</div>

To submit a new order, the client needs to send a NewOrderSingle message. All orders are submitted from the client's perspective to Kraken exchange to place bid/offer on the Kraken Order book.
A range of order types, Time-In-Force (TIF) and order flags can be specified by the parameters below.

The supported order types are:

* `market`: The full order quantity executes immediately at the best available price in the order book.
* `limit`: The full order quantity is placed immediately with a limit price restriction to only trade at this price or better.
* `stop-loss`: A market order is triggered when the reference price reaches the stop price (from an unfavourable direction).
* `stop-loss-limit`: A limit order is triggered when the reference price reaches the stop price (from an unfavourable direction).
* `take-profit`: A market order is triggered when the reference price reaches the stop price (from a favourable direction).
* `take-profit-limit`: A limit order is triggered when the reference price reaches the stop price (from a favourable direction).
* `trailing-stop`: A market order is triggered when the market reverts a specified distance from the peak price.
* `trailing-stop-limit`: A limit order is triggered when the market reverts a specified distance from the peak price.

<ResponseField name="header" type="" required>35=`D`</ResponseField>

<ResponseField name="11 - ClOrdID" type="string" required>
  Unique identifier of the order. The ID can be one of the following formats:

  * **Ever-Increasing Positive Numbers**: Ever-increasing positive numbers, such as microsecond timestamps, to ensure the uniqueness and sequential nature of the identifiers. (Spot only)
    **Example**: Using the current microsecond timestamp as the ClOrdID, such as `1623448294234000` (Max 18 characters)
  * **Timestamp-First v4 UUIDs** (required for Futures, supported for Spot): A COMB UUID where the first 48 bits (first two UUID fields) encode the current timestamp in **10-microsecond units** since the Unix epoch. Example: `a17d49af-1186-4984-bd10-29b8f232ee4d`, where `a17d49af-1186` encodes the timestamp `177559467882990` (= 10-μs units for a given moment).

<Note>
  **Order Validation** — Kraken will validate each order it receives by checking that the user sent all the required FIX fields for the order.

  * FIX field level validation will result in [session level reject](/exchange/api-reference/unified-fix/reject-session).
  * Business rule validation failures will result in rejection in the form of a [business level reject](/exchange/api-reference/unified-fix/reject-business).
  * Once the order is accepted and Acked, any further business rule validations will result in an [execution report](/exchange/api-reference/unified-fix/er) with an unsolicited cancel status.
