Understanding Odds
American OddsCommon in the US. Negative numbers (e.g. -110) show how much you must bet to win $100. Positive numbers (e.g. +150) show how much you win on a $100 bet.
Decimal OddsUsed globally and in professional models. They represent the total payout (stake + profit). For example, 2.00 means you get $2 back for every $1 bet.
Implied ProbabilityThis is the conversion of odds into a percentage. It tells you how often the bet needs to win for you to break even.
The "Edge"If your estimated probability of an event winning is higher than the implied probability, you have found a "Value Bet" with a positive expected value (+EV).
