Hi Preshan,

Here's an example of C# for On Demand - Intraday Pricing for DSS REST API using "InstrumentValidationOptions": AllowOpenAccessInstruments = true

Request:

var ExtractionsContext = new ExtractionsContext(new Uri("https://hosted.datascopeapi.reuters.com/RestApi/v1/"), "<your user id>", "<your password>");


//Create the request
var extractionRequest = new IntradayPricingExtractionRequest
{
 IdentifierList = InstrumentIdentifierList.Create(
 new[] {
 new InstrumentIdentifier { Identifier = "XS1452710962=BARL", IdentifierType = IdentifierType.Ric },
 new InstrumentIdentifier { Identifier = "XS1452800797=BARL", IdentifierType = IdentifierType.Ric },
 new InstrumentIdentifier { Identifier = "XS1452801175=BARL", IdentifierType = IdentifierType.Ric }
 },
 new InstrumentValidationOptions
 {
 UseExchangeCodeInsteadOfLipper = true,
 AllowHistoricalInstruments = false,
 AllowOpenAccessInstruments = true,
 ExcludeFinrAsPricingSourceForBonds = false,
 UseConsolidatedQuoteSourceForCanada = false,
 UseConsolidatedQuoteSourceForUsa = false,
 UseUsQuoteInsteadOfCanadian = true
 }
 , false),
 Condition = new IntradayPricingCondition { ScalableCurrency = true },
 ContentFieldNames = new[] {
 "RIC", "Ask Price", "Asset Type", "Bid Price", "Currency Code",
 "Exchange Code", "High Price", "Instrument ID", "Instrument ID Type", "Low Price", "Open Price", 
 "Previous Close Date", "Previous Close Price", "Security Description", "Settlement Price", 
 "Trade Date", "User Defined Identifier", "Volume" }
};

//Extract - NOTE: If the extraction request takes more than 30 seconds the async mechanism will be used. See Key Mechanisms 
var extractionResult = ExtractionsContext.ExtractWithNotes(extractionRequest);
var extractedRows = extractionResult.Contents;

//Output
if (!extractedRows.Any())
 Debug.WriteLine("No rows returned");
else
{
 foreach (var row in extractedRows)
 Debug.WriteLine(
 row.Identifier + " (" + row.IdentifierType + ") " +
 String.Join(", ", row.DynamicProperties.Select(dp => dp.Key + "=" + dp.Value)));
}
//Output Notes
Debug.WriteLine("NOTES:");
foreach (var note in extractionResult.Notes)
 Debug.WriteLine(note);
