Market Structure- ZigZag, Break of Structure & Order Blocks

Description:

This script is an all-in-one market structure tool designed for traders who follow price action, Smart Money Concepts (SMC), or institutional order flow. It combines Order Block detection, Break of Structure (BOS), Internal Structure Shifts (CHoCH), and a ZigZag swing framework to provide a clear and actionable view of market behavior.

Break of Structure (BOS):
-Marks BOS with horizontal dotted lines when price breaks previous swing highs/lows.
-Confirms new trends and structural shifts.

Internal Structure Shifts (CHoCH-like):
-Detects early internal changes in direction before BOS.
-User-selectable logic: based on candle Open or High/Low.
-Plotted as small black triangle markers.

-Visually simplifies trend structure and major swing points.
-Tracks last swing highs/lows for BOS validation.
