I would like to extract the Chain RIC using DSS Rest API, however it seems that I can only extract the actual option RICs for the whole chain but not the Chain RIC with FuturesAndOptionsSearch. Is there any other request that I can use in order to achieve this ? Thank you.
I cannot find any interfaces to extract Chain Options RIC. However, it is possible to manually construct Options Chain RIC from RIC Root. For example, if RIC Root is "EEM.U", the Options Chain RIC will be "0#EEM*.U". The construction rules might vary depending on Exchange. You can contact Content Support team via Get Support for more information.
You can add "PreferredIdentifierType": "RICRoot" in FuturesAndOptionsSearch to search RIC Roots from UnderlyingRICs or use TermsAndConditionsExtractionRequest to extract RIC Root from specific UnderlyingRICs.
Hope this helps.
