Features and specs

What each product offers, as listed by its team.

GEX Horizon 6 features
Opalstack 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.
  • Developer-Friendly Hosting
    Opalstack is designed with developers in mind, offering SSH access, Git integration, and support for multiple programming languages and frameworks including Python, Node.js, Ruby, and PHP, giving developers granular control over their hosting environment.
  • Affordable Pricing
    Opalstack offers competitive pricing for shared and managed hosting plans, making it an accessible option for small businesses, freelancers, and individual developers who need robust features without enterprise-level costs.
  • Modern Control Panel
    Opalstack provides a clean, modern, and intuitive web-based dashboard for managing sites, applications, databases, and email accounts, which is a significant improvement over older-style hosting control panels like cPanel.
  • Strong Support for Multiple Applications
    The platform supports a wide variety of application types including WordPress, Django, Flask, Express, static sites, and more, allowing users to host diverse projects on a single account with easy deployment.
  • Reliable Infrastructure and Support
    Opalstack is built by former WebFaction team members, bringing experienced hosting expertise. They offer responsive customer support and a reputation for stable, well-managed server infrastructure with good uptime.

Possible disadvantages

  • Smaller Community and Ecosystem
    Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
  • Limited Scalability Options
    Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
  • Not Ideal for Beginners
    While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
  • Limited Data Center Locations
    Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
  • Fewer Managed Services and Add-ons
    Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.

Questions & Answers

As answered by people managing GEX Horizon and Opalstack.

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.
