In order to do that, we start by constructing the Heston model with some dummy starting parameters as shown below.

Motivation calibrated parameters: unstable and often unreasonable emergence of market data for vol derivatives ) x beforehand v By Rekhit Pachanekar. The Heston option pricing model is supposed to be an improvement to the Black-Scholes model which had taken some assumptions which did not reflect the real world.

The Black-Scholes volatility surfaces generated by Heston’s model look like empirical implied volatility surfaces. Heston model as a local structural model, applying only within a trading day. The only restriction we impose is that the parameters are the same for all of the trading days in the pool.

### Now we model the full Heston model, which is (16) (dX t = X t dt+ p v tX tdWX dv t = ( v t)dt+ ˘ p v tdWv Here, X t is the price of the stock and v t is its volatility. To simplify the calculations, we will drop the drift term in the stock price equation, since this term will not a ect the shape of our solution, but will merely shift it.

Therefore, the model of choice is the Heston model because it has a semi-analytical Fourier solution for option prices and hence derivative pricing is relatively cheap. Chapter 3 The Heston model is an extension of the Black-Scholes model, where the volatility (square root of variance) is no longer assumed to be constant, and the variance now follows a stochastic (CIR) process. This allows modeling the implied volatility smiles observed in the market. The stochastic differential equation is: The stochastic volatility models have been widely studied in literature and one important ap-proach consists of the Heston model [29] and its extensions. In the standard Heston model, the instantaneous variance is a square-root mean-reverting CIR (Cox-Ingersoll-Ross [11]) process.

Fiorentini G., Leo« A. and Rubio G. (2002) [7] introduce a two-step estimation models with features that are consistent with market data. Many stochastic volatility models generate, more or less, the same (implied volatility) surface. Therefore, the model of choice is the Heston model because it has a semi-analytical Fourier solution for option prices and hence derivative pricing is relatively cheap. Chapter 3 The Heston model is an extension of the Black-Scholes model, where the volatility (square root of variance) is no longer assumed to be constant, and the variance now follows a stochastic (CIR) process.
