I am not very experienced with options. I have never seen option software other than something I programmed into my HP calculator to get greeks. So this question maybe very basic (excuse my ignorance).
I am wondering whether you can get a program that allow you to fiddle with the distribution. Can you get a black-scholes type elaboration of the greeks with an implied non normal distribution ?? Because what is the point of having an option pricing system that assumes normality when particular markets are obviously not distributed like this ?? Also is any of this software available for free ?
