Example
A 3% edge means you have a 3% expected return on investment.

Expected Value (EV)
The average amount you can expect to win or lose per bet if you were to place the same bet many times. Calculated as: (Probability of Winning × Potential Profit) - (Probability of Losing × Stake). A positive EV (+EV) indicates a profitable bet over time.
+EV (Positive Expected Value)
A bet where the expected value is greater than zero, meaning the true probability of winning is higher than what the odds imply. These are the opportunities EVSignals identifies.
-EV (Negative Expected Value)
A bet where the expected value is less than zero. Most bets offered by sportsbooks are -EV due to the built-in margin (vig/juice).
Fair Odds
The odds that would result in zero expected value - where the implied probability exactly matches the true probability. Also called 'true odds' or 'no-vig odds'.
