stock

Option Chains

Returns all option symbols for the given ticker that were present at the given day.

If no date is given, returns data for the current/last market day.

You can use the following regex to extract underlying ticker, option type, expiry & strike: ^(?<symbol>[\w]*)(?<expiry>(\d{2})(\d{2})(\d{2}))(?<type>[PC])(?<strike>\d{8})$

Keep in mind that the strike needs to be divided by 1,000.

With greeks=true, the response is paginated. Rows are sorted by expires, then strike, then option_symbol, all ascending. limit sets the page size and page selects the page, starting at 0. Without greeks=true, the response contains every option symbol and limit and page have no effect.

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

ticker

string

required

A single ticker

date

string

A trading date in the format of YYYY-MM-DD. This is optional and by default the last trading date.

Example:

"2024-01-18T00:00:00.000Z"

greeks

boolean

When true, return an enriched row per contract (strike, expiry, type, NBBO, IV, OI, volume, delta, gamma, theta, vega, rho, last_tape_time) instead of the default array of option-symbol strings. Enriched rows are paginated with limit and page.

limit

integer

default:500

How many enriched rows to return when greeks=true. Max: 500. Min: 1. Returns up to 500 when omitted. How many items to return. Max: 500. Min: 1. Returns up to 500 when omitted.

Required range: 1 <= x <= 500

Example:

10

page

integer

Page number of enriched rows when greeks=true. Starts on page 0. Page number (use with limit). Starts on page 0.

Example:

1

Response

Option chains response

All option chains for a given ticker. By default data is an array of option-symbol strings.

Pass greeks=true to instead get an enriched object per contract with strike, expiry, type, NBBO (nbbo_bid/nbbo_ask), implied_volatility, open_interest, volume, delta, gamma, theta, vega, rho and last_tape_time. Enriched rows are sorted by expires, strike and option_symbol and returned in pages of up to 500. Use limit and page to read the rest of the chain.

Example enriched row (greeks=true):

{
  "option_symbol": "AAPL231020C00185000",
  "strike": 185,
  "expires": "2023-10-20",
  "option_type": "call",
  "nbbo_bid": 4.35,
  "nbbo_ask": 4.45,
  "implied_volatility": 0.2612,
  "open_interest": 1200,
  "volume": 842,
