Create order

post

https://api.clearstreet.io/studio/v2/accounts/{account_id}/event-contracts/orders

Creates a new event contract order for the account. The order is processed asynchronously; a successful response indicates the order was received and is pending further processing, not that it has been accepted by the venue. Use the list orders and list trades endpoints, as well as the event contracts WebSocket to observe order lifecycle and fills.
