How to Interpret Williams %R Are Calculated?

10 minutes read

Williams %R is a technical indicator used in technical analysis to determine whether a market is overbought or oversold. Developed by Larry Williams, it is calculated by comparing the current closing price to the highest high and lowest low over a given time period.


To calculate Williams %R, follow these steps:

  1. Determine the time period: Decide on the number of periods you want to use to calculate Williams %R. The most commonly used period is 14 days, but it can be adjusted based on your trading style and preferences.
  2. Identify the highest high and lowest low: Look at the price data for the chosen time period and determine the highest high and lowest low. The highest high represents the highest price reached during the time period, while the lowest low represents the lowest price reached.
  3. Calculate the raw value: Subtract the current closing price from the highest high and divide it by the difference between the highest high and lowest low. Multiply the result by -100 to obtain the raw value. The formula for the raw value is: ((H - C) / (H - L)) * -100; where H is the highest high, L is the lowest low, and C is the current closing price.
  4. Interpret the result: Once you calculate the raw value, you will get a result between -100 and 0. A value close to -100 indicates that the market is oversold, suggesting a potential buying opportunity. On the other hand, a value close to 0 suggests the market is overbought, indicating a potential selling opportunity.


Williams %R is often represented as a line graph that oscillates between -100 and 0, with -80 to -100 considered oversold and 0 to -20 considered overbought. Traders use Williams %R in conjunction with other technical indicators and price patterns to make trading decisions.


It is important to note that Williams %R is a momentum oscillator and can generate false signals, especially in trending markets. Therefore, it is advisable to combine it with other indicators and analysis techniques for more accurate predictions.

How to interpret a Williams %R reading above -20?

A Williams %R reading above -20 is considered as an overbought condition. The Williams %R is a technical indicator used to measure the momentum in a stock or other financial asset. It is plotted on a scale from -100 to 0, with levels above -20 generally indicating an overbought condition and levels below -80 indicating an oversold condition.


When the Williams %R reading is above -20, it suggests that the recent price movement has pushed the stock or asset into a highly overbought state. This means that the price has risen sharply and quickly, potentially creating a situation where the asset is trading at a relatively high price compared to its intrinsic value.


Interpreting a Williams %R reading above -20 can have different implications depending on the overall market conditions. Some traders might consider this as a sell signal or an indication that the stock is due for a pullback or correction. It could suggest that the price has become unsustainable and that a reversal or downturn in price is likely in the near term.


However, it is important not to rely solely on a single technical indicator for making trading or investment decisions. It is recommended to consider other indicators, chart patterns, and fundamental analysis to gain a comprehensive understanding of the market situation before taking any action.


How to interpret Williams %R calculation in technical analysis?

Williams %R is a popular technical analysis indicator that measures the extent of the recent price movement in relation to the highest high and lowest low over a specified period of time. It is useful for identifying overbought or oversold conditions in a market.


Interpreting Williams %R involves understanding its scale and the key levels it generates:

  1. Scale: Williams %R fluctuates on a scale of -100 to 0. Values close to -100 indicate that the price is near or at the lowest low of the selected period. Conversely, values close to 0 indicate that the price is near or at the highest high of the selected period.
  2. Overbought and Oversold Levels: While the scale ranges from -100 to 0, traders often focus on two key levels: -20 and -80. When Williams %R crosses below -20, it suggests that the price is overbought, and a potential reversal or correction may occur. Traders might consider selling or entering short positions at this point. When Williams %R crosses above -80, it suggests that the price is oversold, and a potential reversal or uptrend may occur. Traders might consider buying or entering long positions at this point.
  3. Divergence: Divergence occurs when the direction of Williams %R differs from the direction of the price. For instance, if the price is making higher highs, but Williams %R is making lower highs, it could indicate a potential trend reversal. Divergence can help traders anticipate future price movements.
  4. Confirmation: It is often recommended to use Williams %R in conjunction with other technical analysis tools, such as trendlines, moving averages, or other momentum indicators. The confirmation from multiple indicators increases the reliability of the signals generated by Williams %R.


