I opened my VPS through fast hosts very easily by visiting there site.
I have ever had a problem , but installing MT4 was tricky . First make sure the windows version on your VPS will support Mt4 … You can always email support to find out.
Than on your computer side your correct broker MT4 will need to downloaded (not vps side )…
Right click the .exe install file and copy than on vps copy to desktop... This is how I did it but if the copy isn't enabled on the vps use a memory stick or email the file to your self and open email on vps.
Hope this helps..
