# Anti-patterns Anti-patterns is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Scans swing structure for the five reciprocal-ratio harmonics (anti-Gartley, anti-Bat, anti-Butterfly, anti-Crab and anti-Cypher) using a 10-bar swing length and a 5% ratio tolerance. Completed structures are drawn with XABCD point labels, measured ratios and a completion zone box, and a BC projection cross-check filters implausible completions. - Indicator in the LuxAlgo Library, by LuxAlgo, published Jun 14, 2026. - Access: free. - Concepts: [Anti-patterns](https://www.luxalgo.com/library/concept/anti-patterns/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=ihjwa1wmaq1271q53sx0xu2l - Page: https://www.luxalgo.com/library/indicator/anti-patterns/ **Anti-patterns** brings the reciprocal-ratio harmonic suite, the [anti-patterns](https://www.luxalgo.com/library/concept/anti-patterns/), to the chart as one detector for the anti-Gartley, anti-Bat, anti-Butterfly, anti-Crab and anti-Cypher. A zigzag of 10-bar swings supplies the XABCD points, and a candidate must land its B retracement, C point and D completion inside a pattern's ratio windows, within a 5% tolerance, before anything draws. Published anti ratio tables vary between sources, so the build shows its work: labels can append the measured B retracement, D completion and BC projection so any detection can be audited against another table. ## How to Trade the Anti-patterns? - **Bullish completion (D at a trough)**: look for an upside reaction inside the completion zone; anti-patterns resolve with the newer move rather than against it. - **Bearish completion (D at a peak)**: the mirror read. - **Completion Zone box**: spans the XA-based completion level (XC-based for the anti-Cypher) and the reciprocal BC projection level, extending until a reaction swing confirms. - **Disappearing drawings**: an extending D redraws the same structure and can exit every ratio window. The removal itself is information. ## Anti-patterns Settings - **Swing Length** (default 10): pivot half-length for the swings; larger finds larger structures, confirmed later. - **Ratio Tolerance %** (default 5): allowed deviation around each ratio window, absorbing table differences. - **BC Projection Cross-Check** (default on): accepts completions only with a BC projection between 1.128 and 4.236. - **Anti-Gartley, Anti-Bat, Anti-Butterfly, Anti-Crab, Anti-Cypher** (all on by default): enable each table individually. - Style toggles cover point labels, measured ratios, the dashed triangle lines, the completion zone and the swing zigzag. ## Frequently Asked Questions ### How do anti-patterns relate to the classic XABCD patterns? Each anti replaces its parent's defining ratios with reciprocals: the [Cypher](https://www.luxalgo.com/library/indicator/cypher/) completes at 0.786 of XC, while the anti-Cypher looks toward the reciprocal 1.272 extension. The parents complete against a move; the antis complete with the emerging one. ### Which completion levels does this build use? Anti-Gartley near the 1.272 extension of XA, anti-Bat near 1.128, anti-Butterfly near the 0.786 retracement, anti-Crab near 0.618, anti-Cypher near 1.272 of XC: one reciprocal-derived table among several, with Ratio Tolerance % absorbing the differences. ### Why did a drawn pattern vanish from my chart? Until a reaction swing confirms, D is still live: if it keeps extending and leaves every ratio window, the structure no longer qualifies and its drawings are removed. Structures that resolve normally remain as history. --- Bat®, Crab®, Shark®, AB=CD® and 5-0® are registered trademarks of their owner, used here only to identify the patterns.
