Trade scores are still way out , imo they should be done on a default value and advised on the players card.
EG: John Smith
- your rating 1000
- default rating 800
At least that way you can see how other people might rate a player. You might wangbtl trade for my RB who I might value higher, therefore just because the trade meter says it's fair doesn't take into account how much I place on that player.
Best of luck with the trade
