I actually changed the meter because people were complaining that it was letting trades through that were in the yellow and red. But the actual calculation is being more relative so good higher-end trades should go through and bad lower-end trades should get blocked.
However, if you feel that a trade is not being let through that should, feel free to PM me the league, team, and what you are trying to put on each side, and I'll be happy to look and see if the algorithm needs to be adjusted.