It is important to note that Williams %R, like any technical analysis tool, has its limitations and is not foolproof. Therefore, it is crucial to combine it with other forms of analysis and additional indicators to make well-informed trading decisions.


What are the common applications of Williams %R in trading?

Williams %R is a popular technical indicator used in trading for various purposes. Some common applications of Williams %R include:

  1. Identifying overbought and oversold conditions: Williams %R is often used to determine when a stock or other financial instrument is overbought or oversold. Readings above -20 indicate overbought conditions, meaning the price may be due for a pullback, while readings below -80 indicate oversold conditions, suggesting a potential rebound in price.
  2. Spotting trend reversals: Traders use Williams %R to identify potential trend reversals in a market. When the indicator reaches extreme levels and begins to change direction, it may signal a shift in market sentiment and the start of a new trend.
  3. Timing buy and sell signals: By using Williams %R in conjunction with other technical indicators or price patterns, traders can generate buy and sell signals. For example, a crossover of the indicator above -50 could trigger a buy signal, while a crossover below -50 could trigger a sell signal.
  4. Confirming potential breakouts or breakdowns: Traders use Williams %R to confirm breakouts or breakdowns from key levels of support or resistance. If the indicator moves in the same direction as the price breakout, it provides additional confirmation of the validity of the move.
  5. Divergence analysis: Williams %R can be utilized to identify divergences between the indicator and the price action. When the price makes a higher high but the indicator makes a lower high, or vice versa, it may indicate a potential trend reversal or a loss of momentum.
  6. Setting stop-loss and take-profit levels: Traders often use Williams %R to determine optimal levels for setting stop-loss and take-profit orders. For example, in a long position, a trader may set a stop-loss order when Williams %R crosses below -80, indicating the potential for a further decline.


It is important to note that while Williams %R can be a helpful tool in trading, it should always be used in conjunction with other indicators and analysis techniques to make well-informed trading decisions.


What is the significance of -20 and -80 levels in Williams %R?

The -20 and -80 levels in Williams %R are significant because they are commonly used as threshold levels to indicate potential overbought and oversold conditions in a security or market.


When the Williams %R indicator falls below -80, it suggests that the security or market is oversold. This means that the price has experienced a significant decline or downward movement, and there is a higher probability that the price may reverse and start to rise again. Traders and investors often interpret this as a potential buying opportunity, expecting a price rebound.


Conversely, when the Williams %R indicator rises above -20, it indicates that the security or market is overbought. This means that the price has experienced a significant increase or upward movement, and there is a higher likelihood that the price may reverse and start to decline. Traders and investors may interpret this as a potential selling opportunity, expecting a price correction.


These levels help traders and investors identify potential turning points in price trends, and they can be used in conjunction with other technical analysis tools to make more informed trading decisions. However, it's important to note that these levels are not absolute signals, and other factors should be considered before making any trading decisions.


What are the key assumptions made in Williams %R calculation?

The Williams %R calculation assumes the following key assumptions:

  1. Time period: The calculation assumes a specified time period, typically 14 periods, for which the calculation is performed. This time period is used to determine the high and low prices over that period.
  2. Market efficiency: The calculation assumes that the market is efficient, meaning that all available information is already reflected in the stock price. Therefore, it assumes that historical price data can be used to predict future price movements.
  3. Range-bound market: The calculation assumes that the market is range-bound, meaning that prices tend to fluctuate within a certain range. The Williams %R is designed to identify overbought and oversold conditions within this range.
  4. Normal distribution: The calculation assumes that price movements follow a normal distribution, with a symmetrical distribution of returns. This assumption allows for the interpretation of the Williams %R as a measure of relative strength between the recent high and low prices.
  5. Equal weighting: The calculation assumes equal weighting for all periods within the specified time period. It does not assign more weight to recent data, unlike other technical indicators such as moving averages.
  6. Constant time interval: The calculation assumes that the time interval between each data point is constant. This assumption ensures that the calculation remains consistent and accurate over the specified time period.
