“RIC” is used to describe the unique codes used by Thomson Reuters to identify a piece of data. The composition of a RIC is dependent on the type of instrument.

• Instrument code : Can be based on the exchange ticker code, ISIN or local code, currency code, and so on
• Period or time interval : Can be an expiry month code for example
• Delimiter : Usually a full stop used to separate the instrument code from the exchange code or a = sign for money securities.
• Source code : Usually a single or double alpha-character capital unique to an exchange

An equity RIC has several components: the Equity RIC root is in upper case, brokerage characters in lower case (if applicable), and finally an exchange identifier.

Therefore, .NS is a National Stock Exchange. f, ol, and ss are brokerage characters. The brokerage characters for Indian Stock Exchange include:

f indicates an INTER-FII or institutional trade, as mentioned in this FAQ. For more information about the structure of RIC, please refer to this document.
