Detailed Description
Base class for FFT pricing engines for European vanilla options.
The FFT engine calculates the values of all options with the same expiry at the same time. For that reason it is very inefficient to price options individually. When using this engine you should collect all the options you wish to price in a list and call the engine's precalculate method before calling the NPV method of the option.
