How Options Analysis Suite Compares to SpotGamma

SpotGamma is one of the established names in dealer-positioning analytics: intraday GEX, vanna, charm coverage on SPX and major equity-index ETFs, plus an Equity Hub that extends the same metrics across thousands of single-name equities at daily cadence, with daily human-written commentary.

OAS is a comprehensive retail options analytics platform built on two foundational layers: a 17-model pricing engine (10 vanilla models: Black-Scholes, Heston, SABR, Local Volatility, Jump Diffusion via Merton / Kou / Bates, Variance Gamma, Monte Carlo, FFT, PDE, and Binomial trees; plus 7 exotic-option engines: Asian, barrier, lookback, digital, chooser, compound, and multi-asset) and a 17-Greek calculation layer, feeding eSSVI-fit IV surfaces with Dupire local-volatility extraction and 3D visualization.

That modeling foundation drives every downstream analytical surface on the platform: an FFT Scanner that calibrates 7 of those pricing models against the live volatility surface and emits per-contract Strong Buy / Buy / Weak Buy / Neutral / Weak Sell / Sell / Strong Sell signals from model-versus-market price comparison; an automated multi-model regime detector calibrating 8 models daily across 124 symbols with stress scoring; an OI-derived dealer-positioning surface (GEX, DEX, vanna, charm, vomma) with documented dealer-hedging sign conventions, live WebSocket spot repricing, and gamma-flip detection that overlaps with SpotGamma on the same primitives; 23 screeners (model-divergence, regime-stress, unusual-activity breadth, VRP, term-structure backwardation, put-skew, day-over-day change leaderboards); a 45+ strategy builder with exotic-option insight cards and aggregated Greeks across all 17 models; portfolio-level Greeks aggregation; professional-grade risk analytics (VaR, stress, tail, correlation, efficient frontier); a day-by-day backtester back to 2007 with walk-forward and parameter-sensitivity heatmaps; multi-asset coverage extending to futures, crypto with listed options, and major forex crosses; a Python SDK; and a 32-tool MCP server with native Claude / ChatGPT / Perplexity / Grok integrations.

SpotGamma is intentionally focused on dealer-positioning analytics with daily commentary; it does not include the underlying multi-model pricing engine, the FFT mispricing scanner, IV-surface fitting, the broader regime detector, a strategy builder, portfolio Greeks, risk analytics, a backtester, or the AI MCP integrations. SpotGamma's intraday cadence on the index products, human-written daily commentary, Equity Hub real-time alerts, and proprietary Dark Pool Indicator (DPI) are the differentiators in its favor.

OAS's differentiator is the depth of the analytical platform sitting on top of the pricing-and-Greeks engine, plus the published methodology and programmatic / AI access.

What SpotGamma Does Well

• Intraday dealer-positioning analytics (gamma exposure, vanna, charm) on SPX and the major equity-index ETFs (SPY, QQQ, IWM), updated multiple times per session. This is the historical heart of the SpotGamma product.
• Equity Hub: extending GEX-style analytics across approximately 3,500 individual equities and major listed products, providing single-name dealer-flow coverage that originally lived only on the index side. Equity Hub also surfaces real-time alerts on key-level breaks and gamma-regime shifts for its tracked universe.
• Dark Pool Indicator (DPI): a proprietary dark-pool positioning signal incorporated into the SpotGamma surface; a feature OAS does not have.
• A dedicated daily commentary product walking through that day's flip levels, key strikes, and dealer-hedging context, providing a strong educational layer aimed at active intraday traders.
• Established brand in the retail and prop-desk dealer-flow analytics space with a focused, opinionated product surface.
• Educational content (TRACE webinars, daily videos) that teaches the dealer-flow framing alongside the data, a meaningful share of the value for active traders learning the conceptual model.

What Options Analysis Suite Focuses On

• Dealer-flow analytics (GEX, DEX, vanna, charm) computed on end-of-day OPRA snapshots, exposed across approximately 2,000 optionable equities, 200+ ETFs, the major US equity indexes, E-mini futures, the most-liquid crypto pairs with listed options, and the major forex crosses. This is multi-asset coverage rather than equity-only.
• Full pricing-model surface (17 models) layered on top: Black-Scholes, Heston, SABR, Local Volatility, Jump Diffusion (Merton, Kou, Bates), Variance Gamma, Monte Carlo, FFT, PDE, Binomial trees, plus seven exotic-option models. Useful when the dealer-flow context needs to be combined with model-implied views or model-divergence diagnostics.
• Published methodology covering data sources, calibration techniques, dealer-positioning sign conventions, and known limitations. The platform documents what each metric means, how it's computed, and where the methodology is approximating something the public data cannot directly observe.
• Three interfaces (web app, Python SDK, MCP server) so the same analytics are reachable programmatically (for backtesting frameworks, custom dashboards, or AI-assistant queries), not only via a UI.
• Free tier with Black-Scholes pricing, all 17 Greeks, and end-of-day chain analysis on every supported ticker; no credit card required, no time limit.

