FFT Trading Sources... (fwd)

[simon32@xxxxxxxxxxxx]

I want to research FFT and DFT trading techniques more but am not sure where
to start.  Can anyone reccomend a good place to start or good book on the
subject.

A couple other questions are:

Are there places that sell tools using FFT/DFT for Tradestaion (not caned
systems).  Dennis Meyers has some systems but all his stuff is integrated
into systems that may or may not work (I am pessimistic about affordable
trading systems).  Tools that I could use to build my own system would be
better.

Thanks in advance.
