I noticed that during the World Cup various sports books have the same props for different prices. If I take the price at Pinnacle for a given prop and compare it to a different book, can I calculate my edge? I am assuming Pinnacle has the prop priced correctly.
For example..
Pinnacle
Team X vs Team Y: Both teams to score
Yes +150
No -170
--
Sportsbook A
Team X vs Team Y: Both teams to score
Yes +110
No -150
I calculate the Implied Probability ("The win probability that would imply zero vig on the offered line") for Pinnacle "No -170" which is 62.96% using the SBR odds converter tool. I then use the SBR Kelly Calculator and input the 62.96% into the Win Probability. I then input -150 into the odds for the Sportsbook A's "No". The Kelly Calculator reads that I should be betting 7.4% of my roll for this bet.
Considering Pinnacle "Yes" is +150 did I just make a bet with zero ev or was it +ev?
