Retrieving Constituent RICs under a Chain RIC

Hello Team,

Is there any way to retrieve constituent RICs under a particular Chain RIC without using a regular DSS template like EOD, Intraday, Composite etc.,

Like how we can use the search function on DSS Web GUI to find the Constituent RICs under a Chain RIC. I have tried to search for the API on API Reference Tree and could not find any. All I found was Historical Chain RIC Search and that is for TRTH and it does not serve the purpose here.

If you can share the API associated with this, it will be helpful.

Sample Chain: 0#NGMM:

Hello @Anirudh Vishnubhatla

I have used TermsAndConditionsExtractionRequest for chain expansion - which should be available to DSS users. Most searches - InstrumentSearch etc do not accept Chain RIC as an identifier.

You can raise a ticket for this content question at LSEG MyAccount.

Hello @Gurpreet,

Thank you for checking this and providing a solution. I did inform this to the client. But the challenge is, the client has access to EOD, Intraday and Elektron EOD Templates only on DSS. And using the entire chain to extract the data will eat up the quota that the client has for these templates. Hence, client was asking for an alternative like Instrument Search to expand the Chain RIC and provide the constituents.

You already knew from the API Reference Tree that the API does not provide any search endpoints for expanding a chain RIC for DSS users. Moreover, the Chains Search on the DSS Web GUI didn't expand a chain.

Another method could be the Search/FuturesAndOptionsSearch with the following request.

{

    "SearchRequest": {

        "FileCodes": null,

        "CurrencyCodes": null,

        "ExchangeCodes": [

            "EDX"

        ],

        "StrikePrice": null,

        "ExpirationDate": {

            "@odata.type": "#DataScope.Select.Api.Search.DateValueComparison",

            "ComparisonOperator": "GreaterThanEquals",

            "Value": "2025-01-01"

        },

        "IdentifierType": "RICRoot",

        "Identifier": "NGMM",

        "PreferredIdentifierType": "Ric",

        "AssetStatus": "Active"

    }
