# Execution Report

> Order acknowledgements, fills, amends, cancels and status answers

<div className="api-banner">
  <span className="api-protocol fix">FIX</span>
  <span className="api-detail">session: trading</span>
  <span className="api-tag">35=8</span>
</div>

Reports every state change on an order once the engine has accepted it. ExecType says what happened — new, replaced, cancelled, expired, traded, restated, or an answer to a status request — and OrdStatus says what state the order is now in. Fills carry LastPx, LastQty, the running CumQty and AvgPx, the trade identifier, and the maker/taker flag in LastLiquidityInd.

**Direction:** Kraken → client

***

<ResponseField name="header" type="" required>35=`8`</ResponseField>

<ResponseField name="37 - OrderID" type="string">
  Exchange-assigned order identifier generated by Kraken; the value to quote back on cancels, amends and status requests.

  **Format:** Assigned by Kraken; quote it back on cancels, amends and status requests.
</ResponseField>

<ResponseField name="11 - ClOrdID" type="string" required>
  Client-assigned order identifier, as sent by the client. On US Perps it is a positive integer of at most 19 digits.

  **Format:** Positive integer, up to 19 digits, e.g. a microsecond timestamp.
</ResponseField>

<ResponseField name="41 - OrigClOrdID" type="string">
  ClOrdID of the previous action on the order. Sent on cancel and amend reports.

  <span className="field-attr">Required:</span> Conditional
</ResponseField>

<ResponseField name="17 - ExecID" type="string" required>
  Unique identifier of this execution report. Treat it as opaque: do not parse it or derive it from ClOrdID. On US Perps the New (`150=0`) acknowledgement uses a ClOrdID-based form, reports driven by the engine carry an engine-generated identifier, and an Order Status answer (`150=I`) repeats the ExecID of the cached report.
</ResponseField>

<Note>
  **ExecID: venue differences**

  | | US Perps | Spot | Futures |
  | :- | :- | :- | :- |
  | Format | Opaque; three forms, see above | Base32 of a ClOrdID-derived value plus a timestamp | Same as Spot |
</Note>

<ResponseField name="150 - ExecType" type="char" required>
  Nature of the event this execution report describes.

  **Possible values:**

  * `0` : New - the order is live in the engine.
  * `4` : Canceled - the order was cancelled.
  * `5` : Replace - the amend was applied.
  * `8` : Rejected - the matching engine refused an order it had already acknowledged, for example a post-only order that would cross, a fill-or-kill order that cannot be filled in full or an order stopped by market price protection. The report carries OrdRejReason (103) and Text (58). A request refused before it is acknowledged (an unsupported feature, an invalid field, a risk limit) arrives as a BusinessMessageReject (35=j) instead. Engine limit checks (quantity cap, price bounds and bands) map to OrdRejReason `3`, so they may arrive as `150=8` rather than `35=j`; this is to be confirmed in UAT.
  * `C` : Expired - the order reached its expiry.
  * `D` : Restated - the engine changed the order itself, for example by re-displaying an iceberg slice.
  * `F` : Trade - the order got a fill. LastPx/LastQty carry that fill.
  * `I` : Order Status - this report answers an OrderStatusRequest rather than reporting an event.
</ResponseField>

<ResponseField name="39 - OrdStatus" type="char" required>
  Current state of the order.

  **Possible values:**

  * `0` : New - live, nothing filled.
  * `1` : Partially filled - live with fills against it.
  * `2` : Filled - fully filled and closed.
  * `4` : Canceled - cancelled and closed.
  * `8` : Rejected - the matching engine refused the order after acknowledging it. See OrdRejReason (103) and Text (58) for the reason.
  * `C` : Expired - expired and closed.
</ResponseField>

<ResponseField name="103 - OrdRejReason" type="integer">
  Code identifying the reason why an order was rejected by the matching engine. Present only on Execution Reports with ExecType (150) = 8 and OrdStatus (39) = 8. The gateway maps only the values below; match-time rejects use `3`, `11` and `99`. Which engine rejections reach `150=8` is decided by the engine.

  **Possible values:**

  * `1` : Unknown symbol.
  * `2` : Exchange closed.
  * `3` : Order exceeds a limit (quantity cap, price bounds and bands).
  * `5` : Unknown order.
  * `6` : Duplicate order.
  * `11` : Unsupported order characteristic.
  * `13` : Incorrect quantity.
  * `99` : Other.

  The other FIX 4.4 values are not sent.
