How Options Analysis Suite Compares to ORATS
ORATS is one of the established institutional options data vendors, with roots going back to 2001. The core product is a high-quality options data feed: cleaned and gap-filled OPRA chains, SMV-smoothed IV surfaces (ORATS's branded smoothing methodology), dividend forecasts, earnings-move databases, and historical analytics intended for hedge funds, prop shops, quant researchers, and sophisticated retail. ORATS is a data layer many other tools consume for end-of-day chains.
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) and a 17-Greek calculation layer. OAS sources institutional-grade end-of-day chain data, so on the underlying chain quality, the platforms operate at comparable depth.
Both companies sell an end-user application, so the distinction is what each one builds on top of the data rather than whether a front end exists at all. ORATS's Trading Tools is organised around its own data products: scanners ranked on the smoothed surface, parameterized backtests, trade construction, position monitoring and Profit Attribution. OAS is organised around a calibrated multi-model pricing layer and the surfaces derived from it: dealer-positioning views (GEX, DEX, vanna, charm), the FFT mispricing scanner, the multi-model regime detector, 23 screeners including model-divergence, the 45+ strategy builder, portfolio Greeks, risk analytics, the day-by-day backtester, a Python SDK, and a 32-tool MCP server for AI assistants. Both surface high-quality OPRA-derived end-of-day chains; what differs is which analytics sit on them.
ORATS's differentiators are institutional-grade data quality (SMV smoothing produces cleaner surfaces than raw OPRA, gap-filling fixes the holes that real-data integrations have to handle), a long historical dataset with stable methodology, and a dividend forecast service. ORATS also ships a full retail-facing trading application at the same $99/month price point OAS competes at, which an earlier version of this page did not reflect: Trading Tools, Trade Builder, Option and Stock Scanners, an Options Backtester, a Strategy Optimizer, Profit Attribution, order routing through Interactive Brokers / TradeStation / Tradier, an MCP server, and Otto, a natural-language agent over 95 platform tools.
OAS's differentiator is the analytics layer it puts on the data: extended-SVI (eSSVI) surface fits in the same family of smoothed-surface methodologies, plus model-divergence views, dealer-flow analytics, and screeners that operate on the calibrated surface directly. Where ORATS expresses its analytics in terms of the SMV surface, dividend forecasts and historical studies, OAS expresses them as disagreement between 17 calibrated models.
Comparison information current as of 2026-08. Competitor pricing and features change; treat the specifics in this page as a snapshot from that month, not a real-time read.
What ORATS Does Well
- Cleaned, gap-filled OPRA chain data with SMV-smoothed IV surfaces - institutional-grade data quality used by hedge funds, prop shops, and quant researchers as a primary feed.
- Long historical dataset (chains, IV surfaces, dividends) with stable methodology, useful for serious backtesting where data-quality consistency matters.
- Dividend forecast service: ORATS publishes dividend forecasts for equity options, where dividend-adjustment errors materially affect pricing.
- Backtesting at scale: 300M+ precomputed backtests, 2,000 custom backtests per month included in Trading Tools, an Intraday Backtester covering 0DTE back to October 2020, and a Strategy Optimizer with p-values, permutation testing and Monte Carlo simulation.
- Two delivery channels: a REST Data API for teams integrating chains and surfaces into their own systems, and Trading Tools, a $99/month web application for users who want ORATS's analytics without building anything themselves.
- Earnings-move database with statistical models for expected move that's widely cited in research.
What Options Analysis Suite Focuses On
- End-user platform that integrates institutional-grade end-of-day options data into ready-to-use analytics surfaces: GEX/DEX dealer-positioning views, FFT mispricing scanner with multi-model buy/sell signals, multi-model regime detector, 23 screeners, 45+ strategy builder.
- 17-model pricing engine (10 vanilla + 7 exotic) with calibration to the live chain. ORATS's focus is data and SMV smoothing; OAS focuses on the multi-model pricing layer that sits on top.
