Direct Answer
Chande Kroll Stop is a trend measure used to describe trend direction, persistence, strength, or a smoothed price reference. The production page must define the exact calculation convention before interpreting higher or lower readings, because platform and provider implementations can differ.
Chande Kroll Stop: Formula, Meaning, Signals, Examples and How to Use It
How Is Chande Kroll Stop Calculated?
A volatility-based trailing stop study by Tushar Chande and Stanley Kroll. It builds preliminary stops from the highest high and lowest low offset by a multiple of ATR, then takes the extreme of those stops over a second window.
Formula: First high stop = Highest High(p) - x*ATR(p); first low stop = Lowest Low(p) + x*ATR(p); stop short = highest of first high stop over q bars; stop long = lowest of first low stop over q bars
Inputs:
- High, low and close prices
- ATR period and highest/lowest window p
- ATR multiplier x
- Stop smoothing window q
Worked example. With a highest high of 110, an ATR of 2 and a multiplier of 1, the first high stop is 108.00. The inputs are illustrative numbers, not market data.
Reading it. The stop lines trail price at a distance scaled to volatility, and a close beyond a stop line is read as a potential change in trend direction. Wider multipliers give more room and fewer stop-outs.
Limits. Settings strongly change how often it triggers and there is no universally correct choice. In choppy markets a volatility stop is hit repeatedly, and gaps can pass through a stop level.

What is Chande Kroll Stop?
Chande Kroll Stop is a trend measure used to describe trend direction, persistence, strength, or a smoothed price reference. The production page must define the exact calculation convention before interpreting higher or lower readings, because platform and provider implementations can differ.
For Swoopr, the canonical profile separates definition, calculation, interpretation and decision use. That keeps readers from collapsing a descriptive metric into a trading strategy. An indicator can describe trend, momentum, volatility, participation, positioning or risk without providing a complete entry, exit, sizing or portfolio decision.
What does it measure?
Chande Kroll Stop measures specific market properties in the Trend domain. The practical value is repeatability: the same inputs and formula can be applied across a defined dataset, allowing users to compare readings through time or across instruments when the calculation convention is held constant.
How to read Chande Kroll Stop
Interpretation depends on the market property being measured. A descriptive reading is not automatically predictive. The same numerical state can lead to different outcomes in a strong trend, quiet range, event-driven gap or illiquid market. Always combine with context from price structure, volume, and broader market regime before drawing conclusions.
Strengths
- ATR offsets scale the stop distance to recent bar ranges, so the stop widens when volatility rises and tightens when it falls.
- The second window takes the extreme of the preliminary stops, which keeps the line from retreating on a single quiet bar.
- Reproducible when the formula and data convention are fixed.
Weaknesses and limitations
- Two windows p and q plus the multiplier x give three free settings, so many combinations fit the same past data.
- Because it is built from highs and lows, a single wide-range bar raises ATR and widens the stop distance for the following bars.
- Correlated indicators can create false confidence by repeating the same underlying information.

Frequently Asked Questions
Is Chande Kroll Stop a buy or sell signal?
No. The stop lines trail price at a distance scaled to volatility, and a close beyond a stop line is read as a potential change in trend direction. Settings strongly change how often it triggers and there is no universally correct choice. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions.
What is the best setting for Chande Kroll Stop?
Chande Kroll Stop takes these inputs: high, low and close prices; ATR period and highest/lowest window p; ATR multiplier x. There is no universal best setting for the tunable ones, so test them across instruments, regimes and out-of-sample periods and favor stable parameter regions over one historical winner.
Can Chande Kroll Stop be used by itself?
Settings strongly change how often it triggers and there is no universally correct choice. In choppy markets a volatility stop is hit repeatedly, and gaps can pass through a stop level. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone.
Does Chande Kroll Stop work on every timeframe?
The calculation (First high stop = Highest High(p) - x*ATR(p); first low stop = Lowest Low(p) + x*ATR(p); stop short = highest of first high stop over q bars; stop long = lowest of first low stop over q bars) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it.
Why does Chande Kroll Stop give false signals?
Two windows p and q plus the multiplier x give three free settings, so many combinations fit the same past data. Because it is built from highs and lows, a single wide-range bar raises ATR and widens the stop distance for the following bars. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated.
How should Chande Kroll Stop be backtested?
Rebuild Chande Kroll Stop from high, low and close prices using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
