The configuration to create the mapped symbol. This parameter specifies which tag values must be used for constructing the mapped symbol. The mapped symbol will have the tag values in the same sequence as mentioned in the configuration including the position of occurrence of the repeating group.

This parameter specifies which MarketId/Transport name to be used for fetching the security information of the mapped symbol. By default each configured session in the service monitors uses its own MarketId/Connection/TransportName.

In dual session MARKET_DATA and TRADE_DATA, MARKET_DATA populates the intermediate cache of the mapped symbol to the security definition and TRADE_DATA session can use cache created by setting the configuration parameter to corresponding MARKET_DATA transport name.

In the absence of this parameter setting, user has to send two InstrumentDataRequest(), one with MARKET_DATA transport and other with TRADE_DATA transport to populate the mapped_symbol cache for each session.
