Market Structure Pillar Hub
Market structure is the blueprint of how buyers, sellers, and intermediate market makers exchange assets. Rather than observing price alone, market structure maps order book distributions, execution regimes, and risk transfers.
Why It Matters
Understanding market structure allows options traders to trace where liquidity pools reside, locate major bid/ask friction points, and identify what execution profiles (e.g. professional desks vs. retail) dominate current volumes.
Core Concepts
- Market Maker Inventories: The intermediary buffers facilitating continuous execution.
- Price Discovery: How execution matches buy/sell interest to clear spreads.
- Trend vs Range Regimes: The structural environments where volatility scales or decays.
