Hello Gert,
Yes, as far as I know, they are reliable. They are a long time on the market. And the good thing is they guarantee they have the same live and demo data which is very important for us. However, I never used them, but I am planning to start next week because I want to use the new data that Forex Software provides.
We will do our best to place the tool for data from next week.
But keep in mind that for the moment, the data in EA Studio comes from JFD. I will let you know when they switch it.
Cheers,
