BAMM
By LuxAlgoMay 22, 2026
BAMM is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
BAMM automates the Bat Action Magnet Move (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 tooling.