Feature-by-Feature Comparison

Methodology Differences That Matter

• Update frequency vs breadth on the headline products: SpotGamma re-computes its dealer-positioning model multiple times per session on the index products (SPX, SPY, QQQ) and once per day on the broader Equity Hub universe. OAS computes once per session on the full ~2,000-name universe. Different tradeoffs depending on whether intraday tactical positioning on the indexes or end-of-day single-name research across the universe is the priority for your workflow.
• Dealer-positioning model assumptions: SpotGamma's aggregation methodology is partially proprietary, since the platform doesn't fully publish how it estimates the retail-vs-dealer split or its hedging-flow conventions. OAS's methodology is documented on the methodology page, including the standard retail-long-call assumption, sign conventions, and limitations. Both are end-of-day OPRA-based on the daily side; the calibration of "who is short and who is long" is the part where each platform makes assumptions.
• Pricing-model layer: SpotGamma doesn't include a calibrated multi-model surface, since that isn't the product's focus. OAS calibrates 17 models nightly and exposes the divergence between them, the implied volatility surfaces, and the model-divergence screener. If you want to combine "dealer is short gamma at this strike" with "model X says this strike is mispriced relative to Y," that combined view is what OAS adds and SpotGamma intentionally doesn't.
• Programmatic and AI access: SpotGamma is primarily a UI-driven product with a daily commentary layer. OAS exposes every analytic via REST API, WebSocket streaming, Python SDK, and the MCP server for AI assistants. For users building custom dashboards or feeding analytics into algorithmic systems or AI workflows, the access surface is meaningfully different.

Pricing

As of 2026-05, SpotGamma offers tiered subscriptions ranging from a basic individual plan to a professional tier, with the Equity Hub available as part of the broader subscription. OAS offers a free tier (Black-Scholes pricing, all 17 Greeks, end-of-day chain analysis), a Pro plan (all 17 models, calibrated IV surfaces, AI integrations, GEX dashboard, FFT scanner), and an API tier (REST + WebSocket access for programmatic consumers). Direct pricing comparisons depend on which features each user actually needs and which intraday cadence requirements apply; check current pricing on each provider's site at the time of evaluation.

When to Pick SpotGamma

• Active intraday SPX, SPY, or QQQ trading where multiple-times-per-session GEX updates are the deciding factor for tactical entries and exits.
• Reading focused, human-written daily commentary on dealer positioning is part of your workflow, particularly the same-day analytical narrative around flip levels and key strikes.
• You're primarily focused on equity options and don't need futures, crypto, or forex coverage.
• You don't need pricing-model coverage beyond what's relevant to dealer-flow framing; the calibrated multi-model surface isn't a core requirement.
• The educational content (TRACE webinars, daily videos teaching the conceptual model) is a meaningful share of the value you're paying for.

When to Pick Options Analysis Suite

• You need dealer-flow analytics combined with a calibrated multi-model pricing surface and divergence views: the dual-layer "where is dealer short gamma AND where do models disagree" use case.
• Your asset universe extends to futures, crypto, or forex (non-equity asset classes that SpotGamma doesn't cover).
• Programmatic access (Python SDK, REST API, or MCP server for AI assistants) is part of your workflow, whether for backtesting frameworks, custom dashboards, or AI-assistant queries.
• Published methodology and full data-source documentation matter for your research process or compliance documentation.
• Free-tier access for educational or research purposes (Black-Scholes pricing with all 17 Greeks and end-of-day chain analysis) is the right entry point before committing to a paid subscription.
• You want a strategy builder integrated with the multi-model pricing: payoff diagrams and per-leg Greeks across all 17 models.

When Either Works

• For end-of-day SPX or SPY GEX context, both platforms produce comparable values derived from the same OPRA-licensed source data.
• For learning the conceptual framework of dealer hedging, gamma exposure, and the flip-level model, both platforms have substantive educational content (different formats: SpotGamma leans video and live commentary, OAS leans written documentation).
• For broad single-name coverage at daily cadence (any large-cap optionable equity), both platforms cover the surface.

Alternatives to SpotGamma

Traders looking for alternatives to SpotGamma typically want either broader asset coverage (futures, crypto, forex), a calibrated multi-model pricing layer, or programmatic and AI-assistant access. Options Analysis Suite covers all three on top of dealer-flow analytics that overlap with SpotGamma on the equity-index and single-name surface.

Other alternatives to SpotGamma in the dealer-positioning analytics space include MenthorQ (also focused on dealer hedging across SPX with a flow-trader audience), and several flow-and-options-activity platforms (Unusual Whales, Blackbox Stocks, Tradytics) that overlap with SpotGamma on different parts of the analytics stack.
