I dont know about those feeds but coinexx isnt coming up as a broker in the mt5 android app. I did contact them through the website chat in regards to it and i was told it was a known issue and they are working on it. I dont know how reliable is the chat. This was a few days ago.
One of my first jobs was at a super market. When i seen vendors pulling out, i knew something was up. Few days later the company went bankrupt. Maybe im being paranoid af but im hoping this isnt the case!
