FAST FOURIER TRANSFORM
The recent article “Fast Fourier Transform” by Amy Wu in the July 2002 STOCKS & COMMODITIES was an informative article. The last two sentences stated: “...many aspects, such as phase, are being discounted to fit the type of data in use. [I agree.] Still, interpreted correctly, FFT can greatly enhance your accuracy on other more fitted indicators.”
We need a followup article telling us what these other indicators are — such as stochastics, MACD, RSI and others — and how to select the best parameters for them using the FFT results.
