this would be very much appreciated! I've been thinking about tackling
the last issue it's long time now, but never had the occasion.
BTW I've noticed that an algorithm is provided in the last version of
Haug Fomulas book, anyway i don't know if it is the most efficient
algorithm available

As for premium adjusted black scholes deltas I'm not familiar with FX,
but just go ahead and document the features.

And while there, anyone willing to provide Vanna-Volga interpolation?
