Live Derived Data API

View as Markdown

Get live options data calculated in real-time with less than 10 seconds of market delay. These endpoints are the same as the Live Data API endpoints, except they do not include OPRA data, which means the bid-ask price, size, and volume are null.

ORATS does not provide stock prices for US equities, ETFs or indexes. The underlying values in our data, live and historical, are derived from option prices using put-call parity and are for internal use only. They are reference prices, not a replacement for real stock prices. For real stock prices, use a different provider.
