Trade opportunity value

As it is right now, the value of the cards that a person needs from your tradelist is based on the value of the cards you have, not the value of the cards they want. Among other situations, this means that if I have a foil on my tradelist and they have a non-foil on their wishlist the foil value will get used, artificially inflating the value of the cards they need from me.

This will happen with any other printing that is more valuable than the cheapest copy: Foil, most promos, sometimes older printings (Alpha, Beta, Legends etc), FTV and probably some others. I'm not sure exactly the best way to go about calculating total trade value, but for sure this doesn't seem like the correct way.
