The Security Status <f> message provides for the ability to report changes in status to a security. The Security Status <f> message contains fields to indicate trading status, corporate actions, financial status of the company. The Security Status <f> message is used by one trading entity (for instance an exchange) to report changes in the state of a security.
It is expected that the Security Status <f> message that is sent as a response should indicate what type of request is being provided. If the message is being generated
as a result of a RequestType <263> ='1', then the response should have a RequestType <263>='1' to permit the requestor to determine why the
message was sent.
