# BAMM BAMM is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Automates the Bat Action Magnet Move: it finds a valid Bat front half with B between 0.382 and 0.50 of XA, arms the B level as a trigger line, and on a decisive break projects the magnet leg toward the 0.886 completion. A dashboard tracks state, trigger and target prices, leg progress, and the outcome: target reached, overrun or B reclaimed. - Indicator in the LuxAlgo Library, by LuxAlgo, published May 22, 2026. - Access: free. - Concepts: [BAMM](https://www.luxalgo.com/library/concept/bamm/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=gpwsoqsb1cq5exx3prjn0qq5 - Page: https://www.luxalgo.com/library/indicator/bamm/ **BAMM** automates the Bat Action Magnet Move ([BAMM](https://www.luxalgo.com/library/concept/bamm/)) as an armed-and-triggered state machine: a 10-bar swing zigzag supplies the structure, and a valid Bat® front half (B retracing 0.382 to 0.50 of XA with C inside the AB range) arms the B level as a trigger line, with the 0.886 retracement of XA as the destination. A decisive break of B toward D (a close through it by default) is the BAMM event that starts the magnet leg. From the trigger onward the leg is managed to one of three resolutions: arrival at the 0.886 completion, an overrun close through it, or a reclaim of B against the move. A dashboard tracks state, leg direction, trigger and target prices, progress and the last outcome. ## How to Trade the BAMM? - **BAMM label at the B break**: the entry event toward D; the fill between trigger and destination shades the leg. - **✓ arrival at 0.886**: the magnet trade is done; the completion decision is a separate framework. - **Overrun**: a close through the 0.886 level hints the structure may extend as an Alt Bat toward a 1.13 completion. - **✕ B reclaimed**: a close back through the trigger invalidates the move. Before the trigger, any violation of the A extreme voids an armed setup. The projected levels are plain retracements of the XA leg, kin to classic [Fibonacci retracement](https://www.luxalgo.com/library/concept/fib-retracement/) tooling. ## BAMM Settings - **Swing Length** (default 10): pivot half-length for the swings; larger finds bigger, rarer structures. - **Min B Retracement** (default 0.382) and **Max B Retracement** (default 0.5): the B window of a valid Bat front half. - **Completion Retracement** (default 0.886): the projected magnet destination. - **Trigger Mode** (default Close beyond B): or Wick beyond B; events are evaluated on confirmed bars. - **Show Dashboard** (default on) with position and size options. - Style toggles cover point labels, the magnet leg fill and the three colors. ## Frequently Asked Questions ### How does this relate to RSI BAMM? Same magnet logic, different raw material: here the Bat's price geometry supplies trigger and destination, while [RSI BAMM](https://www.luxalgo.com/library/indicator/rsi-bamm/) substitutes an indicator structure for part of the price pattern. Both trade the trip to a probable destination instead of waiting at it. ### Is the 0.886 level a target or an entry? Strictly the leg's destination here. Arrival ends the magnet trade and begins completion-zone assessment. Whether to fade the arrival is a separate decision the outcome row leaves open. ### What voids a setup before the trigger fires? Any trade through the A extreme against the pattern. The front half is no longer valid, so the armed drawings are removed and the tool returns to idle until a new front half re-arms it. --- Bat®, Crab®, Shark®, AB=CD® and 5-0® are registered trademarks of their owner, used here only to identify the patterns.
