Submit Position Instructions

v1.positions.submit_position_instructions(intaccount_id, PositionSubmitPositionInstructionsParams**kwargs) -> PositionSubmitPositionInstructionsResponse
POST/v1/accounts/{account_id}/positions/instructions

Submit one or more position instructions (Exercise, Do-Not-Exercise, Contrary Exercise Advice) against the account.

Batch semantics:

  • All rows accepted → 200 OK. Every row is in data with status = SENT.
  • Partial success → 207 Multi-Status. data contains every row; rejected rows carry status = ENGINE_REJECTED (or REJECTED) and rejection_reason. The top-level error summarizes the batch failure.
  • All rows rejected → 4xx/5xx error response. The HTTP status reflects the underlying cause: 409 for duplicate instruction_id, 400 for validation failures such as DNE/CEA on a non-expiry day, 503 if the clearing service is unavailable. No data is returned.

Pre-flight validation (unknown instrument_id, unencodable quantity) short-circuits the whole batch with a 4xx before any row is submitted.
