Features and specs

What each product offers, as listed by its team.

NumPy 5 features
GEX Horizon 6 features
  • Performance
    NumPy operations are executed with highly optimized C and Fortran libraries, making them significantly faster than standard Python arithmetic operations, especially for large datasets.
  • Versatility
    NumPy supports a vast range of mathematical, logical, shape manipulation, sorting, selecting, I/O, and basic linear algebra operations, making it a versatile tool for scientific and numeric computing.
  • Ease of Use
    NumPy provides an intuitive, easy-to-understand syntax that extends Python's ability to handle arrays and matrices, lowering the barrier to performing complex scientific computations.
  • Community Support
    With a large and active community, NumPy offers extensive documentation, tutorials, and support for troubleshooting issues, as well as continuous updates and enhancements.
  • Integrations
    NumPy integrates seamlessly with other libraries in Python's scientific stack like SciPy, Matplotlib, and Pandas, facilitating a streamlined workflow for data science and analysis tasks.

Possible disadvantages

  • Memory Consumption
    NumPy arrays can consume large amounts of memory, especially when working with very large datasets, which can become a limitation on systems with limited memory capacity.
  • Learning Curve
    For users new to scientific computing or coming from different programming backgrounds, understanding the intricacies of NumPy's operations and efficient usage can take time and effort.
  • Limited GPU Support
    NumPy primarily runs on the CPU and doesn't natively support GPU acceleration, which can be a disadvantage for extremely compute-intensive tasks that could benefit from parallel processing.
  • Dependency on Python
    Since NumPy is a Python library, it depends on the Python runtime environment. This can be a limitation in environments where Python is not the primary language or isn't supported.
  • Indexing Complexity
    Although NumPy's slicing and indexing capabilities are powerful, they can sometimes be complex or unintuitive, especially for multi-dimensional arrays, leading to potential errors and confusion.
  • 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.

Questions & Answers

As answered by people managing NumPy 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.
