The Security Definition Request message is used for the following:

  1. Request a specific Security to be traded with the second party. The request security can be defined as a complex security made up of one or more underlying securities.
  2. Request a list of the Security Types that can be traded with the second party.
  3. Request a list of Securities that can be traded with the second party. This request can optionally be qualified with Symbol, TradingSessionID, SecurityExchange, and Security Type.
