Blaine, from my math class I know that there is a possibility to approximate more or less any curve by a method called "Fourier synthesis". It is basically puting together several sine functions in order to make up a given curve or function. In this case "curve fitting" is the aim. But if you optimize a formula containing several parameters against a given stock, you end up with good signals for the period used for optimization only. Outside the sample data the system usually does not work. A systematic way to reach a system, that works outside the sample, I do not know. Thats, what I consider the ugly truth. Wolfgang
