SmartZig is a market structure visualization indicator designed for spot markets. It maps price action by analyzing candle bodies (open and close) rather than wicks, reducing noise and helping to avoid false breakouts. The indicator overlays lower timeframe (LTF) swings on higher timeframe (HTF) swings simultaneously, enabling clearer identification of market structure shifts and changes in state of delivery (CISD). Users can hide chart bars to focus solely on the ZigZag patterns.

Key features include a dual ZigZag engine that tracks fast and slow trends independently, customizable styling for colors and line thickness, and interactive history with draggable vertical anchors to explore past structural legs. It supports independent timeframe settings for LTF and HTF without switching charts and updates swings in real-time, eliminating the need for manual drawing. Additional functionalities include leg filtering to control the number of visible historical legs and a full visibility toggle to declutter the chart.

SmartZig is tagged for key levels, break of structure (BOS), liquidity sweeps and grabs, change of character (CHOCH), market structure, and support/resistance analysis. It provides a visual tool for technical analysts to read price action more accurately and confirm liquidity events based on open-close pivots. A tutorial video is available for user guidance.
