Definition
The price on a bet, written the way your sportsbook writes it: American (-110, +150), decimal (1.91, 2.50) or fractional (10/11, 3/2). They all say the same two things: how much you win for what you risk, and the chance the price implies. -110, 1.91 and 10/11 are the same price. You can switch the format in your account settings.
