In a university project I am looking at Black Scholes model with a stochastic volatility. I’m still not quite sure about my focus (I am in the beginning 'Idea phase'). I want to explain the theory behind stochastic differential equation and then implement some numerical methods too solve pricing models. I haven’t worked much with idea. Please make some suggestions/comments? How can I analyze some data from from the real world? I want to include simulations of real options prices or similar in my project. Thanks
