I'm trying to request RICs using QuoteID. I've noticed for some companies, mostly from ARCA and NYSE, when requested the RIC with QuoteID using TR.RIC I get symbols without any of the dot extensions. For example, for 55839008181 (American Shared Hospital Services) I was expecting something like AMS.N, or AMS.ARC but only AMS was returned.
And this is "strange" for me, since normally RICs are with this "dot extension", this (and others from that same exchange) didn't had any. Is there a reason for it?
What methodology would suggest to acquire the RIC with that "dot extension form" for these cases? Is there a way to retrieve the primary exchange of the company with a TR formula, using the QuoteID?
Thanks for your time!
