## Submit Position Instructions

`client.V1.Positions.SubmitPositionInstructions(ctx, accountID, body) (*V1PositionSubmitPositionInstructionsResponse, error)`

**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.

### Parameters

- `accountID int64`

- `body V1PositionSubmitPositionInstructionsParams`

  - `Instructions param.Field[[]V1PositionSubmitPositionInstructionsParamsInstruction]`

    - `InstructionType PositionInstructionType`

      The action to take.

      - `const PositionInstructionTypeExercise PositionInstructionType = "EXERCISE"`

      - `const PositionInstructionTypeDoNotExercise PositionInstructionType = "DO_NOT_EXERCISE"`

      - `const PositionInstructionTypeContraryExercise PositionInstructionType = "CONTRARY_EXERCISE"`

    - `InstrumentID string`

      Identifier of the options contract to act on. Unknown ids return 404.

    - `Quantity string`

      Number of contracts to include in the instruction.

    - `InstructionID string`

      Caller-supplied idempotency key. Echoed on the response. The server
      generates a unique id when omitted.

### Returns

- `type V1PositionSubmitPositionInstructionsResponse struct{…}`

  - `Data PositionInstructionList`

    - `ID string`

      Server-assigned id. Used as the path parameter on cancel.

    - `AccountID int64`

      Account the instruction belongs to.

    - `InstructionID string`

      Caller-supplied idempotency key echoed from the submit request; the
      server-assigned fallback when none was supplied.

    - `InstructionType PositionInstructionType`

      The action this instruction requests.

      - `const PositionInstructionTypeExercise PositionInstructionType = "EXERCISE"`

      - `const PositionInstructionTypeDoNotExercise PositionInstructionType = "DO_NOT_EXERCISE"`

      - `const PositionInstructionTypeContraryExercise PositionInstructionType = "CONTRARY_EXERCISE"`

    - `InstrumentID string`

      Identifier of the options contract this instruction acts on.

    - `Quantity string`

      Number of contracts included in the instruction.

    - `Status PositionInstructionStatus`

      Current lifecycle status.

      - `const PositionInstructionStatusSent PositionInstructionStatus = "SENT"`

      - `const PositionInstructionStatusAccepted PositionInstructionStatus = "ACCEPTED"`

      - `const PositionInstructionStatusRejected PositionInstructionStatus = "REJECTED"`

      - `const PositionInstructionStatusEngineRejected PositionInstructionStatus = "ENGINE_REJECTED"`

      - `const PositionInstructionStatusCancelRequested PositionInstructionStatus = "CANCEL_REQUESTED"`

      - `const PositionInstructionStatusCancelled PositionInstructionStatus = "CANCELLED"`

      - `const PositionInstructionStatusCancelFailed PositionInstructionStatus = "CANCEL_FAILED"`

      - `const PositionInstructionStatusUnknown PositionInstructionStatus = "UNKNOWN"`

    - `Symbol string`

      Options symbol (OSI) for display.

    - `AcceptedQuantity string`

      Number of contracts accepted by the clearing venue. Populated once
      the instruction reaches `ACCEPTED`.

    - `CreatedAt Time`

      When the instruction was first accepted by the service.

    - `RejectionReason string`

      Human-readable explanation populated on any non-success terminal
      status — `REJECTED`, `ENGINE_REJECTED`, or `CANCEL_FAILED`. On a
      `207 Multi-Status` batch submit the top-level `error` field
      summarizes the batch; per-row detail continues to live here.

    - `UpdatedAt Time`

      When the instruction's lifecycle state last changed.
