@bilou_12,

In the first result (the search for historical chain constituents between 1996 and 2019) you found ACCOB.O, but in fact it was last quoted in June 1999, which explains why a request for data in 2019 delivers null values: there is no data.

This can be easily verified in the GUI:

If you run the first search using the same dates as those for your data request, then you should not run into this type of issue.

Hi

Thanks for your quick answer!

I made a mistake with the copy paste but the same query to fetch the prices for a range involving 1996-1999 also returns nothing:

{     "ExtractionRequest": {         "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.ElektronTimeseriesExtractionRequest",         "ContentFieldNames": ["Trade Date", "RIC", "Open", "High", "Low", "Universal Close Price", "Volume"],         "IdentifierList": {             "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",             "InstrumentIdentifiers": [{                 "Identifier": "ACCOB.O",                 "IdentifierType": "Ric"             }],             "ValidationOptions": {                 "AllowHistoricalInstruments": true             },             "UseUserPreferencesForValidationOptions": false         },         "Condition": {             "ReportDateRangeType": "Range",             "StartDate": "1996-01-01T00:00:00.000Z",             "EndDate": "2019-10-03T23:59:59.999Z"         }     } }

Could you please advise?

@bilou_12,

Apologies for the late answer, I did not notice you posted a fololow-up query. The key here is in the extraction notes:

WARNING: RIC \"ACCOB.O\" is not available in Elektron Timeseries web service.

That instrument being very old, it looks like there is no EoD data for it in the database. That said, I'm no a data specialist, so I cannot explain any further.
