Dealer Positioning Pillar Hub
Dealer positioning exposes the underlying delta and gamma exposures of option market makers. Because market makers are legally required to hedge net directional delta, their position adjustments create predictable flow boundaries.
Why It Matters
Tracking dealer positioning allows traders to locate Gamma Flip zones, Dollar Delta Exposure (DEX), Dealer Stress Index levels, and Call/Put walls where price action is expected to contract or expand.
Core Concepts
- Net Gamma Exposure (GEX): The dollar exposure market makers must adjust per 1% price move.
- Dollar Delta Exposure (DEX): Cumulative directional delta held across dealer portfolios.
- Dealer Stress Index: Normalized capacity metric measuring market maker hedging strain.
- Gamma Flip Zone: The specific pivot strike where market regimes change from compression to expansion.
- Rehedging Pinning Effects: How dealer options decay forces price convergence toward high-gamma strikes.
