Detailed Description

Black 1976 calculator class.

Bug

When the variance is null, division by zero occur during the calculation of delta, delta forward, gamma, gamma forward, rho, dividend rho, vega, and strike sensitivity.

Examples:

DiscreteHedging.cpp.

Member Function Documentation

Real deltaForward () const

Sensitivity to change in the underlying forward price.

virtual Real delta (Real spot) const [virtual]

Sensitivity to change in the underlying spot price.

Real elasticityForward () const

Sensitivity in percent to a percent change in the underlying forward price.

virtual Real elasticity (Real spot) const [virtual]

Sensitivity in percent to a percent change in the underlying spot price.

Real gammaForward () const

Second order derivative with respect to change in the underlying forward price.

virtual Real gamma (Real spot) const [virtual]

Second order derivative with respect to change in the underlying spot price.

virtual Real theta (Real spot, Time maturity) const [virtual]

Sensitivity to time to maturity.

virtual Real thetaPerDay (Real spot, Time maturity) const [virtual]

Sensitivity to time to maturity per day, assuming 365 day per year.

Real vega (Time maturity) const

Sensitivity to volatility.

Real rho (Time maturity) const

Sensitivity to discounting rate.

Real dividendRho (Time maturity) const

Sensitivity to dividend/growth rate.

Real itmCashProbability () const

Probability of being in the money in the bond martingale measure, i.e. N(d2). It is a risk-neutral probability, not the real world one.

Real itmAssetProbability () const

Probability of being in the money in the asset martingale measure, i.e. N(d1). It is a risk-neutral probability, not the real world one.

Real strikeSensitivity () const

Sensitivity to strike.
