Features and specs

What each product offers, as listed by its team.

GEX Horizon 6 features
Ionic 5 features
  • 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 — 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 — call wall, put wall, zero gamma flip, and major gamma concentrations — 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.
  • Cross-Platform Development
    Ionic allows developers to build applications for multiple platforms such as iOS, Android, and the web using a single codebase. This significantly reduces development time and costs.
  • Rich UI Components
    Ionic provides a wide range of pre-built UI components that are customizable and designed to look and feel native on all devices. This makes it easier to create visually appealing and consistent interfaces.
  • Integration with Angular
    Ionic is tightly integrated with Angular, a popular and widely-used front-end framework. This integration provides a robust architecture for building complex applications.
  • Active Community and Extensive Documentation
    Ionic has an active community and extensive documentation, tutorials, and resources. This makes it easier for developers to find support and resolve issues.
  • Cordova and Capacitor Plugins
    Ionic apps can leverage Cordova and Capacitor plugins to access native device features like the camera, GPS, and file system, providing near-native functionality.

Possible disadvantages

  • Performance Issues
    Because Ionic uses WebView for rendering, performance can sometimes be inferior to native applications, particularly for highly interactive or graphically intensive applications.
  • Dependency on Third-Party Plugins
    Ionic heavily relies on third-party plugins for accessing native features. If these plugins are not well-maintained or lack support for certain functionalities, it can lead to challenges.
  • Learning Curve
    While Ionic simplifies cross-platform development, it still requires familiarity with web technologies like JavaScript, CSS, and HTML, as well as frameworks like Angular. This could be a steep learning curve for developers not versed in these technologies.
  • File Size
    Ionic applications tend to have a larger file size compared to native applications, mainly due to the inclusion of WebView and other dependencies. This can impact download times and initial load performance.
  • Rendering Delays
    There can be noticeable delays in UI rendering, especially on older devices, due to the abstraction layer that Ionic provides over native components.

Questions & Answers

As answered by people managing GEX Horizon and Ionic.

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 — we update with every options trade. Key differentiators:

  • Live zero gamma flip detection — know the exact strike where dealer positioning shifts regime in real-time, not at yesterday's close
  • Free institutional-grade analytics — call/put walls, dealer hedging velocity, and 0DTE flow are typically locked behind expensive paywalls elsewhere
  • Multi-asset coverage — SPX, SPY, QQQ, NDX plus single stocks like NVDA, TSLA, AAPL, MSFT all in one dashboard
  • No delayed snapshots — 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 — WebSocket streaming delivers sub-second GEX updates, so you see dealer positioning as it shifts, not yesterday's snapshot
  • Free institutional-grade data — Call/put walls, zero gamma flips, dealer hedging velocity, and 0DTE flow are all available at no cost — features typically locked behind expensive paywalls
  • Zero gamma flip detection — Know the exact strike where the market shifts from volatility suppression to acceleration, in real-time
  • Multi-asset in one view — SPX, SPY, QQQ, NDX plus single stocks (NVDA, TSLA, AAPL, MSFT) all tracked from a single dashboard
  • 0DTE-specific analytics — Isolate same-day gamma exposure to understand how 0DTE options are driving intraday dealer behavior and pinning forces
  • No API key or setup required — Open the dashboard and start trading. No subscriptions, no configuration, no delayed data tiers
  • Built by traders, for traders — 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 — 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 — 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 — free, real-time, and built for the traders who need it most.
