it indicates that the security may be oversold, meaning the price has dropped too quickly and could be due for a bounce or reversal.
2. Spotting Reversals
   • Bullish Reversal: A bullish signal occurs when Williams %R crosses above -80 after being in oversold territory. This suggests that the downward momentum is weakening, and a reversal to the upside could be near.
   • Bearish Reversal: A bearish signal occurs when Williams %R crosses below -20 after being in overbought territory. This suggests that the upward momentum is weakening, and a reversal to the downside could be near.
3. Confirming Trends
   • Trend Confirmation: Williams %R can be used to confirm the strength of a trend. For example, if the price is rising and Williams %R consistently stays above -50, it suggests that the uptrend is strong. Conversely, if the price is falling and Williams %R consistently stays below -50, it suggests that the downtrend is strong.
   • Divergences: Williams %R can also highlight divergences between price and momentum. A bullish divergence occurs when the price makes a lower low, but Williams %R makes a higher low, indicating weakening bearish momentum. A bearish divergence occurs when the price makes a higher high, but Williams %R makes a lower high, indicating weakening bullish momentum.
4. Combining Williams %R with Other Indicators
   • Moving Averages: Combining Williams %R with moving averages can help confirm trend direction and strength. For example, if Williams %R signals an oversold condition and the price is above a key moving average, it could be a strong signal to consider entering a long position.
   • Relative Strength Index (RSI): Using Williams %R alongside the RSI can provide additional confirmation of overbought or oversold conditions. If both indicators suggest an oversold condition, it could be a strong signal to consider buying.
