I was wondering if anyone has come across a more straightforward derivation of the semi-closed form solution for the price of a european call under the Heston model than the one proposed by Heston (1993) ?

  • $\begingroup$ You mean the maths is too hard? There're lots of books that covers the same topic. $\endgroup$

  • $\begingroup$ There are two steps here: (1) derivation of the c.f. for the log-price, and (2) inversion of the c.f. to recover the option price. Which step is troubling you? $\endgroup$

I cannot guarantee that it is error-free, but this paper (appendix A) has a relatively straightforward derivation of the Heston price for a european call.

I try to give what I at any rate think is a clear explanation of the Fourier transform approach to option pricing for various models including Heston in More Mathematical Finance.

You could also try Lewis's book Option Valuation Under Stochastic Volatility.
