Do Not Exercise an Options Position

This endpoint enables users to submit a do-not-exercise (DNE) instruction for a held option contract, preventing automatic exercise at expiry. By default, Alpaca will automatically exercise in-the-money (ITM) contracts at expiry. This endpoint allows users to override that behavior. DNE requests will be processed immediately once received. DNE requests submitted between market close and midnight will be rejected to avoid any confusion about when the instruction will take effect. To cancel a DNE request or to submit an exercise instruction, please contact our support team.
