Betting exchange

A betting exchange is a marketplace for customers to bet on the outcome of discrete events. Betting exchanges offer the same opportunities to bet as a bookmaker with a few differences. Gamblers can buy (also known as "back") and sell (also known as "lay") the outcome, and they can trade in real-time throughout the event, either to cut their losses or lock in profit. Bookmaker operators generate revenue by offering less efficient odds. Betting exchanges normally generate revenue by charging a small commission on winning bets.
