This endpoint enables users to exercise a held option contract, converting it into the underlying asset based on the specified terms.
All available held shares of this option contract will be exercised.
By default, Alpaca will automatically exercise in-the-money (ITM) contracts at expiry.
Exercise requests will be processed immediately once received. Exercise requests submitted outside market hours will be rejected.
To cancel an exercise request or to submit a Do-not-exercise (DNE) instruction, please contact our support team.
