I want to know to exact meaning of each field which we get in Quote service.
for eg: what is the difference between BID and CF_BID field.
Please note that each RIC and Data Feed/Exchange provides different field data and meaning for consumer. I suggest you contact the Content support team to help you check the meaning of your interested RIC's fields via https://my.refinitiv.com web site.
You can use the Refinitiv Data Model Discovery tool to explore content definitions.
CF_BID is a consolidated field for BID. As I know, exchanges may use different fields for the bid. Most exchanges use the BID field while some exchanges may use the PRIMACT_1 field for bid value.
Therefore, CF_BID is created to keep bid value regardless of exchanges. There are rules used to map fields to CF_BID. It uses the RecordType, Exchange, RDNDisplay, and other fields to do the mapping. You can directly contact the content support team via MyRefinitiv for more information.
