In this paper, by introducing of the double Heston's stochastic volatility model, since the prices of underlying asset in the financial markets are subject to the abrupt changes caused by different factors, by adding jump term to the double Heston model, we propose a new financial model, called the double Heston's stochastic volatility model with jumps. Then, by determining the characteristic function of the underlying stock price process, we obtain a formula for the European call option pricing under the proposed model by using the Fast Fourier transform method. Due to existence the jump term in the stock price process, the proposed model can be widely used in the financial markets, such as oil, gold and stock financial markets. Therefore, the model is more flexible than the Heston model and covers the abrupt changes of underlying asset price. The main goal of this paper is to present the model and derive a numerical scheme for the European option pricing.
