Hi Dalla,

I think it depends on how well you know the underlying API.
I have years of experience with the Dukascopy API and so the development time took 2-3 weeks in total.
But consider that Dukascopy uses Java and not C/C++.
This makes the development hard, since you first need to write the JAVA<->C++ bridge with something like JNI.
If there would be only a C/C++ API, then of course the development time should be much shorter.

Cheers,
Juergen
