As of FIX 4.4 we have tag SecuritySubType (762) to further qualify the type of security. It is tough to keep the entire text of the spec up to date and comments pointing out such inconsistencies are welcome. The CFI Code has the disadvantage that it needs to be parsed. Processing is easier (and probably faster) if one has explicit fields. For that reason PutOrCall was reintroduced. For FIX versions below 4.4, CFICode (461) is probably the best way to go (only if SecurityType is insuffcient) unless you can pull in tags from higher versions. With FIX 4.4 and above I would opt for SecurityType (167) and SecuritySubType (762). > There is a relevant discussion on this at > http://www.fixprotocol.org/discuss/read/19f5aae5 > > However, one issue that does not seem to be addressed is how do you > specify that the underlying of the derivative is an interest rate rather > than anything else? > > CFICode(461) addresses this issue (but it was only introduced in > FIX4.3).
