Positive EV: the price is better than the chance deserves. It shows up over many bets; any single bet can still lose.
How it works
EV = chance × profit if it wins − (1 − chance) × stake. Positive EV means the price is better than the chance deserves.
EV only shows up over many bets; any single bet can still lose. The chance you enter is an estimate — a fair price from the no-vig calculator is a common one.
