Hi, I suggest you to take a look on this thread that will help you to know at what level you can trade your pokemon. The column « max wild level » is also the max level you can trade. http://forums.pokefind.co/index.php?threads/levelling-information-gen-1-2-3.9805/ Inside there is a link for generation 3 map cuz it’s a bit different than in previous generations. I hope it helped you. Cheers.
