Harmonic patterns are precise, Fibonacci-based geometries — five points (X, A, B, C, D) whose leg ratios project a Potential Reversal Zone where price is likely to turn. The terminal recognises the classic set for you and gives you tools to draw and measure them by hand.

The patterns
Each is validated against its defining Fibonacci ratios and drawn with the reversal zone marked:
- Gartley, Bat and Butterfly.
- Crab and Deep Crab.
- Cypher and Shark.
- 5-0, and the ABCD building block they share.

Draw and measure by hand
The Patterns group in the drawing toolbar has the XABCD, ABCD, Cypher and Three Drives tools. Drag each point and the leg ratios are computed for you, so you can label a pattern while it's still forming and see whether the ratios fit.

How to trade them
- Wait for the pattern to complete at point D, inside its reversal zone.
- Confirm the turn with structure or a candlestick signal before you act.
- Place risk just beyond the X point, and target the pattern's Fibonacci retracements.

A harmonic pattern is a hypothesis, not a guarantee. Trade the confirmation at the zone, not the drawing.
