This scenario is supported in any Windows VPS plan, with any version of Windows and any VPS power. The real options you need depend on advisors you will be running. Usually advisors are not resource-hungry and will run just fine in any VPS. But some may require more computation power or RAM.
Forex VPS and Server Reboots
Sometimes your Windows server will reboot for whatever reason. This may be updates, or software crash, or V3next fault, or many other things that may happen. We are doing our best to avoid any of them, but they happen sometimes and you should be ready.
