Configuration

kelly-b-parameter-format

Specifies the format of the b parameter. Supported formats:

• fractional-odds (default): Prompts for fractional (British) odds (e.g. 3).
• decimal-odds: Prompts for decimal (European) odds (e.g. 4).
• moneyline-odds: Promps for Moneyline (American) odds (e.g. 300).
• implied-probability: Prompts for the implied betting odds probability (e.g. 0.25).
• implied-percent: Prompts for the implied betting odds percentage (e.g. 25%). (The percent symbol is optional.)

kelly-fraction

A multiplier applied to the computed Kelly fraction. The default value of 1 uses the full Kelly recommendation, while a value less than 1 scales the wager down proportionally.

kelly-bankroll

Sets your total available funds for wagering. If left as nil, you’ll be prompted to enter a value when running kelly for the first time.

kelly-bankroll-currency

Specifies your currency symbol (default is "$").
