Minor Break of Structure (Minor BoS)

This indicator extracts and isolates the Minor Break of Structure (BoS) logic from a full SMC framework and presents it as a clean, lightweight tool for structure-based price action traders.

Unlike traditional BOS indicators that rely on swing calculations with heavy filtering, this script uses original SMC-style minor structure logic to detect meaningful shifts in internal order flow.
A Minor BoS appears when price breaks above a minor swing high (bullish) or below a minor swing low (bearish), confirming a short-term continuation in trend direction.

Features:

Bullish Minor BoS detection

Bearish Minor BoS detection

Automatic line plotting with extend-right

Clear “Minor BoS” label with tiny footprint

Customizable line styles and colors

Lightweight & optimized for fast execution

Zero repainting on BoS confirmations

This tool is ideal for traders who want a simple, clean, and reliable structure-based signal without the noise of major structure, order blocks, liquidity sweeps, or external SMC modules.
