Can you elaborate on how a "trading system" should work?

Like trading items with other students for example I had a book so one needed for the classes and they had galleons, they can trade galleons or trade another item for what they want

Like this, so that you have to both agree to the trade, and you can trade an item for an item (or galleons) and meanwhile be sure that the other person won't keep your item yet won't trade you theirs?

Are there even new books?
