MMXM Structure by Ludwig is a market structure swing mapping indicator designed for professional price action analysis. It automatically detects and marks swing highs and lows over a configurable lookback period, connecting these points with a ZigZag framework to visualize market direction and structural changes clearly. The tool highlights upper market extremities in red, indicating potential sell setups at significant resistance or exhaustion levels. It also projects body envelope extremity lines, which represent the maximum and minimum candle body reach within swings, helping traders assess price overextension before reversals.

Key features include automated swing detection without lagging repaint artifacts, ZigZag structure visualization, upper extremity markers for sell-side focus, body envelope extremities, optional extension line projection for live price tracking, precise labeling of swing points, and customizable appearance settings. Traders can use the indicator to identify potential reversal points by waiting for upper extremity markers, confirming with additional signals, and using the ZigZag trend lines and extremity levels as resistance or support references. Entry and exit levels can be set based on swing highs and lows or structural breaks.

This indicator supports analysis on markets such as Forex, XAUUSD (gold), and NAS100, and is suitable for strategies including breakout, scalping, and smart money concepts. It provides visual market structure insights to aid in trade decision-making.
