How do sportsbooks calculate betting odds?

[Heatman]

I've been wondering how sportsbooks calculate their betting odds. Personally, I believe it's done with a program because there's no way someone can individually do that one by one for all games.

Do you know how sportsbooks calculate betting odds?

I've wondered that myself, because the odds can be different depending on which sportsbook you use.

I use blightybets.com to compare offshore sportsbooks, and their odds are often better than UK sites. The variations you mention come from different algorithms and margins each bookmaker uses. Programs do calculate them, but human traders adjust for sharp moves. Crypto-friendly books at blightybets.com offer even more competitive lines.