- Three interfaces (web app, Python SDK, MCP server) over one analytics surface. ORATS ships a web app alongside its API too, so the difference is the shape of the interfaces rather than whether a browser UI exists: the OAS Python SDK is first-party, and the MCP server exposes the analytics surface rather than data retrieval.
- Free tier with Black-Scholes pricing, all 17 Greeks, and end-of-day chain analysis on every supported ticker. ORATS is paid-only.
- AI-assistant integration via the 32-tool MCP server: Claude, ChatGPT, Perplexity, and Grok can query analytics directly. ORATS also ships an MCP server (an npm CLI wrapping 26 endpoints, supporting Claude Code and Codex) plus Otto, its own natural-language agent over 95 platform tools, so this is a difference of scope rather than presence.
Feature-by-Feature Comparison
| Feature | ORATS | Options Analysis Suite | Notes |
|---|---|---|---|
| OPRA chain data quality | Cleaned, gap-filled, SMV-smoothed; institutional-grade | Institutional-grade OPRA-derived end-of-day chain data | On end-of-day chain accuracy and IV surface fitting, the platforms operate at comparable data depth. |
| IV surface methodology | SMV smoothing (ORATS's branded methodology) | eSSVI fit + Dupire local-vol extraction + 17-model calibration | OAS extends the SVI/SSVI family with multi-model calibration and local-vol extraction; ORATS's SMV is its branded smoothed-surface fit. |
| Historical depth | Long historical dataset with stable methodology | Daily analytics snapshots and day-by-day backtester history back to 2007 | Corrected 2026-08: us previously said "live snapshots from 2024+", which contradicted AboutPage / page.ts claims and the snapshot-history backfill (proxy/scripts/snapshot-history-backfill.ts from 2007-01-01) that feeds Greeks/IV/GEX history. ORATS still wins on methodology-stability branding; depth to 2007 is shared. |
| Dividend forecasts | Yes, a published forecast service | Standard dividend adjustments; not a forecast product | ORATS's dividend forecasts are a recognized strength; OAS uses standard ex-dividend adjustments without an independent forecast layer. |
| Backtester | Yes, parameterized strategy testing; the Options Backtester and an Intraday Backtester are bundled into the $99/month Trading Tools package (2,000 custom backtests per month) | Yes (day-by-day back to 2007, walk-forward, parameter sensitivity heatmaps, multi-asset) | Corrected 2026-08: this row previously called ORATS's backtester a "standalone product", which contradicted this entry's own pricingNote saying it is included in Trading Tools and not priced separately. Both have backtesters; ORATS's is more research-oriented (parameterized studies), OAS's is more strategy-oriented (45+ pre-built structures). |
| Multi-model pricing engine | Limited (focus is data, not model implementations) | 17 models: Black-Scholes, Heston, SABR, Local Vol, Jump Diffusion (Merton, Kou, Bates), Variance Gamma, Monte Carlo, FFT, PDE, Binomial, plus 7 exotics | Different product scope. ORATS provides surface fits as a data product; OAS independently calibrates a multi-model layer against institutional-grade chain data. |
| Dealer-positioning analytics (GEX, DEX, vanna, charm) | Data primitives available; analytics layer not built in | Full dealer-positioning surface across ~2,000 tickers | On ORATS, building dealer-flow analytics requires integrating the chain data into a custom analytics layer; OAS ships the ready-built surface. |
| FFT mispricing scanner | No | Yes (7-level signal system across 7 calibrated models) | OAS-specific applied output of the multi-model engine. |
| Multi-model regime detector | No | Yes (8 models calibrated daily across 124 symbols with stress scoring) | Automated longitudinal regime classification. |
| Screeners | Yes: an Option Scanner over 5,000+ symbols ranked by D%/POP%, and a Stock Scanner over 5,000+ stocks and ETFs using 700+ option indicators | Yes (23 screeners: model-divergence, regime-stress, VRP, put-skew, etc.) | Pre-built screening views that operate on the calibrated surface. |
