Form a synthetic index as a weighted average of 5 key stocks - take the difference of a target stock from the index, then view the ten day moving average of the result.
	Compute a moving average of bond prices, where the number of days over which to average varies (adapts) with the volatility.
	Select the last 20 days from a futures chart, and have a regression (best fit) line or polynomial curve automatically superimposed - or draw lines yourself on the chart. Then have those lines or curves automatically extended, and retrieve the predicted values.
	Compute an oscillator or price study, then smooth it with a nonlagged smoother for clearer signals.
	Form a smooth approximation of a dataset by retaining the 8 most dominant cycles of the Fourier transform, then apply moving average differences to the smoothed approximation.
	Compute the average standard deviation of one stock or indicator, then add that to the 25 day moving average of another stock to form a new type of "Bollinger Band".
	Do anything else that occurred to you - not because these are built-in menu items for FDC, but because of the natural, completely versatile, FDC environment.
	You say that your software could do some of these things, with the right combination of actions, saves, additions to lists, and so on, and you could hire a programmer to do other parts? You could also dig a ditch with a spoon - but why would you want to?
