Hi Paul,
Only as an end user. I am a contract IT programme manager and it is about 10 years since I actually “did any real work”, tending to spend my time making up stories that various tiers of management will believe.
I think there are settings in the remote access apps that either require a local human to accept a request from a remote accessor, or automatically accept these. In the old days (a decade ago) we used to design these remote access solutions that could also cope with a glitch that required a physical reboot of the machine. That was with a modem connected to the main input power that cycled the power input to the server. Of course, if your home machine is a laptop with a battery, that is not feasible.
Recommendation. Set up the free version of Teamviewer (and as an alternative, the Windows app), and suck it and see. You may also think of investigating whether your broker has a mobile app that allows you access from the mobile phone, if you only wish to enter, manage and exit trades remotely.
