What does the following warning messages mean and what should the application do?

There is functionality within the RFA that can be implemented as part of the TREP or Elektron infrastructure or within the client itself. The notifications are to indicate that the infrastructure is not supporting such features so they are enabled in the API instead. Enabling in the API can mean additional CPU overheads when processing large number of instruments.

Advanced Symbol Lists support a feature whereby you can tell the provider to also send all constituents of the list as well as the list meta-data itself. This saves on the round trip times on the list meta-data and having to subscribe to each instrument separately.

Steven, thank you for the answer. I will check my TREP configuration file and license to find out why these features are not enable in the TREP infra.

@Akechi Sato also discuss with your account manager for the particular service you are receiving, some features are only implemented with Direct Feeds and not Elektron Edge.
