What is Williams %R?

Pinpointing Market Exhaustion

Williams %R, also known as the Williams Percent Range, is a momentum oscillator that moves between 0 and -100. It measures where the current price is relative to the highest high and lowest low over a look-back period. It is designed to alert traders when a market is at an extreme, signaling that momentum has hit a limit and a reversal is likely.

Overbought (-20 to 0): The market is at the top of its recent range. Traders view this as a potential sign of selling pressure.
Oversold (-100 to -80): The market is at the bottom of its recent range. Traders view this as a potential sign of buying pressure.

Trading with Williams %R

High-Speed Reversal Signals

Williams %R is extremely fast and can sometimes be too volatile for trend-following. It works best for traders looking to "fade" (trade against) extreme moves.

The Setup: When the indicator enters the overbought zone (-20 or above) and then crosses back down below it, many traders enter short positions. Conversely, entering the oversold zone (-80 or below) and crossing back above it signals a potential long setup.

Frequently Asked Questions

How is Williams %R different from Stochastic?

They are very similar, but Williams %R is "inverted"—it uses a scale of 0 to -100, and it is usually more sensitive to recent price action than the standard Stochastic oscillator.

Can I trade Williams %R in a strong trend?

It is risky. In a powerful, extended trend, the indicator can stay in the "overbought" or "oversold" zones for an extended period, leading to premature entries that get stopped out by continued momentum.
