## Submit Position Instructions

`PositionSubmitPositionInstructionsResponse v1().positions().submitPositionInstructions(PositionSubmitPositionInstructionsParamsparams, RequestOptionsrequestOptions = RequestOptions.none())`

**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

- `PositionSubmitPositionInstructionsParams params`

  - `Optional<Long> accountId`

  - `List<Instruction> instructions`

    - `PositionInstructionType instructionType`

      The action to take.

      - `EXERCISE("EXERCISE")`

      - `DO_NOT_EXERCISE("DO_NOT_EXERCISE")`

      - `CONTRARY_EXERCISE("CONTRARY_EXERCISE")`

    - `String instrumentId`

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

    - `String quantity`

      Number of contracts to include in the instruction.

    - `Optional<String> instructionId`

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

### Returns

- `class PositionSubmitPositionInstructionsResponse:`

  - `List<PositionInstruction> data`

    - `String id`

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

    - `long accountId`

      Account the instruction belongs to.

    - `String instructionId`

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

    - `PositionInstructionType instructionType`

      The action this instruction requests.

      - `EXERCISE("EXERCISE")`

      - `DO_NOT_EXERCISE("DO_NOT_EXERCISE")`

      - `CONTRARY_EXERCISE("CONTRARY_EXERCISE")`

    - `String instrumentId`

      Identifier of the options contract this instruction acts on.

    - `String quantity`

      Number of contracts included in the instruction.

    - `PositionInstructionStatus status`

      Current lifecycle status.

      - `SENT("SENT")`

      - `ACCEPTED("ACCEPTED")`

      - `REJECTED("REJECTED")`

      - `ENGINE_REJECTED("ENGINE_REJECTED")`

      - `CANCEL_REQUESTED("CANCEL_REQUESTED")`

      - `CANCELLED("CANCELLED")`

      - `CANCEL_FAILED("CANCEL_FAILED")`

      - `UNKNOWN("UNKNOWN")`

    - `String symbol`

      Options symbol (OSI) for display.

    - `Optional<String> acceptedQuantity`

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

    - `Optional<LocalDateTime> createdAt`

      When the instruction was first accepted by the service.

    - `Optional<String> rejectionReason`

      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.

    - `Optional<LocalDateTime> updatedAt`

      When the instruction's lifecycle state last changed.
