First Order Greeks

- Returns the data for all contracts that share the same provided symbol and expiration. - Calculated using the option and underlying midpoint price. If an interval size is specified (*highly recommended*), the option quote used in the calculation follows the same rules as the [quote](/operations/option_history_quote.html) endpoint. - The underlying price represents whatever the last underlying price was at the ``timestamp`` field. You can read more about how Theta Data calculates greeks [here](/Articles/Data-And-Requests/Option-Greeks.html). - Multi-day requests are limited to 1 month of data.
