Parameters
The date to fetch data for. If present, this overrides start_date and end_date.
The stock or index symbol, or underlying symbol for options.
The expiration of the contract in YYYY-MM-DD or YYYYMMDD format, or * for all expirations. * is limited to one day at a time and an interval of at least 1m; tick and sub-minute intervals are rejected.
The strike price of the contract in dollars (ie 100.00 for $100.00), or * for all strikes.
The right (call or put) of the contract.
The start time (inclusive) in the specified day (format 24-hour HH:MM:SS.SSS).
The end time (inclusive) in the specified day (format 24-hour HH:MM:SS.SSS).
The size of the time interval must be one of the available options listed below. Intervals less than 1m are available only for single-day requests.
The annualized continuous dividend yield used in Greeks calculations, as a decimal (e.g. 0.0042 for a 0.42% yield). To pass a dollar amount instead, use annual_dividend_amount. Must be non-negative.
The interest rate type to be used in a Greeks calculation.
The interest rate, as a percent, to be used in a Greeks calculation.
Used to adjust Greeks calculation methodology. "1" uses a fixed .15 DTE for 0DTE; "latest" uses real TTE (down to a minimum of 1 hour)
Limits the number of contracts returned relative to the underlying's spot price. For a specified value 'n', this returns 'n' strikes above and 'n' strikes below the spot price, plus one at-the-money (ATM) strike (where spot price = strike price), if available. This results in a maximum of 2n + 1 strikes.
The start date (inclusive).
The end date (inclusive).
The annual dividend per share in dollars used in Greeks calculations (e.g. 0.96 for $0.96 per year). It is converted to a yield for each tick by dividing by the underlying price used for that tick. Must be non-negative, and cannot be combined with a non-zero annual_dividend.
