Inheritance diagram for BlackVarianceCurve:
Detailed Description
Black volatility curve modelled as variance curve.This class calculates time-dependent Black volatilities using as input a vector of (ATM) Black volatilities observed in the market.
The calculation is performed interpolating on the variance curve. Linear interpolation is used as default; this can be changed by the setInterpolation() method.
For strike dependence, see BlackVarianceSurface.
- Todo:
- check time extrapolation

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes. Implements Observer. |
