Order Cancel Replace Request

Amending Working Orders

The Order Cancel-Replace Request message (MsgType=G) is used by the T4 FIX API to electronically amend (i.e. revise) the replaceable fields of working orders. This message is used for all CTS strategy types including outright futures, futures options, spreads and multileg strategies.

The instrument (for which the replace applies) is identified with the following tags: Tag 48 (SecurityID), Tag 55 (Symbol) Tag 207 (SecurityExchange) and Tag 167 (SecurityType). Options orders must also include the Strike Price (Tag 202) and the PutOrCall indicator (Tag 201).

In addition to full market specification, all cancel-replaces must be uniquely identified with a verbose (# characters >= 12 and <= 20) Client Order Id (Tag 11). The subscribed account (for which the replace order is submitted) must also be entered.

Replaceable Fields

The fields that can be replaced are:
TagTag NumberComments
Order Quantity38For all Orders
Price44For Limits, Stop Limits and Market-If-Touched
Stop Price99For Stops and Stop Limits
MaxShow210For Icebergs (if supported by Exchange)
Trailing Delta10100For Trailing Stops
Activation Value10103For Activation Orders

Identifying the Order to be Replaced

Working orders to be replaced can be identified with the working order (client-side) identifier or the (T4 FIX API generated) order identifier. For the replace message, the OrigClOrdId (Tag 41) and the OrderId (Tag 37) are the corresponding fields. Working orders that have experienced previous rejections can subsequently be replaced with OrderId (Tag 37) or by using the ClOrdId (Tag 11) of the previous rejection.

Orders submitted outside the T4 FIX API (e.g. with the CTS T4 Front-End and/or custom T4 API application) can only be replaced with OrderId (Tag 37). In this case, as OrigOrdClId is undetermined but is a required tag for the replace order, the OrigOrdClId (Tag 41) is set to the value of the OrderId (Tag 37). To cover all scenarios, it is recommended that both OrigClOrdId (Tag 41) and OrderId (Tag 37) be specified for all cancel-replaces.

Activating Queued Orders

For the specific case of Queue Orders, the cancel replace message is used to activate a (held/suspended) queued order. In addition to specifying the correct market and its target order id, the Activation Value (Tag 10102) must be set to -1.

Important Considerations

Note that malformed replace orders (including missing required tags, empty tags, invalid tag value range, etc.) will be rejected with a FIX Session Reject message. Application level rejections are manifested with Cancel Reject messages.

Please note that all order routing including the submission of cancel-replace orders must be preceded by a successful subscription to the account the cancel-replace is submitted for. Please refer to the Collateral Inquiry message on how to subscribe to customer accounts.

Contigent (multiple-component) orders like OCO's and AutoOCO's can only be replaced one component at a time. The individual components are identified by their OrigClOrdID (Tag 41) and/or (Tag 37) OrderID as explained above.
