Williams %R

Larry Williams famously turned $10,000 into over $1.1 million in a single trading year, and the oscillator carrying his name is one of the tools he did it with. Williams %R asks one blunt question every bar: how far below the recent high did price just close?

The answer comes on an inverted scale from 0 to −100. A reading of 0 means price closed at the highest high of the lookback window; −100 means it closed at the lowest low. Everything about the indicator follows from that inversion — overbought lives near the top at −20, oversold near the bottom at −80, and the line itself is deliberately raw: no smoothing, no signal line, just the unfiltered range position of every close.

That rawness is the point. Where the Stochastic smooths its reading twice before you see it, %R shows you momentum the instant it shifts — which makes it one of the fastest exhaustion detectors you can put on a crypto chart, provided you respect what "fast" costs in noise.

What Williams %R measures

The formula is a mirror image of the stochastic %K:

%R = −100 × (highest high − close) ÷ (highest high − lowest low), over the lookback window.

If price closes at the top of its 14-bar range, the numerator is zero and %R reads 0. Close at the very bottom and it reads −100. Mathematically, %R equals the raw stochastic %K minus 100 — the same information, unsmoothed, flipped onto a negative scale.

What it is really tracking is closing strength. Sustained closes near range highs (%R hugging 0 to −20) are the signature of buyers in control; closes sagging to range lows (−80 to −100) show sellers pressing. And because there is no smoothing, %R reacts on the exact bar that closing strength changes — one bar earlier than a slow stochastic, several bars earlier than RSI.

How it works on the Crodl terminal

Crodl's Williams %R is a Rune preset that opens in its own oscillator pane with a deliberately minimal surface:

• Length: 14 — the highest-high/lowest-low lookback (adjustable 1–200). Fourteen is Williams' classic default.
• Zone lines at −20 / −50 / −80 — dashed guides marking the overbought zone, midline, and oversold zone.
• One orange line — %R itself, drawn bold with its live value tracked on the price axis. No signal line, no smoothing inputs: the preset keeps the indicator as Williams designed it.

If the market flatlines — highest high equals lowest low across the window, which real altcoin pairs do manage — the preset returns a neutral −50 instead of dividing by zero, so the plot never breaks on dead candles.

A Williams %R Context panel shows the live reading plus an oversold status flag whenever %R is below −80. Two alert conditions are built in, and both fire on zone exits rather than entries: leave_oversold when %R crosses up through −80, and leave_overbought when %R crosses down through −20. Exit-of-zone is the higher-quality event — it marks the moment stretched momentum actually lets go, not merely the moment it becomes stretched.

How traders use it in crypto

The zones read as follows — with the critical caveat that zone behavior changes with regime:

%R reading	Zone	In a range	In a strong trend
0 to −20	Overbought	Fade candidate at resistance	Normal uptrend behavior — not a short
−20 to −50	Upper neutral	Drifting bullish	Healthy pullback floor in uptrends
−50 to −80	Lower neutral	Drifting bearish	Healthy pullback ceiling in downtrends
−80 to −100	Oversold	Fade candidate at support	Normal downtrend behavior — not a long

Range-extreme reversals

Inside a defined range, %R is a precision fade tool: a push below −80 at range support followed by a cross back up through −80 is a long trigger with a natural invalidation just below the low. The Crodl alert conditions map exactly onto this pattern.

Reading trend strength from the overbought side

Williams' own counterintuitive insight: in a genuine uptrend, %R staying pinned between 0 and −20 is a strength signal, not a sell signal. Strong trends close near their highs repeatedly. Some trend traders use the failure of that behavior as their exit — when %R stops reaching −20 on rallies and starts printing lower peaks while price grinds to marginal new highs, closing strength is thinning underneath the trend.

Failure swings

A momentum divergence pattern that needs no second indicator: %R drops below −80, bounces, then on the next price low fails to reach −80 again. Sellers could not close price at range lows even on a retest — a classic early-reversal tell, and the mirror version applies at −20 for tops.

Pairing with slower tools

Because %R is raw, most traders pair it with something steadier for context: CCI or RSI for regime and divergence, %R for the entry-timing bar. If you find yourself wanting a smoothed %R with a signal line, that is literally the slow Stochastic — use it instead.

Frequently Asked Questions

What is the difference between Williams %R and the Stochastic?

Same numerator logic, two differences: %R measures distance from the high (inverted 0 to −100 scale) while %K measures distance from the low (0 to 100), and %R is unsmoothed while the slow Stochastic smooths twice and adds a %D signal line. %R = raw %K − 100. Choose %R for speed, the Stochastic for cleaner crosses.

Why is the scale negative?

Convention from Williams' original design: the indicator measures how far price closed below the range high, so the values run from 0 (at the high) down to −100 (at the low). Flip the sign mentally and it reads like any other range-position oscillator.

What are the best Williams %R settings for crypto?

The default 14 is the standard reference. Shortening to 10 or even 7 makes it a scalping trigger at the cost of more whipsaw; lengthening toward 20–28 turns it into a swing tool whose −80/−20 touches become rarer but more meaningful. Adjust the zones themselves (−10/−90) if you trade very trendy pairs where the defaults trigger too often.

Does Williams %R repaint?

No. Every value is computed from completed highs, lows, and closes. The live bar's reading updates until that bar closes, and historical values never change.
