What Each Odds Format Actually Tells You
American odds use a plus or minus sign — a negative number shows how much you'd need to wager to return $100 profit, while a positive number shows the profit on a $100 stake. Decimal odds multiply your total return (stake included) by one clean number, which makes parlay math straightforward. Fractional odds, less common in the US, express profit as a
ratio like 5/2. On cash4midday, the Tennis Point Spread Guide and NFL same-game parlay builder both display in whichever format you've set, so you never have to convert manually mid-session.
