Exchange commission
Exchange commission is the percentage a betting exchange charges on net winnings, in place of building a margin into its odds.
Because an exchange matches users against each other, it earns by taking a small commission on winning bets rather than shading the odds. Commission rates differ between exchanges, which affects the true value of a lay price.
A matched feed accounts for the exchange when it rates opportunities, so the rating reflects the layable price rather than a headline number.
