Williams %R is a momentum indicator that shows where the latest closing price sits within its recent trading range.
It moves between 0 and -100.
A reading near 0 means price is closing near the top of its recent range.
A reading near -100 means price is closing near the bottom.
Williams %R can help identify strong momentum and possible overbought or oversold conditions. However, an extreme reading does not guarantee a reversal.

What Is Williams %R?
Williams %R is a momentum oscillator created by Larry Williams.
It compares the latest closing price with the recent high-low range.
The indicator helps answer:
Is price closing near recent highs, recent lows, or somewhere in the middle?
This makes it useful for understanding short-term momentum.
What Do Overbought and Oversold Mean?
Williams %R commonly uses two reference areas:
0 to -20: Overbought
-80 to -100: Oversold
These labels can be misleading if read too literally.
Overbought does not mean price must fall.
Oversold does not mean price must rise.
A strong trend can remain overbought or oversold for a long time.
The reading should therefore be treated as context, not a prediction.
Overbought Williams %R
Suppose Williams %R is -15.
Price is closing near the upper end of its recent range.
This can indicate strong upward momentum.
But it does not automatically mean the market is ready to reverse.
For example:
Williams %R: Overbought
Trend Strength: Strong
Exhaustion Risk: Low
This may simply reflect a healthy trend.
Now consider:
Williams %R: Overbought
Trend Strength: Strong
Exhaustion Risk: High
The trend is still strong, but it may also be stretched.
The wider context changes the meaning of the same Williams %R reading.
Oversold Williams %R
Suppose Williams %R falls below -80.
Price is closing near the lower end of its recent range.
This can indicate strong downside momentum.
However, oversold does not mean a rebound must happen.
A strong downtrend can remain oversold while price continues falling.
That is why Williams %R should be compared with the broader trend.
Williams %R Is Not a Reversal Signal
One of the biggest mistakes is assuming:
Overbought = sell
or:
Oversold = buy
Williams %R does not work that way.
An extreme reading can mean the market is stretched.
It can also mean momentum is simply very strong.
The better question is:
What is the broader trend doing?
Look at trend strength, exhaustion, persistence, timing, and risk before drawing a conclusion.
Williams %R vs Trend Strength
Williams %R and Trend Strength measure different things.
Williams %R shows where price sits inside its recent range.
Trend Strength shows how organized the broader directional move appears.
A market can have an extreme Williams %R reading while the broader trend remains weak.
It can also remain overbought during a strong and persistent trend.
This is why one indicator should not be used alone.
How to Read Williams %R
Use a simple process:
1. Check the level.
Is Williams %R near 0, near -100, or in the middle?
2. Check the trend.
Is the broader market structure strong or weak?
3. Check exhaustion.
Is the trend healthy or stretched?
4. Check persistence.
Has the move remained durable?
5. Check timing and risk.
Is the setup confirming, and what happens if it fails?
This gives Williams %R a clear role:
momentum context, not a complete trading decision.
