iLink Order Cancel-Replace and In-Flight Mitigation

In-flight mitigation (IFM) is an optional feature on CME Globex that allows client systems submitting cancel/replace messages to prevent overfilling in the event that the original order is filled while the cancel/replace message is "in-flight" during processing.

https://www.cmegroup.com/confluence/display/EPICSANDBOX/iLink+Order+Cancel-Replace+and+In-Flight+Mitigation

This feature is currently disabled by default via Whisperer. If clients wish to utilise this feature, they should ensure that their MultilegOrderCancelReplaceRequest message includes:

  • BodyPassthruKey   = "OFMOverride"

  • BodyPassthruValue = "Y"

Refer to Passthru Fields above for details.
