Introduction to Williams %R

Developed by Larry Williams, Williams %R is a momentum oscillator widely used for its ability to identify overbought and oversold market levels and to detect momentum failures.

-Williams %R oscillates from values 0 to -100

-Williams %R shows the level of the close relative to the highest high for a particular period:

• When Williams %R is near zero (0), it shows the price is trading near the highest high (look back period)
• When Williams %R is near -100, it shows the price is trading near the lowest low (look back period)

-Similarly, the Stochastic Oscillator shows the level of the close relative to the lowest low (► more about Stochastic)

-Williams %R and the Fast Stochastic Oscillator produce the exact same reading, only the scaling is different

Calculating Williams % R

■ Williams % R = HC / HL * - 100

Where,

HC = Highest High (in R Periods) – Last Closing Price
HL = Highest High (in R Periods) – Lowest Low (in R Periods)

The Williams %R is a momentum indicator comparing closing prices to the highest high.

• Identifying overbought/oversold market levels
• Measuring and evaluating trend momentum
• Detecting momentum continuation or failure

Williams %R and the Fast Stochastic Oscillator produce the exact same reading, only the scaling is different.

Overbought/Oversold Market Levels

□ Williams % R indications from 0 to -20 are alerting overbought market levels in ranging markets. In trading markets, these levels may indicate a short correction before the trend continuous

□ Williams % R indications from -80 to -100 are alerting oversold market levels in ranging markets. In trading markets, these levels may indicate a short correction before the trend continuous

□ The Williams %R centerline (-50) is an important level

Momentum Failures

Momentum failures occur when the price of an overbought/oversold asset fails to come back into the previous overbought/oversold territory. This situation may signify a strong price movement in the opposite direction (trend reversal).
