Slam Wager glossary

Expected value

Expected value estimates the average profit or loss per wager under a stated win-probability assumption and quoted payout; it is not a prediction of one result.

Also called: EV, positive EV, +EV

How to interpret it

Per unit staked, expected value equals win probability multiplied by net profit when winning, minus loss probability multiplied by the unit at risk.

A positive calculation depends entirely on the probability input and price being accurate. It does not guarantee a profit in any sample.

Limits and responsible use

  • Model error, stale prices, limits, void rules, correlation, and estimation uncertainty can make a displayed estimate incomplete or wrong.

Do not use an EV label to justify chasing, borrowing, or exceeding a preset limit. Recheck the exact market and live price before acting.
