OptionRATS

ORATS (Options Research & Technology Services) is committed to providing options traders with the most sophisticated data and tools. Since 2001, our products have served thousands of retail traders, hedge funds, and institutional clients. Our products are centered around our advanced, proprietary volatility analysis that we use to produce best-of-breed implied, forecasted, and historical volatilities.

Our trading tools are designed to help options traders make smarter decisions through a suite of backtesting, scanning, execution, and risk analysis web tools.

Our APIs are REST-based and designed to be powerful, quick, and easy to use. We offer live, delayed, and historical API endpoints to query both end-of-day options data (back to 2007) and intraday one-minute options data (back to 2020).

Our historical data files are available for download via FTP or AWS S3, and include accurate Greeks, theoretical values, and volatility data for over 5,000 US equity option symbols.
