Well Matt what are you waiting for... priorities?
Ahhh just kidding
 
Matt Hi, I am not a programmer but I am interested... When one says " NEURAL ANALYSIS " what are we talking about. Relative to just pure analysis or TA of a stock how does this possibly differ. When googleing the term I get all the new Software and no real definition as to what the term means.
Soooo in your words....
 
 
Thanks,

This code is not AFL - it is C code, and the header files are C headers
(with the exception of iostream, which is a C++ header). The only way
you will get this to work is by using a C compiler (Microsoft Visual C++
or GNU C are most common, both which can be had for free -
http://www.microsoft.com/express/vc/).

I have written a neural net plugin for AB based on the well regarded
FANN library which I was planning on atleast partially releasing, but
time constraints on me from my day job and having higher priorities on
my family have retarded the polishing and release process...

Matt
