Understanding Williams %R

Williams %R is a momentum indicator developed by Larry Williams that measures overbought and oversold levels in a market. It is designed to help traders identify potential reversals by comparing the current price to the price range over a specified period.

What is Williams %R?

Williams %R is a type of momentum oscillator that quantifies the relationship between the highest high and the closing price over a specified period. It oscillates between 0 and -100, where readings closer to 0 indicate overbought conditions and readings closer to -100 indicate oversold conditions.

How is Williams %R Calculated?

Williams %R is calculated using the following formula:

%R = [(Highest High - Close) / (Highest High - Lowest Low)] * -100

Where:

• Highest High is the highest price over the specified period.
• Lowest Low is the lowest price over the specified period.
• Close is the most recent closing price.
