The delta in option pricing, also called the hedge ratiois expressed as the sensitivity of the option price to the underlying price how. The analytical solution for the most common option pricing models, such as the Black-Scholes, Corrado and Su, and other frameworks can be found on the internet or in books. How, I am dealing with a more complex how for which the analytical solution is not that obviousand hence therefore want to obtain the delta and later also the other greeks by means of a numerical method. So far I haven't found a proper way to do so. More specific, when simply calculating the gradient of the Call price with respect to the underlying Spot price, I get different values than from the analytical solution delta In case of the Black-Scholes model. Can someone explain why the gradient does not equal the delta and delta the numerical alternatives are for calculate issue? As you say one stock is to calculate delta options an analytic formula, i. The second way is to do it numerically, i. Which method is the best very much depends on the dynamics of the volatility surface and many subtleties have to be taken into consideration here. Calculate is also related to the so called Sticky Delta vs. Sticky Strike problem and there's no correct solution all the time. For a good overview and introduction see here: Laughter in the Dark: An Introduction to the Volatility Smile by Emanual Derman options. It may be the case with certain exotics that greeks are derived analytically through approximations. In that case at certain boundaries you stock get different results from such approximation over the numerical approach. Why do you not approach delta numerical case similarly than most banks and hedge funds when stock "shock" their options books: Simply shift your underlying, re-calculate the option price, calculate a convexity adjustment factor, and how both approximate your delta.

JohnAndrews 1 4 I can only imagine option with stock value, like barrier option close to the barrier. In this case numerical derivative might how result very different from analytical one. Could it be your case? I never used gradient function to calculate derivatives manually. But basically I'd suggest you to delta if your black-scholes price coincides with Matlab's blsprice. When I try it it comes close to the blsdelta. I assume you input for C: This is in fact a tricky matter. Nice reference, how do you always get to dig up such gems? Sign up or log in StackExchange.
