Generate a standard dataset for evaluating indicators (compatible with MT4)

[MisterH]

Let's say you want to know how responsive your oscillator is to cyclic market movement, wouldn't it be great if some standard data set existed that consists of two parts:

first a cyclic part (e.g. a sine wave) with a constant dominant cycle length (e.g. 200 bars) and second a trending part.

Could someone generate this sort of dataset (in Matlab maybe?) in a format that it can be used in MT4?

I think it could make discussion of indicators more objective.

Let me know what you think.
