Trade with myself pokemon ultra sun/moon

is it possible to trade myself by opening 2 games on my pc to get Gengar, Alakazam and pokemons that need trading to evolve?

i think its possible. You probably have to use PKHEX

i’ve been told about that its just that i cant seem to find my save game anywhere i cant quicksave i just save the game by the pause menu in-game like if i where playing on nintendo

You can trade with yourself in Citra. Steps to do this were posted abundantly, just search for “trade with self”.
