Klaus,

 

I have checked the behavior of the Bates process within a MC engine I have done for different options.

I have compared the value of a 1M HSI vanilla call 90% strike with the market value and its Closed formula value after calibration.

You can see the results on the following graph:

 

It looks good to me.

I was wondering if it would not make sense in term of calculation speed to move the Normal distribution and Poisson distribution as part of the process it self? I know it does not make sense in term of abstraction, but having to create the object of each step could be coslty in term of speed.

 

What are your thougths?

Cheers

Hi

good point, I've just committed a BatesProcess class to the QuantLib CVS. See

http://quantlib.svn.sourceforge.net/viewvc/*checkout*/quantlib/trunk/QuantLib/ql/processes/batesprocess.cpp
http://quantlib.svn.sourceforge.net/viewvc/*checkout*/quantlib/trunk/QuantLib/ql/processes/batesprocess.hpp

Monte-Carlo Simulation works in the same way as for the HestonProcess (indeed
you might use the BatesProcess as a substitute for the HestonProcess). Please
see in test-suite/batesmodel.cpp

http://quantlib.svn.sourceforge.net/viewvc/*checkout*/quantlib/trunk/QuantLib/test-suite/batesmodel.cpp

the test case testAnalyticVsMCPricing().

hope that fulfills your needs

Klaus
