Hi @jzhao

Do you mean "Arca N.A. Telecom Index"?
The Arca N.A. Telecom RIC is .XTC or 0#.XTC for chain.

I suspect that you are upgrading from an old version that use 4-part subject name convention.

.NaE means "not from the exchange". It is used in the old 4-part subject name convention where request subject must consist of "<Server>.<Service>.<Item>.<Exchange>".

RFA 8.0 nolonger use 4-part subject name and doesn't need .NaE extension with consolidated RICs anymore.

If you are looking for other RICs, you can use our RIC search tool

Hi @Warat B. Thank you very much for the reply. You're right that we're upgrading from the 4-part subject name convention. Yes the RIC symbol ".XTC" works fine. However I didn't find any documentation describing the conventions. Thank you.
