If you are looking for a free forex vps, then you should check Amazon Web Services.
For the first year, this forex vps is provided totally free from Amazon Web Services.
After one year, you will need to pay.
So in essence for 1 year, you are getting a very good forex vps totally free.
I have posted videos in the post also that explain how you are going to open the account with Amazon Web Services.
One you have opened the account, the videos will guide you how to install the forex ea on the vps.
