# Does anyone have experience about Heston model's calibration?

Hello Every

Does anyone have experience about Heston model's calibration? I just followed nimalin moodley 's paper. But I can not get the same results as page 29. Did anyone do that before? Thanks a lot!

Ray

#### Andy Nguyen

The paper has matlab code at the end. Do you use those code to replicate the number ?

Hello Ray,

a friend of mine has compute a Heston-Calibration-program in C++.
But I do not know his experience with the nimalin moodley 's paper.

I ask him for further information.

But in the meantime here is a paper about Heston Calibration and a Matlab-Code:

Yes, I try that code. But I think that is not really correct. The main idea is correct but there are some problems. But I can not get the result in page 29 of that paper.

#### raywin

Thanks. I saw this code before in some web. Currently I just want to use mablab build-in function lsqnonlin to do calibration.

#### raywin

The idea is not really hard but there are some trivial work to do. I am researching that. Hope crack it asap!

Dear all,
I wonder whether it is logical to look at the term structure of the parameters in Heston model.
I mean do you think it is logical to calibrate Heston model to a spesific maturity on a spesific day(and doing this seperately for every maturity) and looking at evolution of the term structure of parameters by following the same procedure.
Your help will be very appreciated.

#### Andy Nguyen

Found this Excel code on Wilmott. You may find it useful.

Not sure if I understand well your question. You could use Heston with piecewise constant parameterization to calibrate a given smile surface.

what's your problem exactly? I haven't seen any result on page 29, except a graph of error calibration with no numerical output.

Calibration of Heston is quite tricky though. It's not as easy as in Moodley's. You should use Gauss-Lombarto and try to use Lipton-Lewis to save time of computation as you'll have to compute only 1 integral instead of 2.

Hope it helps.

You should use a global optimization technique (e.g. SA) to calibrate the model since you could end up in a local minima when using nonlinear least squares method. The optimization problem is not convex.

The Levenberg-Marquardt Method should also be recommendable.

does anyone have simple vba code for the heston model?

using fminsearch in Matlab will do the trick

I got good calibration results not only for Heston, but also for the more advanced Heston-Nandi (2000) model

#### Ahmed-amager

hey every one
.I am doing my master thesis in volatility forecating but I have a problem. I want to calibrate heston model as discribed in the following articles but I really cant find any thing (any code or help). I am trying hard but I am not good at programming so its tough. Maybe u or any body else on this site help me with the co de ? thanks in advance
