@lei.cheng - This is a private post

Considering your query, we moved it from the DSS to the TRTH forum, it seems more appropriate, and will help people discover it. AHS

@lei.cheng,

First of all, there are several issues with your call, it will fail:

  • Comma after the "]" just after the InstrumentIdentifiers declaration must be removed
  • The ElektronTimeSeries extraction request does not deliver those 3 price fields, the correct field names are: "High", "Open", "Low"
  • The Condition must include this: "ReportDateRangeType": "Range",

I changed the call to this to have it run without error:

{
  "ExtractionRequest": {
    "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.ElektronTimeseriesExtractionRequest",
    "ContentFieldNames": [
      "Settlement Price", "Volume", "High", "Open", "Low"
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
      "InstrumentIdentifiers": [{ "Identifier": "CMAL3", "IdentifierType":"Ric" }]
    },
    "Condition": {
      "ReportDateRangeType": "Range",
      "QueryStartDate": "2017-01-01T00:00:00.000Z",
      "QueryEndDate": "2018-08-30T00:00:00.000Z"
    }
  }
}

This ran, and delivered all fields except the Settlement price, which was always empty (even though I extended the date range to start in Jan 2017).

Explanation: that is simply because there is no settlement price for instrument CMAL3, which is a commodity future. Try an equity (for instance CARR.PA), you will get Settlement Price values.
