This product offers both traditional bookmaker bets (Back) and exchange bets (Lay). You can switch to the 'Exchange' view to access 'Lay' options, which allow you to bet against an outcome. For example, you can 'Back' Manchester City to win or 'Lay' Manchester United, meaning you're betting they won't win (a draw or loss). Importantly, this product allows Lay bets on both exchange and bookmaker odds.

Remember, a 'Back' bet is for an outcome to happen, while a 'Lay' bet is against it. Your potential loss on a 'Lay' bet is the potential profit of the opposing 'Back' bet, and your profit is the opposing 'Back' bet's stake.
