FAQ

Questions Kelly Criterion Sizing owners ask.

  • 01

    What is the difference between Pure Kelly and Half Kelly?

    Pure Kelly calculates the maximum mathematically optimal percentage of your bankroll to wager. Half Kelly divides that result by two, providing a safer buffer against volatility and estimation errors.

  • 02

    How do I use American odds with this capability?

    You can input standard American format odds, such as -110 for favorites or +150 for underdogs. The get_net_odds_ratio capability will handle the conversion to a profit ratio automatically.

  • 03

    Can I verify if my win probability is valid?

    Yes, you can use the validate_betting_parameters capability to check if your win probability (between 0 and 1) and American odds are mathematically valid for calculation.
