How are the market values of the players determined?

The market values of players are calculated based on supply and demand within the app. If the player is sold in an above-average number of leagues at a price below his market value, his market value decreases. If, on the other hand, he is bought more often than average at a price above his market value, his market value increases. Our market values are updated once a day around midnight, so that there is always a current daily price for each player.
