GEXFlow is a real-time options analytics dashboard. It visualizes Gamma Exposure (GEX) and Vanna Exposure (VEX) across crypto and US equity options, helping traders observe how dealer hedging structure forms around price. Read more in Documentation.
GEXFlow is built for retail and active traders who want to understand market structure through options positioning. Whether you trade crypto, US equities, or both — if you want to observe the options flow that market makers monitor for hedging, GEXFlow is for you. Basic familiarity with options concepts (strikes, expiries, Greeks) is helpful, but not required.
No. GEXFlow is a data visualization and analytics tool — we are not a financial advisor, broker, or dealer, and we are not registered as an investment advisor under the Korean Capital Markets Act or any other jurisdiction.
The AI market analysis feature interprets GEX/VEX structure and identifies key levels, but this is informational only and does not constitute trading signals, investment advice, or recommendations. All trading decisions are your own responsibility.
Constellation is GEXFlow's signature view — a time-axis visualization that overlays GEX and VEX directly on the candlestick chart. Strikes appear as orbs across price and time. Background intensity reveals how gamma pressure shifts hour by hour, expiry by expiry. It's how you see options structure form, breathe, and dissolve in real time. Available on Premium plans.
Prism is a contract-level flow analyzer. Where Heatmap and Constellation show aggregate structure, Prism breaks options flow down trade by trade. It detects block trades, multi-leg structures, sweeps, and volume surges in real time — revealing not just what's positioned, but who is moving size and how.
Currently in Early Beta. The full version launches alongside OPRA tick data integration. Available on Premium plans.
Standard mode isolates only the most significant strikes — gamma walls, flip zones, peak Vanna concentrations — and dims the rest. Best for quickly identifying the key levels that matter most.
Discovery mode shows the full GEX/VEX heatmap across all strikes, with intensity proportional to exposure — best for seeing the complete structural map.
Toggle between them anytime above the chart.

All market data is sourced directly from exchanges or through licensed exchange vendor partnerships. Data is processed through our proprietary GEX/VEX calculation engine.
Updates run on a 1-minute interval for major instruments, and 3-minute intervals for smaller individual stocks.
Free — crypto data delayed by 15 minutes.

Premium — real-time across all instruments.
Crypto: BTC, ETH, SOL, XRP — full options chain.
US Equities: 100+ instruments including SPX, NDX, VIX, SPY, QQQ, IWM, GLD, SLV, USO, plus AAPL, NVDA, TSLA, and Nasdaq 100 components.
Global Indices (roadmap): KOSPI 200 is planned, with Hang Seng, Nikkei, and NIFTY to follow.
Market GEX is the aggregate gamma exposure across all options participants — the total positioning that exists in the market, calculated from open interest using standard call/put conventions.
This is what GEXFlow's Heatmap displays by default. It shows where structural pressure builds across strikes, regardless of who holds the positions.
Dealer GEX goes one step deeper than Market GEX — isolating just market makers' positioning rather than aggregate market exposure. Coming soon.
Not yet. GEXFlow does not currently offer a public API.
API access is on our roadmap for traders and developers who want to integrate GEX/VEX data into their own systems, dashboards, or strategies.
