Single post in Recent Trade with a Single Person

It sounds like you're asking to see another user's trade history, which - forgive me for being blunt - is none of your business. Believe it or not, there's no rule saying someone can't resell a pokemon you sold them. If you don't want people doing that, you can refuse to trade with them if you've seen them reselling your pokemon. I wouldn't want someone to see my recent trade history. Not because of anything bad - I'm not ripping anyone off by any means - but because I just think it's an invasion of privacy.
