GEX Horizon VS Selfcommit.dev

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

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?"

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

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.
