public class DigitalOption
extends AbstractFourierTransformProduct

Implements valuation of a European option on a single asset. Given a model for an asset S, the European option with strike K, maturity T pays
indicator(S(T) - K) in T
The class implements the characteristic function of the call option payoff, i.e., its Fourier transform.

Constructor Detail

DigitalOption

public DigitalOption(double maturity,
                     double strike)

Construct a product representing an European option on an asset S (where S the asset with index 0 from the model - single asset case).

Parameters:

maturity - The maturity T in the option payoff max(S(T)-K,0)

strike - The strike K in the option payoff max(S(T)-K,0).
