I'm making a TickHistoryTimeAndSalesExtractionRequest request. I get values back for everything except the currencies are missing. I need theses in the message so I can scale from GBp to GBP,etc.

I get back rows with 8 values (RIC, Date,Time,etc....Price,Volume,Trade Price Currency)

Currency is always empty. How can I update my request to receive the currency. I got "Trade - Trade Price Currency" from the available fields list. Is there a different field I should be looking at?

string[] _fieldNames = { "Trade - Price", "Trade - Volume", "Trade - Trade Price Currency" };

var request = return new TickHistoryTimeAndSalesExtractionRequest
            {
                Condition = new TickHistoryTimeAndSalesCondition
                {
                    ReportDateRangeType = ReportDateRangeType.Range,
                    QueryStartDate = startDateUtc,
                    QueryEndDate = endDateUtc,
                    ApplyCorrectionsAndCancellations = false,
                    ExtractBy = TickHistoryExtractByMode.Ric,
                    MessageTimeStampIn = TickHistoryTimeOptions.GmtUtc,
                    SortBy = TickHistorySort.SingleByRic,
                    DisplaySourceRIC = false
                },
                ContentFieldNames = _fieldNames,
                IdentifierList = instrumentIdentifierList
            };

var result = extractionsContext.ExtractRaw(request);
