## 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.

### Parameters

- `account_id: int`

- `instructions: Iterable[Instruction]`

  - `instruction_type: PositionInstructionType`

    The action to take.

    - `"EXERCISE"`

    - `"DO_NOT_EXERCISE"`

    - `"CONTRARY_EXERCISE"`

  - `instrument_id: str`

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

  - `quantity: str`

    Number of contracts to include in the instruction.

  - `instruction_id: Optional[str]`

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

### Returns

- `class PositionSubmitPositionInstructionsResponse: …`

  - `data: PositionInstructionList`

    - `id: str`

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

    - `account_id: int`

      Account the instruction belongs to.

    - `instruction_id: str`

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

    - `instruction_type: PositionInstructionType`

      The action this instruction requests.

      - `"EXERCISE"`

      - `"DO_NOT_EXERCISE"`

      - `"CONTRARY_EXERCISE"`

    - `instrument_id: str`

      Identifier of the options contract this instruction acts on.

    - `quantity: str`

      Number of contracts included in the instruction.

    - `status: PositionInstructionStatus`

      Current lifecycle status.

      - `"SENT"`

      - `"ACCEPTED"`

      - `"REJECTED"`

      - `"ENGINE_REJECTED"`

      - `"CANCEL_REQUESTED"`

      - `"CANCELLED"`

      - `"CANCEL_FAILED"`

      - `"UNKNOWN"`

    - `symbol: str`

      Options symbol (OSI) for display.

    - `accepted_quantity: Optional[str]`

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

    - `created_at: Optional[datetime]`

      When the instruction was first accepted by the service.

    - `rejection_reason: Optional[str]`

      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.

    - `updated_at: Optional[datetime]`

      When the instruction's lifecycle state last changed.

### Example

```python
from clear_street import ClearStreet

client = ClearStreet(
    api_key="My API Key",
)
response = client.v1.positions.submit_position_instructions(
    account_id=0,
    instructions=[{
        "instruction_type": "EXERCISE",
        "instrument_id": "0195f6d0-a1b2-7c3d-8e4f-5a6b7c8d9e02",
        "quantity": "1",
    }],
)
print(response)
```
