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

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.

Possible disadvantages of RectifyData

  • Limited Public Information
    RectifyData has limited publicly available information about its full feature set, pricing, and capabilities, making it difficult for potential customers to evaluate the platform before engaging with sales.
  • Niche Market Focus
    As a specialized data rectification tool, it may have a narrower scope compared to broader data management platforms that offer end-to-end data lifecycle management.
  • Learning Curve
    Like many data tools, users may need time to understand the platform's features and configure it properly for their specific data quality requirements.
  • Integration Challenges
    Depending on the existing data infrastructure, integrating RectifyData with other tools and systems in the data pipeline may require additional effort and technical expertise.
  • Lesser Known Brand
    Compared to established data quality vendors like Informatica, Talend, or IBM, RectifyData is a lesser-known solution, which may raise concerns about long-term support, community resources, and proven track record.

Questions & Answers

As answered by people managing GEX Horizon and RectifyData.

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.
