Markets — Pattern Detection Overview

The ohlc-service detects three families of patterns from OHLC candlestick data. All detection begins with swing-point extraction; harmonic and structure patterns are built directly on those pivots, while candlestick patterns operate on raw candle bodies and wicks.

Pattern Families

Family	Description	Patterns
Harmonic	5-point XABCD structures defined by Fibonacci ratios	Gartley, Bat, Butterfly, Crab, Shark, Cypher
Structure	Multi-swing price-action formations	ABCD, Three Drives, Double Top/Bottom, Head & Shoulders
Candlestick	Single-, two-, and three-candle reversal signals	Hammer, Doji, Engulfing, Morning/Evening Star, 3 White Soldiers, and more
