Our Mission

Democratizing Institutional Analytics

For decades, gamma exposure data was the exclusive domain of market makers and prime brokers. The tools to interpret dealer positioning, identify gamma flip levels, and anticipate hedging-driven price moves cost hundreds of thousands of dollars per year.

ZeroGEX changes that. We built a real-time analytics engine that computes the same metrics used by institutional desks — and delivers them to every trader, at every level, through a single unified platform.

Our belief is simple: better data leads to better decisions. When retail traders can see what the market makers see, they stop being the uninformed counterparty and start trading with structural advantage.

Under the Hood

How ZeroGEX Works

A real-time data pipeline built on market microstructure principles — from options chain to actionable insight in under a second.

Options Chain Ingestion

We ingest live options chain data across all strikes and expirations for SPY, SPX, and QQQ. Open interest, volume, bid/ask spreads, and Greeks are captured tick-by-tick during market hours.

Gamma Exposure Calculation

For each strike, we compute GEX as: Gamma × Open Interest × Contract Multiplier × Spot Price². Call GEX is positive (dealers short gamma); Put GEX is negative. Net GEX is the aggregate sum across all strikes.

Key Level Detection

Gamma Flip is identified as the strike where net GEX crosses zero. Call Wall and Put Wall are the strikes with maximum gamma-weighted open interest on each side. Max Pain is computed as the expiry price minimizing total option holder value.

Flow & Signal Synthesis

Unusual options activity is flagged by comparing volume to open interest ratios and premium size versus average. Trading signals synthesize GEX regime, flow direction, and technical factors into composite scores with directional conviction levels.

Real-Time Delivery

All computed metrics are pushed to the frontend every second via an optimized API layer. The platform auto-refreshes without page reloads, so you always see current positioning without any manual intervention.

Greeks Engine

Our built-in Black-Scholes engine calculates theoretical option prices and all five Greeks — Delta, Gamma, Theta, Vega, and Charm — using live implied volatility surfaces. The Options Calculator lets you model any scenario in real time.
