GEX Horizon is a free, real-time Gamma Exposure (GEX) analytics platform for options traders who need to see where dealers are positioned โ and what they'll be forced to do next.
Unlike legacy GEX tools that refresh daily, GEX Horizon delivers sub-second WebSocket streaming of net gamma exposure across SPX, SPY, QQQ, NDX, and equities (NVDA, TSLA, AAPL, MSFT, IWM).
When market makers are long gamma, they trade against the trend โ buying dips, selling rallies โ suppressing volatility. When short gamma, they chase momentum โ buying highs, selling lows โ accelerating moves. Knowing which regime you're in is the most actionable market structure data available.
| Tier | What You Get |
|---|---|
| Free | Real-time GEX, call/put walls, zero gamma flip for SPX, SPY, QQQ |
| Pro | Tick-level data, vanna, volume-profile GEX, more underlyings |
| Institutional | Full API, custom underlyings, bulk exports, dedicated support |
See the flow. Anticipate the hedge. Trade the structure.

GEX Horizon is the only free platform that delivers real-time, sub-second gamma exposure data via WebSocket streaming. Most GEX tools update once daily โ we update with every options trade. Key differentiators:

GEX Horizon was built out of frustration with the status quo in options analytics. Institutional traders have always had access to real-time gamma exposure data โ it's fundamental to understanding market maker behavior and intraday volatility regimes. Yet the tools available to most traders were either:
We believed that every trader deserves to see where the dealers are positioned โ in real-time, without a paywall. So we built the WebSocket infrastructure, the real-time GEX computation engine, and the intuitive dashboards that make institutional-grade options market microstructure data accessible to everyone. The result is GEX Horizon โ free, real-time, and built for the traders who need it most.

After starting the project called socketify.py at https://github.com/cirospaciari/socketify.py, I got pretty good results and reviews, but many people asked if socketify.py could be used to create a WSGI and ASGI server. WSGI and ASGI have a lot of overhead, that's is why I choose not to use them in the first place, but adding an ASGI and WSGI server allows a lot of code already written to run faster!
