Ah yes.
(Ony a better train for internet now)
Checking my samples, chat doesn’t get the conversion data.
I doubt the’d add that to chat, since chat only draws the users paid in currency, so the “extra” data isn’t needed in chat.
If you need the US values you’ll have to wait till Twitch gives us some “proper” API rather than just chat.
Just make sure to add a comment to my uservoice about the currency conversion notes.
