What Is GEX-Metrix?

GEX-Metrix is an options analytics dashboard with free and paid sections that displays derived calculations from options data for major US equity indices and individual underlyings. It estimates dealer positioning metrics derived from options open interest and volume.

What We Calculate

• Gamma Exposure (GEX) — the rate of change of delta per 1% move in the underlying. Shows where market makers must buy/sell to stay delta-neutral.
• Zero Gamma Level — the price where total net gamma exposure crosses zero (using a Hybrid Gaussian convolution method).
• Delta Exposure (Plus) — directional market-maker exposure across strikes.
• Charm Exposure (Pro) — sensitivity of delta to time decay (∂Δ/∂t).
• Vanna Exposure (Pro) — sensitivity of delta to volatility (∂Δ/∂σ).
• Max Pain — the price at which options buyers collectively lose the most value at expiration.
• Open Interest & Volume — breakdown by call/put and strike.

Who Runs This?

GEX-Metrix is a professional-grade options analytics dashboard built and run by experts with 20+ years of trading experience and 10+ years of financial risk management coding. It is not a financial services firm, broker-dealer, or investment adviser. For questions contact [email protected].
