What is a Gartley?
The Gartley is a five-point XABCD retracement pattern first sketched by H.M. Gartley in his 1935 book Profits in the Stock Market, on page 222, which is why it is also called the 222 pattern. Price makes an impulsive XA leg, pulls back to B, bounces to C, and completes at D inside the span of XA. The Fibonacci ratios that now define it were added by later harmonic-pattern authors: in the common modern reading, B retraces 0.618 of XA, C retraces 0.382 to 0.886 of AB, and D completes at the 0.786 retracement of XA, ideally where an internal AB=CD finishes as well.
Traders treat the D completion as a potential reversal zone: a cluster of ratio projections where the pullback against XA is expected to end and the original direction to resume. It is a place to evaluate a reversal with defined risk, not a promise of one; price that trades decisively beyond X invalidates the pattern, and completions fail regularly when the move against XA is strong.
How traders use it
- As a pullback entry template: after an impulsive XA leg, traders project the 0.786 XA level and the AB=CD completion, wait for price to reach the cluster at D, and look for confirmation such as a rejection candle or momentum shift before entering in the XA direction.
- For predefined risk: because D is projected in advance, stops commonly sit beyond the X point, where the pattern is objectively wrong, with initial targets at retracements of the AD swing, often the 0.382 and 0.618 levels.
- As a trend-following filter: many treatments only take Gartleys whose XA leg points with the higher-timeframe trend, using the pattern to time pullbacks rather than to call tops or bottoms.
Gartley vs neighboring harmonic patterns
Bat: Same XABCD retracement shape, different ratios: the Bat pairs a shallow B (0.50 of XA or less) with a deeper 0.886 D, while the Gartley pairs a 0.618 B with a 0.786 D. The B-point measurement usually decides the classification.
Butterfly: The Butterfly moves the 0.786 ratio to the B point and completes beyond the X extreme, typically at a 1.27 extension of XA; the Gartley completes inside the XA leg.
ABCD: The ABCD is the four-point symmetry embedded inside most Gartleys. A Gartley adds the X anchor and requires D to align with the 0.786 retracement of XA, not just with CD = AB.

Gartley FAQ
What does the 222 in the Gartley 222 pattern mean?
It is a page reference: the pattern appeared on page 222 of H.M. Gartley's 1935 book Profits in the Stock Market. The original study had no Fibonacci ratios; the 0.618 B and 0.786 D now treated as defining were added decades later by harmonic-pattern authors, so the historical 222 and the modern ratio-defined Gartley are related but not identical.
What ratios define a valid Gartley pattern?
In the common modern definition, B retraces about 0.618 of the XA leg, C retraces 0.382 to 0.886 of AB, and D completes near the 0.786 retracement of XA, ideally where an AB=CD structure also finishes. Tolerances vary by author and by detector, which is why two tools can mark different Gartleys on the same chart.
