Can we use RFA C++ API to receive real-time data using ISIN and not RIC codes. I know this can be done via DSS however customer is a real-time subscriber already and would like minimal change.
TREP APIs supports only RIC codes. Basically you have to use RIC code to request real time data from Elektron. If you want to use ISIN, you have to use other API such as DSS to convert it to RIC code and pass it to TREP API/ RFA.
