This paper proposes a novel approach to pricing of American put option under double Heston model. We develop an analytical solution to the double Heston partial differential equation (double Heston PDE) using the equivalent European put option price and standard portfolio-consumption model.

In Chapter 3, we extend the decomposition formula for option prices in Heston model by Al`os (2012) [1] to a general stochastic volatility model. We then apply it

volatility models, the Heston Model's volatility stochastic process. The implementation is inclusive of random-number generation in a Monte Carlo engine. Monte Carlo simulation is a vital technique used in option pricing as it not only provides an improvement in the efficiency of

In a martingale, the present value of a financial derivative is equal to the expected future valueofthatderivative,discountedbytherisk-freeinterestrate. 2.1 The Heston Model… optByHestonNI uses numerical integration to compute option prices and then to plot an option price surface.

Using the equation, Heston came up with the price for a European call option as follows $$ C_T=e^{-r(T-t)}\int_0^∞dx(e^x-K)+ρ(x) $$ Here x = log(S) and p(x) is the probability density function of the underlying asset’s price.

Define Option Variables and Heston Model Parameters AssetPrice = 80; Rate = 0.03; DividendYield = 0.02; OptSpec = 'call' ; V0 = 0.04; ThetaV = 0.05; Kappa = 1.0; SigmaV = 0.2; RhoSV = -0.7; Option strike price value, specified as a NINST-by-1, NRows-by-1, NRows-by-NColumns vector of strike prices. If this input is an empty array ([]), option prices are computed on the entire FFT (or FRFT) strike grid, which is determined as exp(log-strike grid).Each column of the log-strike grid has 'NumFFT' points with 'LogStrikeStep' spacing that are roughly centered around each element of log 1 Heston's Stochastic Volatility Model 5 1.1 Introduction 5 1.2 Option Pricing in the Heston Model 6 1.2.1 Partial Differential Equation for a Contingent Claim 6 1.2.2 Risk-nevitral Pricing with respect to A 8 1.2.3 Numerical Pricing Methods versus (Semi-) Analytical Pricing Formulas . 10 2 Numerical Simulation Methods 15 2.1 Exact Simulation Scheme 15 What is the formula for the vanilla option (Call/Put) price in the Heston model?

This work presents an efficient computational framework for pricing a general class of exotic and vanilla options under a versatile stochastic volatility model. We propose a finite state continuous time Markov chain (CTMC) model which approximates the classic Heston model.
