Constructors
See the TermStructure documentation for issues regarding constructors.


BlackVolTermStructure (const Calendar &cal=Calendar(), BusinessDayConvention bdc=Following, const DayCounter &dc=DayCounter())
default constructor
BlackVolTermStructure (const Date &referenceDate, const Calendar &cal=Calendar(), BusinessDayConvention bdc=Following, const DayCounter &dc=DayCounter())
initialize with a fixed reference date
BlackVolTermStructure (Natural settlementDays, const Calendar &, BusinessDayConvention bdc=Following, const DayCounter &dc=DayCounter())
calculate the reference date based on the global evaluation date

forward (at-the-money) volatility
Volatility blackForwardVol (Time time1, Time time2, Real strike, bool extrapolate=false) const
forward (at-the-money) volatility
Real blackForwardVariance (const Date &date1, const Date &date2, Real strike, bool extrapolate=false) const
forward (at-the-money) variance

Calculations
These methods must be implemented in derived classes to perform the actual volatility calculations. When they are called, range check has already been performed; therefore, they must assume that extrapolation is required.


virtual Real blackVarianceImpl (Time t, Real strike) const =0
Black variance calculation.
virtual Volatility blackVolImpl (Time t, Real strike) const =0
Black volatility calculation.

Detailed Description

Black-volatility term structure.

This abstract class defines the interface of concrete Black-volatility term structures which will be derived from this one.

Volatilities are assumed to be expressed on an annual basis.

Constructor & Destructor Documentation

BlackVolTermStructure (const Calendar & cal = Calendar(), BusinessDayConvention bdc = Following, const DayCounter & dc = DayCounter())

default constructor

Warning

term structures initialized by means of this constructor must manage their own reference date by overriding the referenceDate() method.