| Strategy builder | Yes: Trade Builder supports bullish, bearish and neutral structures with custom multi-leg scans and a payoff diagram including Greeks | Yes (45+ strategies with aggregated Greeks across all 17 models) | Different product scope. |
| Portfolio Greeks + risk analytics | Yes: position monitoring, "what if" scenarios, paper trading, alerts, and Profit Attribution decomposing Greeks, skew and theoretical value per trade and across the portfolio | Yes (VaR, stress, tail risk, correlation, efficient frontier) | Position-management surface. |
| Python SDK | No first-party Python SDK. The `orats` PyPI package is a third-party GPLv3 client at 0.1.1a0 alpha with no release in 12+ months; ORATS delivers via REST and an npm CLI | Yes (pip install options-analysis-suite) | Corrected 2026-08: an earlier version over-credited ORATS here by treating API-first design as an SDK. |
| REST API access | Yes (core delivery channel) | Yes (on API tier) | ORATS's API is the product; OAS's API is one of three interfaces. |
| MCP server (AI integration) | Yes: an npm CLI (orats mcp add) wrapping 26 endpoints across 4 tiers, supporting Claude Code and Codex, plus Otto, a natural-language agent over 95 platform tools that runs on Anthropic Claude | Yes (32 tools, native Claude / ChatGPT / Perplexity / Grok) | Both ship MCP servers. ORATS's wraps its data endpoints and pairs with Otto over its platform tools; OAS's 32 tools expose chains, surfaces, Greek/GEX history, screeners, and saved-run recall rather than on-demand multi-model pricing (that path is REST API and Python SDK). |
| Web app for end users | Yes: Trading Tools is a standalone $99/month web app with 10+ named tools | Yes (full SaaS platform with per-ticker analytics, charts, dashboards) | Corrected 2026-08: ORATS sells Trading Tools as a full retail trading application, not a thin front-end over a data feed. Both are primary product surfaces. |
| Free tier | No (paid-only) | Yes (Black-Scholes pricing, all 17 Greeks, end-of-day analysis on every ticker) | ORATS is institutional pricing across all tiers; OAS's free tier targets retail evaluation. |
| Methodology transparency | Published for the data products | Published for everything | ORATS documents its data methodology; OAS documents data sources AND analytics methodology. |
Methodology Differences That Matter
- Analytical centre of gravity is the key difference, not product category: both companies sell data and both sell an application on top of it. ORATS builds outward from its own data products, so its analytics are expressed in terms of the SMV surface, dividend forecasts and parameterized historical studies. OAS builds outward from a calibrated multi-model pricing layer, so its analytics are expressed as divergence between models, dealer-positioning structure derived from open interest, and screens that run on the calibrated surface. Users who want the data inside their own infrastructure buy the ORATS Data API; users who want it inside an application can buy either. They serve overlapping use cases from different analytical starting points.
- IV surface methodology: ORATS uses its branded SMV smoothing (a smoothed-surface methodology that produces clean and arbitrage-free surfaces with stable parameterization). OAS uses eSSVI (extended SSVI with explicit term-structure parameterization) plus Dupire local-volatility extraction, plus calibration against 17 different pricing models. The smoothed-surface fit on the data side is comparable in quality between the platforms; the difference is what each platform exposes on top of the surface.
- Pricing-model layer: ORATS does not focus on a multi-model pricing surface - the product's differentiator is the data quality and the SMV fit. OAS's multi-model engine (Black-Scholes, Heston, SABR, Variance Gamma, Jump Diffusion variants, Local Vol, FFT, PDE, Binomial, 7 exotic models) calibrates against the surface and exposes the divergence between models, which is itself a regime-detection signal.
