Any ideas on how to get the related securities / primary RICs for equities using the api?
It doesnt look like there is a DIB field either.
You cannot use Eikon Data APIs to extract data from "All Quotes" app.
You can contact Refinitiv Helpdesk to confirm if there is any fields on Data Item Browser which carry related securities.

For primary RIC, I think you can use TR.PrimaryQuote, TR.PrimaryRICCode, TR.PrimaryInstrument fields. (Please also double confirm content question with Refinitiv Helpdesk)
