DSP is a huge area of digital information processing....
And you wrote about it in your own, very narrow sense of understanding
It's like writing that data science works with signals that are described by stationary......
To clarify... a signal is NOT a radiogram from an oscilloscope, but any information in digital form.
Stationary and quasi-stationary random processes. It is their realisations, from the point of view of mathematics, that are called signals. From a trader's point of view, it is an eternal flat, i.e. an eternal trader's paradise with trading on the return to the mean.
The difficulty in trading comes from the proximity of prices to the SB. The SB is NOT a signal. There is brown noise, it looks like a SB but it is NOT a SB.
I was looking at a couple of bourgeois bibles on COC. All of them at first write that "a signal is any sequence of numbers", but when it comes to mathematical specifics, it turns out that the signal is exactly what I wrote. For example, it is only for this case that you can define the ACF through convolution.
We should ban the topic, up to a month ban for mentioning it.
On weekends you can do a little) And from Monday ban)

If they would do it in their own thread without cluttering this one, there would be no questions. This also applies to you, by the way.

As soon as the presentation of the theory of signals becomes mathematically meaningful, stationarity (in the broad sense) and energy spectrum appear at once. And nonsense like "a signal is any set of numbers" obviously doesn't appear.
The article from the linked site attempts some sort of generalisation of the concept of stationarity. Regardless of how useful it is for DSP, it doesn't make much sense for prices. Once again, I will point out that stationarity of the price of an asset or the price of a portfolio of them is a trader's eternal paradise, because it means eternal flatness on which to trade forever, e.g. reversion to the mean.
This is the end of the discussion of COCs in this thread.
Nothing prevents you to start a new thread on DSP and discuss everything in it.
Here's a great example from.... by the way
