Instrument Deletion and SecurityListRequest

Imported from previous forum

Hi All,

In the SecurityListRequest message (‘x’) you can request updates by setting the value of the SubscriptionRequestType (263) to 1. Now if instruments are added during the session that match the client’s request we can send along a SecurityList message (‘y’) with the new instrument. But what do I send if an instrument is deleted from the market during a session?

The update message is SecurityListUpdateReport (“BK”) which has a field SecurityUpdateAction (980) with values Add/Modify/Delete. This can be used for incremental updates including deletions.
