AB=CD — The Base Structure Behind Every Harmonic, Where You Overlay Time Symmetry on Price Symmetry

For anyone who has only measured AB=CD by price symmetry, this lays out a way to also watch the bar count where CD ends (time symmetry) and to look once more at the spot where price and time symmetry overlap. It covers why bar-time symmetry holds more cleanly in 24/7 crypto, the entry rule for the price-and-time PRZ overlap, and the fact that this base structure sits inside every harmonic.

Harmonic PRZ Patterns: Read the D Point as a Price Zone

Harmonics only become trade candidates when the PRZ width, first reaction, retest, and invalidation all line up.

PRZ Playbook: Narrowing the Zone with Confluence, Reaction, and Invalidation

Treat the PRZ as a trading plan, not just a single harmonic D-point price. Narrow it through ratio clusters, zone width, first reaction, retest, and invalidation.

Gartley Pattern: B Retracement Failure and D Reaction Decide the Trade

Read the Gartley through B-point retracement failure, PRZ confluence, and the reaction at D. Memorizing 78.6% is not enough.

Bat Pattern: Deep D, Tight Invalidation

This article breaks down the Bat pattern into a shallow B, an 88.6% D, and invalidation near X, treating it as a tight-risk setup rather than a reason to chase price.

Butterfly Pattern - Testing Exhaustion Beyond X

The Butterfly is not just a reversal setup beyond X. It should be judged by the depth of B, an extended PRZ, and whether price returns after exhaustion.

Crab Pattern: The 1.618 Extension Is Where You Start Watching for a Reversal

Treat the Crab pattern not as a deep 1.618 extension alone, but as a narrow PRZ, a fast return from overextension, and a setup to abandon quickly if it fails.
