Track Market Maker Positioning in Real-Time

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).

Why Gamma Exposure Matters

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.

Key Capabilities

  • Zero Gamma Flip Indicator โ€” Detect the strike where dealer positioning shifts from volatility suppression to acceleration.
  • Live SPX GEX Dashboard โ€” Real-time call/put walls, net gamma by strike, and dealer hedging levels updated with every trade.
  • 0DTE Options Flow โ€” Isolate same-day gamma to reveal how 0DTE options drive intraday dealer behavior.
  • Dealer Hedging Velocity โ€” Quantify how fast dealers must hedge. Rising velocity = escalating impact.
  • Vanna Exposure โ€” Track how IV shifts alter dealer delta, creating feedback loops beyond what gamma predicts.
  • Volatility Shock Index โ€” Composite metric assessing the probability of a regime break.

Pricing

Tier What You Get
Free Real-time GEX, call/put walls, zero gamma flip for SPX, SPY, QQQ

See the flow. Anticipate the hedge. Trade the structure.

GEX Horizon features and specs

  • Real-Time GEX Streaming
    Live sub-second WebSocket stream of net gamma exposure for SPX, SPY, QQQ, and major US equities, updated with every options trade.
  • Call Wall Detection
    Auto-identifies the strike with largest net call gamma โ€” acting as major upside resistance from heavy dealer selling pressure.
  • 0DTE Options Flow
    Intraday analytics for zero-days-to-expiration options, isolating 0DTE gamma exposure from all-expirations to reveal same-day dealer hedging impact on price action.
  • Put Wall Detection
    Automatically identifies the strike with the largest net put gamma, acting as strong downside support due to market maker delta buying obligations.
  • Live Gamma Levels Matrix
    Consolidated real-time view of key GEX levels โ€” call wall, put wall, zero gamma flip, and major gamma concentrations โ€” across all tracked underlyings in a single dashboard.
  • Dealer Hedging Velocity Index
    Measures the speed and magnitude of market maker delta hedging activity, indicating how much buying or selling pressure dealers must execute per unit of price movement.

Node.js features and specs

  • Asynchronous and Event-Driven
    Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
  • JavaScript Everywhere
    Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
  • Large Community and NPM
    Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
  • High Performance
    Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
  • Scalability
    Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
  • JSON Support
    Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages of Node.js

  • Callback Hell
    The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
  • Not Suitable for CPU-Intensive Tasks
    Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
  • Immaturity of Tools
    Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
  • Callback and Promise Overheads
    Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
  • Fragmented Ecosystem
    The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
  • Security Issues
    The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.

Questions & Answers

As answered by people managing GEX Horizon and Node.js.

What makes your product unique?

GEX Horizon's answer

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:

  • Live zero gamma flip detection โ€” know the exact strike where dealer positioning shifts regime in real-time, not at yesterday's close
  • Free institutional-grade analytics โ€” call/put walls, dealer hedging velocity, and 0DTE flow are typically locked behind expensive paywalls elsewhere
  • Multi-asset coverage โ€” SPX, SPY, QQQ, NDX plus single stocks like NVDA, TSLA, AAPL, MSFT all in one dashboard
  • No delayed snapshots โ€” WebSocket-powered streaming means you see dealer positioning as it changes, not 15 minutes ago

Why should a person choose your product over its competitors?

GEX Horizon's answer

  • Real-time, not daily โ€” WebSocket streaming delivers sub-second GEX updates, so you see dealer positioning as it shifts, not yesterday's snapshot
  • Free institutional-grade data โ€” Call/put walls, zero gamma flips, dealer hedging velocity, and 0DTE flow are all available at no cost โ€” features typically locked behind expensive paywalls
  • Zero gamma flip detection โ€” Know the exact strike where the market shifts from volatility suppression to acceleration, in real-time
  • Multi-asset in one view โ€” SPX, SPY, QQQ, NDX plus single stocks (NVDA, TSLA, AAPL, MSFT) all tracked from a single dashboard
  • 0DTE-specific analytics โ€” Isolate same-day gamma exposure to understand how 0DTE options are driving intraday dealer behavior and pinning forces
  • No API key or setup required โ€” Open the dashboard and start trading. No subscriptions, no configuration, no delayed data tiers
  • Built by traders, for traders โ€” Every feature is designed around the question: "What will dealers be forced to do next?"

How would you describe the primary audience of your product?

GEX Horizon's answer

  • 0DTE options day traders who need to know whether dealer hedging will suppress or accelerate intraday moves
  • SPX/SPY index options traders who use gamma levels as key support/resistance in their daily planning
  • Futures traders hedging ES/NQ positions who need to understand dealer delta exposure dynamics
  • Retail options traders seeking institutional-grade market structure data without paying premium subscriptions
  • Quantitative analysts monitoring real-time dealer positioning for systematic strategy signals
  • Financial advisors and PMs who want a quick daily read on whether the market is in a long-gamma or short-gamma regime

What's the story behind your product?

GEX Horizon's answer

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:

  • Expensive ($30-100+/month for daily snapshots)
  • Delayed (refreshing once per day, missing intraday regime shifts)
  • Incomplete (showing gamma charts without zero gamma flips, call/put walls, or hedging velocity)

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.
