GEX Evolution is a real-time options analytics desktop application that connects to your Schwab account and computes the full dealer Greek exposure landscape — gamma, delta, vanna, charm — across SPX, SPY, and QQQ. It shows you why price moves: where dealers are pinned, where they're forced to chase, and how hedging flows evolve through the session.

🔵 Intraday Heatmap Displays Dealer GEX, DEX, and Charm by strike. Positive GEX strikes pin price via mean-reversion hedging. Negative GEX zones amplify volatility as dealers chase. Identifies key levels and the zero-gamma line where market character flips from range-bound to trending.

🔵 Hedging Curves (Black-76 & Normal SABR) Black-76 constructs a model-consistent dealer hedging curve across the vol surface. Normal SABR (β=0) captures the steep skew and smile dynamics Black-76 misses — especially near-term. Both support SPX, SPY, and QQQ with per-symbol calibration.

🔵 Greeks Grid Tabular multi-Greek dashboard with inline color-scaled bar charts by strike. Instantly see which strikes carry the heaviest combined GEX + Vanna + Charm burden.

🔵 Strike Gravity Tracks the volume-weighted mean call and put strike intraday. Rising call centroid = upside reach. Falling put centroid = hedging acceleration. Per-symbol toggles for SPX, SPY, and QQQ.
