Class OptionSurfaceData

java.lang.Object

net.finmath.marketdata.model.volatilities.OptionSurfaceData

public class OptionSurfaceData
extends Object

An option quote surface with the ability to query option quotes for different strikes and maturities. The surface is constructed as a collection of smiles. The choice of this dimension is convenient in view of calibration via FFT methods. This class does not perform any interpolation of market quotes. It merely represents a container of information. The class provides also the ability to perform the conversion among different quoting conventions and hence can be used both for a calibration on prices or implied volatilities. The class currently does not cover normal volatilities. Lognormal volatilities are more common in the equity space. The extension is not problematic.

OptionSurfaceData

public OptionSurfaceData(String underlying,
 LocalDate referenceDate,
 double[] strikes,
 double[] maturities,
 double[][] values,
 VolatilitySurface.QuotingConvention convention,
 DiscountCurve discountCurve,
 DiscountCurve equityForwardCurve)

This is a very restrictive constructor that assumes that for each maturity we have the same number of option quotes.

Parameters:

underlying - The name of the underlying of this surface.

referenceDate - The reference date for this market data (t=0).

strikes - The vector of strikes.

maturities - The vector of maturities.

values - The matrix of values per (strike, maturity)

convention - The quoting convention (@see net.finmath.marketdata.model.volatilities.VolatilitySurfaceInterface.QuotingConvention).

discountCurve - A discount curve for discounting (funding/collateral rate).

equityForwardCurve - A the discount curve for forwarding (repo rate (e.g. funding minus dividents).

OptionSurfaceData

public OptionSurfaceData(OptionSmileData[] smiles,
 DiscountCurve discountCurve,
 DiscountCurve equityForwardCurve)

Creates an equity option surface from an array of smiles.

Parameters:

smiles - The option smile data.

discountCurve - A discount curve for discounting (funding/collateral rate).

equityForwardCurve - A the discount curve for forwarding (repo rate (e.g. funding minus dividents).
