Enhancing finite difference approximations for double barrier options: mesh optimization and repeated Richardson extrapolation

Luca Vincenzo Ballestra
2021 Computational Management Science  
AbstractWe show that the performances of the finite difference method for double barrier option pricing can be strongly enhanced by applying both a repeated Richardson extrapolation technique and a mesh  ...  Then, a finite difference scheme employing repeated Richardson extrapolation in both space and time is developed.  ...  Then, we apply a finite difference scheme enhanced by repeated Richardson extrapolation in both space and time.  ...
