Once you understand the market well, you will be able to identify odds that are skewed from your implied probability, giving you a positive EV over time. The best place to find value is to specialise on niche markets, where the playing field is more level between bookmakers and bettors on an exchange. When the odds in the model differentiate widely enough compared with a bookmaker or other user on an exchange, this is perceived EV. Traders should aim to build their own handicap models, generating their own implied probabilities of a betting market. If you placed £10 on the coin landing on heads at 2.15, the EV is calculated likewise:īy running the calculation again, the EV for a United win becomes + £5.60 for every £50 staked. If however you were offered odds of 2.15 for the coin to land on heads, this is a value bet. This would result in an EV of 0 for either a Head or Tail - because the probability of the two outcomes is the same, so if you tossed a coin infinitely it would theoretically end up all square. Assuming the coin and the toss are fair, each outcome (heads or tails) has an equal probability of 50% - therefore the odds offered on a fair market would be 2.0. Let’s use a coin toss as an example of calculating expected value. (Amount won per bet * probability of winning) – (Amount lost per bet * probability of losing) The formula to calculate expected value for betting is fairly simple: All bettors should be aiming to identify betting value with every bet they make. Positive expected value (+EV) implies profit over time, while a negative value (-EV) implies a loss over time. In betting, the expected value (EV) is the measure of what a bettor can expect to win or lose per bet placed on the same odds time and time again. Expected value is a predicted value of a variable, calculated as the sum of all possible values each multiplied by the probability of its occurrence. This article explains how to calculate and measure expected value, and shows how it can be used to find value bets. Whether you're betting with a bookmaker or on an exchange, calculating the expected value of a trade is fundamental.
