Greeks with continuous adjoints: fast to code, fast to run
The continuous adjoint method for computing risk figures of options that can be priced with partial differential equations is elegant, flexible and robust. It can be implemented in legacy codes with minimal code modifications and in particular without using tools such as automatic differentiation. Numerical results on the production environment for foreign exchange options using a local stochastic volatility model show important speed improvements. The authors report their experience of analysing and implementing this technique
