I'm looking for three indicator:

(1) Fourier Transforms http://mathworld.wolfram.com/FourierTransform.html http://en.wikipedia.org/wiki/Fourier_transforms

(2) Laplace Transforms http://mathworld.wolfram.com/LaplaceTransform.html http://en.wikipedia.org/wiki/Laplace_transform

(3) Z-Transforms http://mathworld.wolfram.com/Z-Transform.html http://en.wikipedia.org/wiki/Z-transform

this indicators base on math function, i shuold see plot of this transforms under the graph, please add mq4 file.

Yes, actually I do agree that it is a brilliant idea! Could anyone help solving this problem? I would like to wait for it...

...and what is this information actually going to tell you?
If you do a web search you will see that plenty of folks have already been down this path.

I know plenty of traders use Fourier transforms in trading (in fact, I actually have some code for it somewhere, but not for MT4). I'm sure all of these things can be coded. What is your system like?

Here is some link
fast Fourier Transform

If one consider the Price verse time as a wave. After transform it will gave peaks as frequencies, which will give us information about how long will take for each price peaks or bottoms will occur. All kind of filters can be used to filter out noise.
It is hard to plot the gragh on price chart since it has to display on peak verses 1/time graph.
There some other ways to use it. That is reverse transform the frequency peak back after some filters have been added. This will give us smoothed
price peak without delay (hopefully).
FourierTransform has been intensively used in the spectrometers field.
