The user defined identifier fields can be added to each identifier. Up to 6 user defined identifier fields are available, (UserDefinedIdentifier, UserDefinedIdentifier2, UserDefinedIdentifier3, UserDefinedIdentifier4, UserDefinedIdentifier5, UserDefinedIdentifier6). These fields are simple text fields designed to allow the user to associate their own identifying string to the instrument which can be passed through to extraction result. The user defined identifier values can be added were ever the instruments are defined by using the appropriate user defined field, (shown above).

Here is an example of populating the user defined identifiers using the ExtractionRequests.EndOfDayPricingExtractionRequest method:
