When we use MQL5 VPS . it's like other VPS services we will access via specific IP and using windows as platform ?
If not then it means just migration of MT4 setup include our any EA running or hidden and this image below charge for only 1 terminal?
Yes, you don't have access to a computer environment, you only migrate your EA or signal and everything is done in the background, you can only see the journal.
One account only.
No it's not the same as an RDC remote desktop connection.
