Bullish AB=CD Chart Pattern — How to Spot and Trade It
7/6/2026
A harmonic two-leg decline where CD mirrors AB — buyers step in at D.
In plain words
Two identical staircases down into the basement — you know where the floor is.
What the classic books say
The Bullish AB=CD is a reversal pattern with reference reliability Medium and illustrative behaviour of Symmetry completes ~60-70% (the kind of statistics catalogued in Bulkowski's encyclopedic pattern studies and Murphy's technical-analysis classic). Cornerstone of harmonic trading.
Level by level
Beginner
The second drop copies the first — and that symmetry marks where buyers plan to act.
Intermediate
CD ≈ AB in length and time; D often lands on a 61.8-78.6% retracement cluster.
Advanced
Confluence of AB=CD completion with Fib clusters and support raises the odds.
Trade plan (educational template)
- Entry: At/near D completion with a reversal candle (e.g. hammer or engulfing).
- Stop-loss: Below D by a small buffer.
- Target: 38-61.8% retrace of the whole AD move, then C.
- Check the numbers with the Risk-Reward calculator before any entry.
Common beginner mistakes
- Forcing symmetry where none exists
