ZigZag
Pivot point identification by percentage deviation
Overview
ZigZag identifies significant price swings by filtering out noise below a specified percentage threshold. When price moves 5% (or user-specified %) from last pivot, ZigZag draws a line. Smaller intraswing moves ignored. Charts appear "compressed" showing only material moves = cleaner pattern analysis. Eliminates false breakouts caused by micro-reversals; reveals true swing structure.
Used by Elliott Wave and harmonic traders to identify wave counts accurately. ZigZag prevents over-trading small bounces; focuses on significant structure. Integrates seamlessly with pattern recognition (Head and Shoulders, Triangles, Channels). Many institutions use ZigZag preprocessing before pattern analysis. Extremely simple indicator (1 parameter) with mechanical, objective output.
Critical for swing traders, pattern traders, and Elliott Wave analysis. ZigZag removes subjectivity from identifying swing points; strictly mechanical deviation-based approach.
Formula
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Deviation % | Percent | 5% | Minimum price move to form new pivot; filters noise |
| Lookback Bars | Integer | 50 bars | Historical bar window for swing definition |
| Show Pivots | Boolean | True | Mark pivot points with small circles on chart |
Common Use Cases
1. Elliott Wave Analysis
ZigZag consolidates: Elliott Wave traders count waves accurately. 5/3 wave patterns clear on ZigZag; hidden on raw chart.
2. Chart Pattern Recognition
Head/Shoulders, Triangles, Channels appear clearly on ZigZag. Pattern lines = trendlines connect ZigZag lows/highs.
3. Swing Point Identification
ZigZag pivots = exact swing points. Use for stop placement, support/resistance, harmonic ratios.
4. Noise Filtering
Removes intraswing noise below deviation threshold. Cleaner swing structure reveals true direction bias.
Advantages & Limitations
✓ Advantages
- Mechanical Objective: 100% repeatable; no interpretation. Computer-generated pivots.
- Noise Reduction: Filters micro-moves; reveals macro structure traders care about.
- Pattern Clarity: Technical patterns (H&S, triangles) appear clearly; easy analysis.
- Wave Counting: Elliott Wave analysis accurate; prevents miscounting from noise.
! Limitations
- Lag On Pivot Completion: New pivot only appears after 5% deviation; entry delayed.
- Retroactive Redrawing: Prior pivots can shift on new data; patterns unstable.
- Parameter Sensitivity: 5% deviation changes patterns; no universal "correct" setting.
- Not Trading Signal: Indicator only; requires additional signal (pattern, price action).
Tips & Best Practices
📊 Adjust for Instrument
Stocks: 4-7% deviation. Crypto: 5-10%. Forex: 0.5-1%. Match instrument volatility.
⚡ Use as Preprocessor
ZigZag best used to filter price for pattern analysis. Not standalone trading signal; combine with patterns.
🎯 Layer with Confluence
ZigZag pivot + price action (FVG, Order Block) + pattern = strong signal. Never trade ZigZag pivot alone.
⚠️ Monitor Redrawing
Recent pivots can shift as new bars update. Do NOT trade pivots from last 2-3 bars; wait for confirmation.
Example Strategy
1. Plot ZigZag on Daily
Daily chart: set deviation to 5%. Identify last 3-5 pivots (highs/lows) where ZigZag changes direction.
2. Draw Trendline
Connect lowest ZigZag pivots = uptrend line support. Connect highest = downtrend line resistance.
3. Wait for Pattern
Watch if recent ZigZag pivots form chart pattern (triangle compression, channel, H&S forming).
4. Trade Pattern Breakout
When price breaks ZigZag-defined pattern on volume = entry. Stop = prior ZigZag pivot. Target = next ZigZag level.
