Security Status Request (MsgType = e, FIXML = SecStatReq)

The Security Status Request (e) message provides for the ability to request the status of a security. One or more Security Status (f) messages are returned as a result of a Security Status Request (e) message.

The Security Status Request (e) message contains a SubscriptionRequestType (263) field. This tells the counter party what type of request is being made:

0: indicates that the requestor only wants a snapshot or the current status.
1: indicates that the requestor wants a snapshot (the current status) plus updates as the status changes. This is similar to subscribing for information and can be implemented in applications as a subscription mechanism.
2: indicates that the requestor wishes to cancel any pending snapshots or updates - in essence making this an unsubscribe operation.
