All Implemented Interfaces:

Cloneable, VolatilitySurface

public class CapletVolatilities
extends AbstractVolatilitySurface

A very simple container for Caplet volatilities. It performs piecewise constant interpolation (discretization) in maturity dimension on iso-moneyness lines and uses the default interpolation from the CurveFromInterpolationPoints class in strike dimension. It allows to convert from several quoting conventions. It needs a forward curve and a discount curve. The tenor length of the Caplet is inferred from the forward curve.

Version:

1.0

Author:

Christian Fries

To dos:

Need to add forward and discount curve to support implied vol.

forwardCurve - The underlying forward curve.

maturities - The vector of maturities of the quotes.

Method Details

getValue

public double getValue(double maturity,
 double strike,
 VolatilitySurface.QuotingConvention quotingConvention)

Description copied from interface: VolatilitySurface

Returns the price or implied volatility for the corresponding maturity and strike.

Parameters:

maturity - The option maturity for which the price or implied volatility is requested.

strike - The option strike for which the price or implied volatility is requested.

quotingConvention - The quoting convention to be used for the return value.

Returns:

The price or implied volatility depending on the quoting convention.

getValue

public double getValue(AnalyticModel model,
 double maturity,
 double strike,
 VolatilitySurface.QuotingConvention quotingConvention)

Description copied from interface: VolatilitySurface

Returns the price or implied volatility for the corresponding maturity and strike.

Parameters:

model - An analytic model providing a context. Some curves do not need this (may be null).

maturity - The option maturity for which the price or implied volatility is requested.

strike - The option strike for which the price or implied volatility is requested.

quotingConvention - The quoting convention to be used for the return value.

Returns:

The price or implied volatility depending on the quoting convention.
