Definition of a Security

The Security Definition message (Tag 35=d) is used to define the characteristics of exchanges, contracts and specific instruments (markets). The T4 FIX API returns this message as a result of queries performed with the Security Definition Request message.

The Security definition message includes a complete description of securities by providing Exchange identifier, Contract identifier, Market identifier, pricing, minimum trading volumes, minimum price amount (including Variable Tick Tables), quantity leg ratios, buy/sell sides, put/call type, strikes, etc. This message also enumerates lists of exchanges, contracts within an exchange and markets for a specific contract.
