ZigZag ATRZigZag ATR Library
A volatility-adaptive ZigZag indicator that uses Average True Range (ATR) instead of fixed percentage deviation to detect pivot points. This makes the ZigZag dynamically adjust to market conditions — tighter during low volatility, wider during high volatility.
Why ATR instead of Percentage?
The standard ZigZag uses a fixed percentage threshold (e.g., 5%) to determine when price has reversed enough to form a new pivot. This approach has limitations:
A 5% move means very different things for a $10 stock vs a $500 stock
During high volatility, fixed percentages create too many pivots (noise)
During low volatility, fixed percentages may miss significant structure
ATR-based deviation solves these issues by measuring reversals in terms of actual volatility , not arbitrary percentages.
Key Features
Volatility-adaptive pivot detection using ATR × multiplier threshold
Automatic adjustment to changing market conditions
Full customization of ATR length and multiplier
Optional line extension to current price
Pivot labels showing price, volume, and price change
Clean library structure for easy integration
Settings
ATR Length — Period for ATR calculation (default: 14)
ATR Multiplier — How many ATRs price must move to confirm a new pivot (default: 2.0)
Depth — Bars required for pivot detection (default: 10)
Extend to Last Bar — Draw provisional line to current price
Display options — Toggle price, volume, and change labels
How to Use
import YourUsername/ZigZagATR/1 as zz
// Create settings
var zz.Settings settings = zz.Settings.new(
14, // ATR length
2.0, // ATR multiplier
10 // Depth
)
// Create ZigZag instance
var zz.ZigZag zigZag = zz.newInstance(settings)
// Calculate ATR and update on each bar
float atrValue = ta.atr(14)
zigZag.update(atrValue)
Exported Types
Settings — Configuration for calculation and display
Pivot — Stores pivot point data, lines, and labels
ZigZag — Main object maintaining state and pivot history
Exported Functions
newInstance(settings) — Creates a new ZigZag object
update(atrValue) — Updates the ZigZag with current ATR (call once per bar)
lastPivot() — Returns the most recent pivot point
Recommended Multiplier Values
1.0 - 1.5 → More sensitive, more pivots, better for scalping
2.0 - 2.5 → Balanced, good for swing trading (default)
3.0+ → Less sensitive, major pivots only, better for position trading
Based on TradingView's official ZigZag library, modified to use ATR-based deviation threshold.
