This training course includes the Matlab source code for computing vanilla and barrier option prices, together with their Greeks, under the Heston model. The numerical solution technique is based on a suitable finite difference discretization on nonuniform spatial grids followed by a state-of-the-art ADI time discretization scheme.

  • Heston PDE for vanilla and barrier option prices
  • Initial and boundary conditions
  • Specific issues: mixed derivative, Feller condition
  • Domain truncation
  • Nonuniform spatial grids
  • Spatial discretization: finite difference (FD) schemes
  • Temporal discretization: four state-of-the-art ADI schemes
  • Linear systems: LU factorization
  • Stability and convergence analysis
  • Specific issues: damping procedure, cell averaging
  • Step-by-step discussion of the HestonADI code (Matlab)
  • Numerical experiments
  • Approximation of the Greeks
