I use a separate computer for trading only. Not for mails or other programs. It is password protected and i see to it that i have at all times a recent image ready in case of a failure.

How about the internet on your computer?
You have to make sure your internet connection is stable.

Unfortunately mine isnt really that stable. As a solution Im thinking of getting a separate device where you basically have a fixed 4G connection and you connect only your laptop to it.

How do you guys handle these issues?

This is what could happen if you use the same computer as the family.
warning: this is pretty tragic

I've one direct Hathway connection and 2 separate mobile devices that work on 4G, while trading I use 4G only, and other times hathway.

Both of them are fairly cheap options here, for you I don't know but I would also recommend similar arrangement. Internet going bust is very common issue here too.
