Function implied_precision_asymmetric 

pub fn implied_precision_asymmetric(
    target_sharpe: f64,
    annual_bet_frequency: f64,
    payout: AsymmetricPayout,
) -> Result<f64, StrategyRiskError>

Smallest precision in [0, 1] at which an asymmetric-payout strategy reaches target_sharpe (AFML §15.3, Snippet 15.3), found as a root of the quadratic in p.

Errors

• StrategyRiskError::InvalidInput if annual_bet_frequency or target_sharpe is not finite and positive, or the payouts are not finite with pi_plus > pi_minus.
• StrategyRiskError::NoValidRoot if the quadratic has no real root, or no root in [0, 1] reaches the target.
