Same-game parlay

A same-game parlay, or SGP, combines two or more bets from one game into one ticket. Its legs can depend on each other. A team winning and the game going over can tend to happen together, or work against each other.

Books price these tickets with their own view of how the legs relate, so the same ticket can carry different prices at different books.

Start with each leg's chance, then ask whether the legs tend to win together. If they do, the real chance of the ticket is higher than the product of the single chances. If they work against each other, it is lower.

Compare the book's price with the fair price for the same ticket. A different view of how the legs connect gives a different fair price, so the two numbers may not match.

The Parlays tab can build same-game parlays. Turn on Same-game parlays, and Antic pairs two legs from one game. It only pairs legs that move together: never opposite teams, never an over with an under, and never both sides of one market.

You can rank pairs toward expected value (Max EV), toward hit rate (High hit rate), or in between (Balanced). You can also set the correlation, shown as ρ, to 0.20, 0.30, 0.42 or 0.55. The default is 0.42, and Antic says ρ is an assumption, not a measurement.

Treating the correlation as a measured fact. ρ is an assumption, so a pair that ranks high in Antic can play out differently in a real game.

Using only the fair price. The book prices the ticket with its own correlation, so compare its quote with the fair price shown on the card.
