Test your ideas when you get back home and enjoy yourself while traveling. My wife would divorce me if i would work while we are traveling and rightly so.
Not traveling with wife or anyone ... i have been to these places tens of time, i have time to kill, so please stay on subject. if you can't, then don't worry about it.
Buy a laptop...they're inexpensive these days and the same with laptop backpack / travel bag considering you stated traveling around countries. Don't go cheap on a simple solution. It's what I do when flying between South France, Canada and U.S...I like to travel light...very little complication other than being pinned down in one country by a Coronavirus lockdown. wrbtrader
Can use remote control apps also through a tablet I believe. All this because the OP doesn't want to spend $200 on an used small laptop. Talk about being spoiled.
Yes you can. Install a VM on the external device, which is more secure anyway. Load TWS. Install a client app and load the VM in any computer you use.
Buy a small foldable laptop or something like Microsoft Surface. Encrypt the entire disk/system in case stolen. They are very affordable.
