Can you trade between Pokemon Pearl and Diamond online using one DS?

I have only one DS. My brother has a Diamond version and I have a Pearl version. So we both share. We want to trade between the both of us, and decided to use the Global Trade Station. However, we are not quite sure if it is possible. What if someone else gets our pokemon, or we cannot trade from the same internet port?|||You can do what you wanted to do and use the GTS. But make sure you do it quick because you'll never know if someone else is just waiting for the Pokemon you just put up.|||you could put it on gts but what you need to do is when you pick which pokemon you want, put down the pokemon you are going to trade your brother for example if you are trading a lv 50 gyrados and your brother is offering a lv 60 torterra you would deposit your pokemon and put the pokemon you want as a torterra lv 60 and up and what ever gender it is


all your brother has to do is find it|||you would need two Nintendos and go under pokemon center using wifi..but using one ds at gts anyone could take the pokemon just trade with the people on gts it does not have to be your brother you trade with right? it'd be easier for you just to find a friend that'll let you borrow his/her ds or just trade with others worldwide whats the difference?|||You need two Nintendo DS's to trade with someone. You should read more about the GTS in your Pokemon Diamond and Pearl Instruction Manuals.
