Hi Luigi and the rest,
Thanks a lot for showing us such a clear picture about future 1.0 release!
I just have one addition:
- modify the interfaces of finite difference pricing engines (like
FDEuropeanEngine class) so that users can specifiy different solver
(Explicit, Implicit or Crank-Nicolson) and different asset price
range. Currently the solver is fixed to Crank-Nicolson.
Does this change make sense to you? and any advice?
Cheers,
Max
