Schema

datarequiredobject (PlacedOrderResponse)
The response returned when placing, editing, or dry-running an order or complex order. Contains the resulting `order` (or `complex-order`), the `buying-power-effect`, the `fee-calculation`, and any `warnings`, `errors`, or `notes` produced by the preflight checks.
- buying-power-effectobject{13 fields}
  Details of the order's impact on the account's buying power, including the change in buying power and its direction. A JSON object (upstream types this field as a string; attested responses return this object, with decimal values serialized as JSON strings).
- closing-fee-calculationstring
  An estimate of the fees to expect when later closing the position this order would open. Provided as a convenience; not applied to this order.
- complex-orderobject{10 fields}
- errorsarray<object>{3 fields}
  Preflight errors explaining why the order failed validation, each with a `code`, `message`, and `preflight-id`.
- fee-calculationobject{10 fields}
  An estimate of the fees the order would incur if filled, broken into regulatory, clearing, commission, and other categories and totaled at the end. A JSON object (upstream types this field as a string; attested responses return this object, with decimal values serialized as JSON strings).
- notesarray<object>{4 fields}
  Informational notes about the order, each optionally including a `url` for more detail.
- orderobject{42 fields}
- warningsarray<object>{3 fields}
  Informational warnings produced by a dry-run or submission. A warning may indicate the order would be rejected if routed, or that the market is closed.
