Open Interest
- Retrieve the last open interest message of an option contract. - Open interest is reported around 06:30 ET every morning by OPRA and reflects the open interest at the of the previous trading day. - You might need to change the default expiration date to a different date if it is past the current date. - 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.
