React Navigation VS GEX Horizon

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 — 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 — buying dips, selling rallies — suppressing volatility. When short gamma, they chase momentum — buying highs, selling lows — accelerating moves. Knowing which regime you're in is the most actionable market structure data available.

Key Capabilities

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

Pricing

Questions & Answers

As answered by people managing React Navigation and GEX Horizon.

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.

Unusual Whales vs GEX Horizon for 0DTE Options

Predicting Market Maker Behavior: If dealers are in a "Positive Gamma" regime, they will hedge by selling into rallies and buying into dips, creating a tight, low-volatility, range-bound market. If they are in a "Negative Gamma" regime, they must sell into dips and buy into rallies, exacerbating volatility. GEX Horizon quantifies this, telling you exactly how the market will...
