Order Cancel Request

Request the cancellation of a single order or multiple orders (Mass Cancel) on the FIX session. Note that Order Cancel Requests do not apply to open orders across multiple sessions unless submitted on a Purge Port.

The system limits the rate at which identical Mass Cancel and Purge Orders requests can be submitted to the system. Requests are restricted to twenty (20) messages per second per port.

An identical Mass Cancel message is defined as a message having all of the same CustomGroupID, Symbol, Clearing Firm, Instrument Type Filter and GTC Order Filter field values, as a previously received message.

TagField NameReq’dDescription
35Standard Message HeaderYMsgType=‘F’
97PossResendN
  • Y=Indicates an application level unsolicited resend. If ClOrdID has not yet been seen, the cancel is treated as normal. If ClOrdID already exists, the resent cancel is ignored.
  • N=(default) Indicates a new cancel.
11ClOrdIDY
  • Unique cancel ID chosen by TPH. 20 characters or less. Characters in ASCII range 33-126 are allowed, except for comma, semicolon, and pipe.
  • A leading tilde (~) cannot be sent on any ClOrdId and will result in a reject. These are reserved for internal use by CFE and could be received as a result of a system-generated ClOrdId.
  • Duplicate order ClOrdIDs will be rejected (or ignored if PossResend= Y).
41OrigClOrdIDNClOrdID of the order to cancel. If the referenced order has undergone multiple changes, this will be the ClOrdID of the most recent accepted change.
37OrderIdN
  • OrderId of the order to cancel as supplied by CFE on the associated order acknowledgement. The OrderId is constant even in the event of multiple changes to a single order.
  • If both the OrigClOrdID and OrderId are supplied and MassCancelInst is not, OrderId is used.
60TransactTimeYTime cancel initiated/released. Required by FIX 4.2.
55SymbolNFutures product will be used when specifying a Mass Cancel operation by product level.
7700MassCancelInstN
  • Used to perform Mass Cancel operation rather than single order cancel. If MassCancelInst is provided, OrderId, OrigClOrdId, MaturityMonth, and MaturityDay will be ignored.
  • At least one character must be provided (Clearing Firm Filter). Contiguous characters must be specified up to total length. Truncated/unspecified characters will default to values indicated (Default) below.
  • 1st Character : Clearing Firm Filter
  • A=No filtering by EFID is performed.
  • F=All orders that were sent under the EFID specified in OnBehalfOfCompId (115) will be cancelled.
  • 2nd Character : Acknowledgement Style
  • M=(Default) Individual Execution Reports are sent for each cancelled order.
  • S=Single Execution Report sent once all cancels have been processed. Single Execution Report will contain MassCancelId (7695) and CancelledOrderCount (7696). MassCancelId (7695) must be specified or the Order Cancel Request will be rejected.
  • B=Both individual Execution Reports and single summary Execution report. Also requires MassCancelId (7695) to be specified or the Order Cancel Request will be rejected.
  • 3rd Character : Lockout Instruction
  • N=(Default) No lockout (Effective 08/24/26, this instruction will be required for all Mass Cancel messages)
  • L=Lockout until corresponding Risk Reset received. Lockout can be used only with Clearing Firm Filter set to ‘F’, otherwise the Order Cancel Request will be rejected. Lockout will apply to all new orders and cancel/replace orders for the EFID (and Symbol (55), if specified), regardless of other filtering in the MassCancelInst. Effective 08/24/26, Mass Cancel messages with Lockout Instruction = L will be rejected.

  • S=Cancel Simple orders only

  • A self-imposed lockout can be released using RiskReset (7692) in the New Order Single message. If Symbol (55) is specified, a Product level reset is required, otherwise a Firm level reset is required to release a lockout.
