Is there an established industry standard naming convention (regardless of message format) for the following data element codes?
Exchange Code
Security Ticker
Country Code
Currency Code
One example for Currency Code: USD = United States Dollar
I ask because we are going to send messages via multiple formats as our audience is technologically diversified. Thank you for your feedback.

See FIX 4.3 Volume 6’s “Appendix 6-B FIX Fields Based Upon Other Standards” as it identifies all of these and others including details on the source itself.

Exchange Code: FIX 4.2 and lower use Reuters 2 character exchange mnemonic (i.e. the suffix at the end of a RIC). FIX 4.3 switched to using the ISO "MIC" (Market Identification Code).

Security Ticker: "Ticker" (i.e. in the Symbol field) is more an "understood" vs. standard value. SecurityID and SecurityIDSource can be used to express standard-based values and the standard being used.

Country Code: This is ISO 3166

Currency Code: This is ISO 4217

Chris,

FIX implements these standards:

Exchange Code: ISO 10383 Market Identifier Code(MIC) used in field 30= LastMkt. See FIX 4.3 Appendix 6-C, however many exchanges (including TradeWeb) have not had MICs assigned.

Security Ticker: No standard - field 55= Symbol - but symbols should be ones known to the counterparties.

Country Code: ISO 3166-1 & 3166-2

Currency Code: ISO 4217

See FIX 4.3 Appendix 6-B Vol 6 p 188 for other standards and further information and links.

We are also working with SWIFT through the FIX ISOXML WG to see that standards implemented in FIX that are not ISO find their way into or are interoperable with ISO 15022.
