Hi,

I'm using TermsAndCondistionsExtractionRequest to obtain the expiration date of "

EV3W1035W7"

var extractionRequest = new TermsAndConditionsExtractionRequest
{
IdentifierList = InstrumentIdentifierList.Create(new[]
{
new InstrumentIdentifier {Identifier = "EV3W1035W7", IdentifierType = IdentifierType.Ric}
}
, new InstrumentValidationOptions
{
AllowHistoricalInstruments = true
}, false),
ContentFieldNames = new[] { "Put Call Flag", "Strike Price", "Underlying RIC", "Expiration Date", "Thomson Reuters Classification Scheme" },
Condition = new TermsAndConditionsCondition
{
IssuerAssetClassType = IssuerAssetClassType.AllSupportedAssets,
}
};

This request returns blank for expiration date, put call flag, strike price, underlying ric and thomson reuters classification scheme.

I would like to know how best to obtain these information for any historical options.
