Frequently Asked Questions
What is positive EV betting?
Positive EV betting means only placing bets when a sportsbook's price is better than the true probability of the outcome. Any single bet can lose, but over many bets the edge adds up. AVO's positive EV betting tool finds those prices for you in real time.
How does AVO find positive EV bets?
AVO takes prices from the sharpest markets, removes the sportsbook margin to estimate the fair odds, then compares that fair price against 70+ sportsbooks. When a book offers better than fair, the bet shows up with its EV percentage and expected return.
What devig methods does AVO use?
You can choose between several devigging methods, including multiplicative and additive, and set custom weights for how much each sportsbook influences the fair price. Saved setups let you use different models for different sports or markets.
How much should I bet on a +EV bet?
Most bettors size each bet as a fraction of the Kelly criterion, often a quarter to a half Kelly, so a losing streak does not wipe out the bankroll. AVO shows a recommended stake based on your bankroll and Kelly setting for every opportunity.
Why can you lose money even when every bet is +EV?
Variance. A real edge only shows up over hundreds or thousands of bets, and long losing runs are normal along the way. Tracking closing line value is the best way to judge whether you are getting good prices before the profit shows.
Is positive EV betting better than arbitrage betting?
Neither is better for everyone. Positive EV betting has a higher long-run ceiling but bigger swings. Arbitrage betting removes the outcome risk for a smaller, steadier return. Many bettors build a bankroll with arbitrage and add +EV volume as it grows.
Do I need a separate EV calculator?
No. The expected value, fair odds and recommended stake are calculated for every bet AVO surfaces, so there is nothing to copy into a separate EV betting calculator.
