How can I trade between pokemon x and y

I have a mac and i have both pokemon x and y. Is it possible to trade with myself?

Open two citra screens and try the web services

open two citras, regenerate a new ID on the second one, then launch the game on both, then host a room on one and connect with the other, you’re prob gonna need to use your IPv4 thing to connect tho, which you can find by going to command prompt and typing “ipconfig /all” and scrolling up a bit.
