Harmonic Pattern Trading
Harmonic patterns use specific Fibonacci ratios to identify precise reversal zones in the market.
What are Harmonic Patterns?

Harmonic patterns are geometric price patterns based on Fibonacci numbers. They identify areas where price is likely to reverse with high precision.
The ABCD Pattern
The foundation of all harmonic patterns:
Structure
- A to B: Initial impulse leg
- B to C: Retracement (61.8-78.6% of AB)
- C to D: Extension (127.2-161.8% of BC)
- D is the potential reversal zone
Trading the ABCD
- Identify AB leg
- Wait for BC retracement
- Project CD target
- Enter at D with tight stop
- Target: return to A or C level
The Gartley Pattern

Discovered by H.M. Gartley in 1935:
Key Ratios
- B retraces 61.8% of XA
- C retraces 38.2-88.6% of AB
- D completes at 78.6% of XA
- CD extends 127.2-161.8% of BC
Why Gartley Works
- Multiple Fibonacci confluences at D
- Represents natural market rhythm
- High reward-to-risk at reversal zone
The Butterfly Pattern
Key Ratios
- B retraces 78.6% of XA
- D extends beyond X (127.2-161.8% of XA)
- Appears at market extremes
- Powerful reversal signal
The Bat Pattern
Key Ratios
- B retraces 38.2-50% of XA
- D completes at 88.6% of XA
- Very precise reversal zone
- Tight stop placement possible
The Crab Pattern
Key Ratios
- B retraces 38.2-61.8% of XA
- D extends 161.8% of XA
- Deepest extension pattern
- Most extreme reversal points
Trading Rules
Entry Strategy
- Identify developing pattern
- Calculate potential reversal zone (PRZ)
- Wait for price to reach PRZ
- Look for candlestick confirmation
- Enter with stop beyond the PRZ
Stop Loss Placement
- Place stop just beyond D point
- For Gartley: beyond 78.6% XA level
- For Butterfly: beyond 161.8% XA
- Always define risk before entering
Take Profit Targets
- TP1: 38.2% retracement of AD
- TP2: 61.8% retracement of AD
- TP3: Full retracement to A
Pattern Scanning Tips
- Use higher timeframes for reliability
- Look for Fibonacci confluence at D
- Combine with support/resistance
- Volume should confirm at reversal
- Practice pattern recognition daily
