What Is Implied Probability?
Removing the Vig

Das Konzept

Implizierte Wahrscheinlichkeit = 1 ÷ Dezimalquote. Quote 2,50 = 40%. Quote 1,80 = 55,6%. Wenn Sie die reale Wahrscheinlichkeit höher einschätzen: das ist eine Valuewette. Profis suchen NUR Valuewetten mit positivem Erwartungswert.

Marge Eliminieren

Quoten enthalten die Buchmacher-Marge. Um faire Wahrscheinlichkeiten zu finden: alle Wahrscheinlichkeiten addieren und jede durch die Summe teilen.

⚡ CalcWolf Insight

Sharp bettors at Pinnacle Sports move lines. If Pinnacle has a game at -3 (-110/-110) and DraftKings has it at -2.5 (-110/-110), the DraftKings line likely has value on the underdog. Following Pinnacle line movement is one of the most reliable edges in sports betting.
