# Corrective Leg Classifies completed counter-trend legs as corrective by scoring them against the impulse they retrace: retracement inside 0-100%, speed at most 1x, bar overlap of 50% or more, bodies no larger and travel efficiency under 50%. Confirmed legs are labeled Shallow, Typical or Deep, while a live zone tracks the developing correction with its depth and invalidation level.

From a confirmed-swing zigzag, it measures every completed counter-leg against the leg it retraces (depth, speed, bar overlap, body size and travel efficiency) and labels it corrective only when all five pass. A live zone follows the developing correction with running depth and invalidation. ## How to Trade the Corrective Leg? - **Corrective label**: a confirmed leg tagged Shallow, Typical or Deep by retracement depth, the pullback entry window within trend structure. - **Depth health**: a correction held under 38.2% speaks for the trend; crossing 61.8% fires the Deep Correction alert: sponsorship fading. - **Trend resumption**: price retaking the retraced leg's extreme terminates the correction and fires the resumption alert. - **Invalidation level**: the dotted line at the retraced leg's origin; trading through it stands setups down. ## Corrective Leg Settings - **Swing Length** (default 10): bars either side confirming the zigzag's swings. - **Min Retracement %** (default 0) and **Max Retracement %** (default 100): bounds on the share of the retraced leg given back. - **Max Speed Ratio** (default 1.0): per-bar travel cap versus the retraced leg. - **Min Bar Overlap %** (default 50): minimum average candle-range overlap. - **Max Body Size Ratio** (default 1.0): average body cap versus the retraced leg. - **Max Travel Efficiency %** (default 50): net versus summed close travel; one-way moves fail. - **Shallow Below %** (default 38.2) and **Deep Above %** (default 61.8): the health boundaries. - **Events Require Close Beyond Level** (default off): requires closes, not intrabar touches. - Display options cover leg labels, the active zone, the invalidation level, a faint swing framework, and a dashboard. ## Frequently Asked Questions ### What separates a corrective leg from an impulse leg? Anatomy, not direction. An [impulse leg](https://www.luxalgo.com/library/indicator/impulse-leg/) travels efficiently with large bodies and little overlap; a correction advances little per bar, keeps its candles overlapping and wanders, exactly the measurements this build scores. ### Why does the tracked correction ignore a completed corrective leg? A corrective leg is part of the ongoing correction, not a fresh reference: the episode keeps measuring against the retraced impulse until its extreme is retaken or its origin gives way. ### Which retracement bounds should I set? The defaults accept any partial retrace inside the retraced leg. Raising Min Retracement % (23.6 and 38.2 are common floors) skips shallow stalls; beyond the origin the move stops being corrective. ## Related indicators - [Smart Money Concepts (SMC)](https://www.luxalgo.com/library/indicator/smart-money-concepts-smc/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/smart-money-concepts-smc.md - [Structure & Trend Dashboard](https://www.luxalgo.com/library/indicator/structure-trend-dashboard/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/structure-trend-dashboard.md - [FVG + Liquidity Sweep + CISD](https://www.luxalgo.com/library/indicator/fvg-liquidity-sweep-cisd/) (Change of Character): markdown at https://www.luxalgo.com/library/indicator/fvg-liquidity-sweep-cisd.md - [MSS Sweep Fib Retrace](https://www.luxalgo.com/library/indicator/mss-sweep-fib-retrace/) (Change of Character): markdown at https://www.luxalgo.com/library/indicator/mss-sweep-fib-retrace.md - [HTF CISD Projections](https://www.luxalgo.com/library/indicator/htf-cisd-projections/) (Change of Character): markdown at https://www.luxalgo.com/library/indicator/htf-cisd-projections.md - [HTF Sweep Signals](https://www.luxalgo.com/library/indicator/htf-sweep-signals/) (Swing Failure Pattern): markdown at https://www.luxalgo.com/library/indicator/htf-sweep-signals.md - [Liquidity Structure & Order Flow](https://www.luxalgo.com/library/indicator/liquidity-structure-order-flow/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/liquidity-structure-order-flow.md - [Market Structure Break & OB Probability Toolkit](https://www.luxalgo.com/library/indicator/market-structure-break-ob-probability-toolkit/) (Break of Structure): markdown at https://www.luxalgo.com/library/indicator/market-structure-break-ob-probability-toolkit.md --- Source: https://www.luxalgo.com/library/indicator/corrective-leg/ (LuxAlgo Library).
