How to Prepare a Trading Account for Migration to Virtual Hosting
Products purchased on the Market and launched on the chart are also moved during migration. They remain completely functional, and the number of available activations is not decreased. Automatic licensing of purchased products without spending available activations is provided only for the virtual terminal.

Why Virtual Hosting On The MetaTrader 4 And MetaTrader 5 Is Better Than Usual VPS
Renting a virtual server right from the MetaTrader 4 and MetaTrader 5
terminals is the optimal way to ensure uninterrupted work of your
trading robots and Signal
subscriptions. Essentially, it is an analogue of a VPS though it is
better and more suitable for addressing needs and challenges that a
trader comes across. The server can be rented straight from your
MetaTrader. It takes only a couple mouse clicks for Experts Advisors,
indicators, scripts together with Signal subscriptions and settings to
be transferred to the virtual server. The Virtual Hosting Cloud network
was developed specially for MetaTrader and has all the advantages of a native solution.
With Windows' Remote Desk Connection you can open a window of the remote vps on your home pc and in this you can watch and manage the terminal there!
But you can login into your account with the investors password just to watch..
