Third Order Greeks (v3) ​

REQUIRED

The v3 Theta Terminal must be running to access data.

  • Retrieve a real-time last third order greeks calculation for all option contracts that lie on a provided expiration.
  • You might need to change the default expiration date to a different date if it is past the current date. Some quotes are omitted in the example to reduce the space of the sample output.
  • Make expiration * if you want to get the snapshot for every expiration chain for the underlying.

This endpoint will return no data if the market was closed for the day. Theta Data resets the snapshot cache at midnight ET every night.