- AI-assistant access: both platforms ship MCP servers, so this is a difference of scope rather than presence. ORATS provides an npm CLI wrapping 26 endpoints plus Otto, its own natural-language agent over 95 platform tools; OAS provides a 32-tool MCP server with native integrations for Claude, ChatGPT, Perplexity, and Grok covering the full analytics surface. For users feeding model-implied edge into AI workflows, this is a different ergonomic class.
Pricing
As of 2026-08, ORATS publishes Data API tiers at $99/month (delayed, 20k requests), $199/month (live, 100k) and $399/month (live intraday, 1M), plus Trading Tools as a separate $99/month product. The "DataShop" brand referenced by an earlier version of this page no longer appears in their navigation and that URL 404s. The Options Backtester is included in the $99/month Trading Tools package (2,000 backtests/month), not priced separately. 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, FFT scanner, dealer-flow dashboards, AI integrations, strategy builder), and an API tier (REST + WebSocket access for programmatic consumers). The buyer profiles overlap more than the price sheet suggests: ORATS sells to institutional and quant data consumers through the Data API and to retail through Trading Tools, while OAS targets retail and prosumer end users.
When to Pick ORATS
- You're a quant researcher, prop trader, or hedge fund analyst with engineering capacity to integrate a data feed into your own analytics infrastructure.
- You need institutional-grade historical depth with consistent methodology for serious backtesting where data-quality consistency materially affects results.
- Dividend forecast accuracy is operationally important for your strategy (e.g., index dividend pricing, ex-div option flows).
- You want SMV-smoothed surfaces specifically (ORATS's branded methodology) rather than multi-model alternatives.
- You're building a custom analytics layer on top of cleaned chain data and want full control over the analytics methodology.
- You want ORATS's own application rather than its feed: Trading Tools bundles the Option and Stock Scanners, Trade Builder, the Options Backtester, Strategy Optimizer, Profit Attribution, order routing and Otto at $99/month.
When to Pick Options Analysis Suite
- You want dealer-positioning analytics (GEX, DEX, vanna, charm), an FFT mispricing scanner and a multi-model regime detector. Those three are OAS-only; on screeners, strategy building and backtesting both platforms ship a product, so those are not the deciding factor.
- You want the analytics expressed as model divergence and calibrated fair value rather than as smoothed-surface statistics, and you would otherwise be building that layer yourself on top of a feed.
- You want multi-model pricing (Heston, SABR, Variance Gamma, Jump Diffusion, etc.) and model-divergence views, not just SVI surface fits.
- AI-assistant access via MCP is part of your workflow (Claude, ChatGPT, Perplexity, Grok all integrate natively).
- A free tier with all 17 Greeks and end-of-day chain analysis is the right starting point before evaluating paid tiers.
- Published methodology covering analytics AND data sourcing matters for your research process.
When Either Works
- For end-of-day chain accuracy and IV surface fitting on liquid US equities, both platforms operate on institutional-grade OPRA-derived data of comparable depth.
- For backtester-style historical research, both platforms have a backtester, with ORATS more research-oriented and OAS more strategy-oriented.
- For programmatic access to chain data, both platforms expose comparable REST APIs.
Alternatives to ORATS
Traders looking for alternatives to ORATS typically fall into two groups. Engineers and quant researchers with infrastructure to consume a data feed often evaluate other institutional vendors (CBOE LiveVol, IvyDB, Polygon). Users who want the analytics delivered as an application weigh ORATS's Trading Tools against other end-user platforms. Options Analysis Suite is in the second group: it consumes institutional-grade end-of-day chain data and adds a calibrated multi-model pricing engine, dealer-positioning analytics, screeners, strategy builder, Python SDK, and MCP server.
Other alternatives to ORATS in the options data and analytics space include the dealer-flow specialists (SpotGamma, MenthorQ) for users primarily focused on positioning, and Market Chameleon for per-ticker IV and earnings-move research.
