In many posts I read that trading items must be done using the item(s) in your game name. I really do not see why this is the best possibility. I understand that it happens that you receive useless items, for example if the player does not have the requested item. So what about the following:
Everyone needs fuel, always. You can never have enough of it. So lets use this fact. Suppose I want to have a spare wire. So I sent this as a gift to my friends. When my friend does not have the item or does not want to receive it, he sends back fuel (20). The only thing I have to do is keep track of this, so I write down my friends name, the item I have send. I will then not sent this item again to this friend. When I receive the requested item, and I do not want to receive it anymore, I sent back fuel. After some time you get a good idea what your friends on your friends list have and what their needs are. I am experiencing that this works. At the end of the day you receive items you want and just have to click it to resent it as long as you need the item. In case of not needing any items, I only send fuel.
