Harmonic Patterns Trading — Complete Guide
Master harmonic pattern trading: Gartley, Butterfly, Bat, Crab, and Cypher patterns. Learn precise Fibonacci ratios, entry rules, and pattern identification.
What Are Harmonic Patterns?
Harmonic patterns are advanced chart patterns defined by precise Fibonacci ratios between price swings. They identify potential reversal zones (PRZ) with mathematical precision, offering high-probability trading setups.
Harmonic patterns provide exact entry levels, stop losses, and targets based on Fibonacci mathematics — removing subjectivity from pattern trading.
Pattern Structure: XABCD
All harmonic patterns consist of 5 points (X, A, B, C, D) forming specific Fibonacci relationships:
B
/ \
/ \ D (PRZ - Entry point)

Major Harmonic Patterns
1. Gartley Pattern (Most Common)
| Leg | Fibonacci Ratio |
|---|---|
| AB | 61.8% retracement of XA |
| BC | 38.2%-88.6% retracement of AB |
| CD | 127.2%-161.8% extension of BC |
| XD | 78.6% retracement of XA |
Entry: At point D (78.6% of XA) Stop: Beyond X Target 1: 38.2% of AD Target 2: 61.8% of AD
2. Butterfly Pattern
| Leg | Fibonacci Ratio |
|---|---|
| AB | 78.6% retracement of XA |
| BC | 38.2%-88.6% retracement of AB |
| CD | 161.8%-261.8% extension of BC |
| XD | 127.2%-161.8% extension of XA |
Entry: At point D (127.2% extension of XA) Stop: Beyond 161.8% of XA
3. Bat Pattern
| Leg | Fibonacci Ratio |
|---|---|
| AB | 38.2%-50% retracement of XA |
| BC | 38.2%-88.6% retracement of AB |
| CD | 161.8%-261.8% extension of BC |
| XD | 88.6% retracement of XA |
Entry: At point D (88.6% of XA) Stop: Beyond X
4. Crab Pattern
| Leg | Fibonacci Ratio |
|---|---|
| AB | 38.2%-61.8% retracement of XA |
| BC | 38.2%-88.6% retracement of AB |
| CD | 224%-361.8% extension of BC |
| XD | 161.8% extension of XA |
Entry: At point D (161.8% extension of XA) Stop: Beyond 224% of XA
Trading Rules
Entry:
- Identify the XABCD structure
- Verify Fibonacci ratios for each leg
- Wait for price to reach Point D (PRZ)
- Look for reversal candlestick confirmation
- Enter with stop beyond the pattern
Stop Loss:
- Gartley: Beyond point X
- Butterfly: Beyond 161.8% XA extension
- Bat: Beyond point X
- Crab: Beyond 200% XA extension
Targets:
- Target 1: 38.2% retracement of AD
- Target 2: 61.8% retracement of AD
- Target 3: Point A level (full retracement)
Pattern Identification Tips
- Use indicators — Harmonic pattern scanners help identify formations
- Verify ratios — All legs must match within 2-5% tolerance
- Confluence — Pattern at key S/R or with other signals = higher probability
- Timeframe — H4 and D1 patterns more reliable than lower timeframes
- Patience — Wait for D point, don't anticipate
Harmonic patterns have a ~60-70% success rate when properly identified. Always use stop losses — failed patterns can move aggressively against you.
