Hi @Roy Chan
You can refer to the REUTERS Info pages i.e. if you subscribe to the RIC 'REUTERS' this will give you a list of other info page RICs e.g. EQUITY, BONDS - by navigating these you can usually get this type of information.
So, for example I found traversed down the 'COUNTRIES' RIC to find the main US Exchanges info RIC is 'US/EXCH1' which then list the sub-pages such as 'US/EXCH2' for NYSE and so on.
Note the RIC should be requested without the above 'quotes'.
For the consolidated RIC mapping you should contact our content / data helpdesk via the Contact Us page.
You can use a RFA / EMA /ETA example Consumer app to consume the above pages - or you can use the SpeedGuide tool on the downloads section (under Elektron SDK Tools) for easier navigation of the Info Pages.
