Hi Ford -- The length of the FFT lookback is so large that it does not have much value when used with financial time series.
There are some other algorithms that attempt to compute the periods of dominant cycles. Search for John Ehlers in the AmiBroker forum postings and library (or read his books) for one idea. Some people like the (proprietary) work of Mark Jurik, for another. Other suggestions?
