ORATS vs FlashAlpha: Historical Options Data & Backtesting (2026)

Disclosure: FlashAlpha publishes this comparison. Official sources were checked on September 8, 2026. We have not run a controlled accuracy or strategy-return benchmark between these services.

ORATS Historical Options Data and API Pricing

The ORATS Data API page lists these individual plans:

That page dates end-of-day history to 2007 and one-minute data history to August 2020. It separately dates the intraday backtesting engine's bars to October 2020. These describe different products; check the endpoint required for your study. Live access requires signed data agreements.

ORATS also lists Backtest Finder at an additional $99/month and Intraday Backtester at an additional $299/month. All-In includes the Tools APIs. The page states that API free trials are unavailable and points to sample data for evaluation.

Backtesting API vs Historical Analytics Replay

FlashAlpha's Historical API serves supported historical analytics routes on Alpha. It can supply research inputs, but a GEX response is not a completed strategy backtest. You still need a rule, execution prices, costs and a validation period.

FlashAlpha's historical methodology says exposure analytics are recomputed through the current engine. They are not archived copies of the model output originally published on that date. Its documented SPY history starts January 3, 2017; other symbols have different start dates. Record the retrieval date and available engine or methodology version. Check per-symbol coverage and gaps, and distinguish minute-level quotes and Greeks from daily inputs and unavailable fields.

ORATS should not be reduced to raw data without calculations: its current offering includes calculated indicators and backtesting APIs. Compare the response your study needs rather than an outdated product category.

Price the Complete Research Job

Using the listed components, ORATS Delayed Data plus Backtest Finder totals $298/month; Live Data plus Intraday Backtester totals $598/month. These are component sums, not custom quotes. Confirm the combined entitlements before buying.

For FlashAlpha historical replay, budget for Alpha rather than Free or Basic. Check current pricing alongside the historical route list. A live single-expiry test cannot demonstrate historical entitlement or historical data quality.

Estimate request volume for the real symbol list, dates and parameter combinations. A single example does not establish that a monthly allowance will cover the study.

A Historical-Data Evaluation You Can Reproduce

1. Specify one question. For example: did a rule based on yesterday's exposure state change next-session returns after costs?
2. Fix observation time. Record timezone and distinguish near-close observations, closing values and intraday snapshots.
3. Check availability at that time. Later-known open interest, revised fields or future prices can introduce look-ahead bias.
4. Inspect edge cases. Include expiration, a corporate action and a missing-data session. Do not fill gaps with future values.
5. Separate model output from fills. Specify execution prices, spreads and commissions independently.

ORATS documents token placement and formats in its authentication guide. Keep credentials out of published notebooks and screenshots.

FlashAlpha monthly billing is $0 for Free, $79 for Basic, $299 for Growth and $1,499 for Alpha, as listed on the pricing page on September 8, 2026. Match the capability to the plan before comparing costs.

FlashAlpha standard plans cover personal or single-team internal use. The published usage terms exclude redistribution, embedding, white-label and publisher licensing; API access does not grant permission to resell or publicly embed the data.

Which One Should You Evaluate First?

Start with ORATS when its contract history or backtesting tools answer the brief. Start with FlashAlpha when you need the exposure outputs available through its historical routes. If the study needs both simulation and exposure features, evaluate a combined pipeline.
