After you finished the main story of the game, yes you can trade. A Pokemon transfer is on Route 15.
you can transfer Pokemon from Pokemon platinum to black and white but you can't trade from black to platinum
You can't, you only can transfer Pokemon Platinum Pokemon to Black and White. I repeat, YOU CAN'T.
No, but you can transfer from platinum to black or white using poketransfer of relocater.
You cannot trade, but you can use the relocator with two ds's and transfer Pokemon from platinum to white
You can never trade Pokemon from Black to Platinum, because Generation V Pokemon do not appear in Platinum or any other game before Black and White. However, you an transfer Pokemon from Platinum to Black after you beat the game.
you cant you have to get a celibi from game stop and trade it in to Pokemon black or white
you cant but you can transfer platinum Pokemon to black or white only if you beat the elite 4
because pokemon platinum has 4th generation pokemon. Pokemon black and white contain 5th generation pokemon
*heart and btw get a life :)
if you have it on HG, SS, Diamond, Pearl or Platinum yes
Unfortunately, in Pokemon Black and White, you cannot interact, (trade, battle etc.), with the other versions, (Platinum, Silver, Emerald etc.). only with Black and White is where you can interact.
no you must poketransfer platinum Pokemon from the game to black/white. just like pal park: beat elite four to unlock
