Hello @austin.fan01 ,
My first and probably best suggestion will be to work with Refinitiv content experts to pinpoint the way to do this search via Datascope GUI. The approach that you come up with we will try to reproduce via DSS REST API.
Additionally, I would like to discuss a potential approach that I have researched:
The indices for NAS exchange can be identified, for example, via HistoricalCriteriaSearch
{{protocol}}{{host}}{{api}}Search/HistoricalCriteriaSearch { "Request": { "RicPattern": null, "BondTypeCodes": null, "ContributorIds": null, "CountryCodes": null, "CurrencyCodes": null, "ExchangeCodes": ["43"], "FutureMonthCodes": null, "InstrumentTypeCodes": ["22","118"], "OptionMonthCodes": null, "OptionTypeCodes": null, "CouponRate": null, "StrikePrice": null, "ExpiryDate": null, "MaturityDate": null, "Range": { "Start": "2022-11-07T00:00:00.000Z", "End": "2022-11-08T00:00:00.000Z" } }}
There is no provision to filter on request either on GICs or on TRBC codes.
If your indices are equity indices, you can also do:
{{protocol}}{{host}}{{api}}Search/EquitySearch{ "SearchRequest": { "AssetStatus": "Active", "AssetCategoryCodes": ["EQI"], "SubTypeCodes": null, "CurrencyCodes": null, "CompanyName": null, "Description": null, "DomicileCodes": null, "ExchangeCodes": [ "NAS"], "FairValueIndicator": null, "FileCodes": null, "GicsCodes": null, "OrgId": null, "Ticker": null, "Identifier": null, "IdentifierType": null, "PreferredIdentifierType": null }}
However, from my testing, GicsCodes filter will not be effective for indices- because for indices this content is not populated.
In step 2, Via TermsandConditionsRequest I request TRBC and GICS information on the indices RICs obtained from step 1:
{{protocol}}{{host}}{{api}}Extractions/ExtractWithNotes{ "ExtractionRequest": { "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest", "ContentFieldNames": [ "RIC", "CUSIP", "ISIN", "SEDOL", "Issuer OrgID", "Currency Code","TRBC Business Sector Code","GICS Industry Code" ], "IdentifierList": { "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList", "InstrumentIdentifiers": [ { "Identifier": ".BANKT", "IdentifierType": "Ric" }, { "Identifier": ".NQPL60LMEURN", "IdentifierType": "Ric" }, { "Identifier": ".NQASPA5010JPYN", "IdentifierType": "Ric" }, { "Identifier": ".NQASPA5010LM", "IdentifierType": "Ric" } ] } }}
Resulting in:
{ "@odata.context": "https://selectapi.datascope.refinitiv.com/RestApi/v1/$metadata#DataScope.Select.Api.Extractions.ExtractionRequests.ExtractionResult", "Contents": [ { "IdentifierType": "Ric", "Identifier": ".BANKT", "RIC": ".BANKT", "CUSIP": null, "ISIN": null, "SEDOL": null, "Issuer OrgID": "70344", "Currency Code": "USD", "TRBC Business Sector Code": "5510", "GICS Industry Code": null }, { "IdentifierType": "Ric", "Identifier": ".NQPL60LMEURN", "RIC": ".NQPL60LMEURN", "CUSIP": null, "ISIN": null, "SEDOL": null, "Issuer OrgID": "70344", "Currency Code": "EUR", "TRBC Business Sector Code": "5510", "GICS Industry Code": null }, { "IdentifierType": "Ric", "Identifier": ".NQASPA5010JPYN", "RIC": ".NQASPA5010JPYN", "CUSIP": null, "ISIN": null, "SEDOL": null, "Issuer OrgID": "70344", "Currency Code": "JPY", "TRBC Business Sector Code": "5510", "GICS Industry Code": null }, { "IdentifierType": "Ric", "Identifier": ".NQASPA5010LM", "RIC": ".NQASPA5010LM", "CUSIP": null, "ISIN": null, "SEDOL": null, "Issuer OrgID": "70344", "Currency Code": "USD", "TRBC Business Sector Code": "5510", "GICS Industry Code": null } ],
I.e. TRBCs appear to be populated, while GICS are not.
Therefore, if one is able to come up with the list of required TRBCs, in step 3, one should be able to further filter the result from step 2, not request, but result, for example, keeping indices where TRBC = 5510
This approach may allow to arrive at the results you are looking for, but by working out the search via GUI and emulating it via API, you can potentially come up with a better solution. Once you have the GUI-driven approach- let us know, and we will try to help to migrate it to DSS REST API.
