Is it possible to obtain the list of currently traded treasuries or in that case any items for a given service? I have access to a certain service but I have no information about any of the items traded there. I only know that there are supposed to be US Treasuries like US5YT or US10YT but no records of them could be found. How do I find them?
There is no such consolidated list. The items available for subscription are based on the permissions associated with your account. The best place to find a suitable RIC code for an instrument is the RIC search tool on the developers portal.
Other resources which you may find helpful is the Speed Guide Tool. Configure it to connect to your infrastructure and then you can navigate the page based layout by clicking.
