I am relatively new to ETA Java development. I want to ask if there are additional symbol attributes that we can get via SymbolListHandler or DirectoryHandler (chain rics). I am specifically looking at ISIN and the primary code from the exchange.
Otherwise, can I assumme that the RIC code follows this naming convention
<exchange primary code>.<RIC suffix>
For example, for ASX exchange, can I assumme that the exchange primary code in XYZ.AX to be XYZ?
