Well, from that position, of course it's stupid.

Well, we've been dumb for two days without reading the definitions.

And I'm from the position of signal definition

It turns out there's some guy sitting on the other side sending you messages via stock quotes, which you filter to decipher it. Stupid? Yeah, it is.

That's bullshit. I read the definitions in the book.

That's bullshit, I've read the definitions in the book.

The added irony is that the information in a signal, even if there is any, does not necessarily tell you the future of that signal.

And you're confusing a signal with waves, which have amplitude, etc. They are the carrier of the signal and may carry nothing at all. If you decompose a graph into waves, you can't read a signal about the future of the system. Because you don't have a clue, even if the quotes hypothetically carried the signal.

I gave the definition of a signal, I certainly never confused it with waves

No, you're just extrapolating waves (aka components of a time series), judging by the pictures. It doesn't work if there is no seasonality and other cycles. There's no signal at all.

depending on which pictures you're talking about.

Interesting thought...

What if we create a sample data generator that will come up with new data rows and add them to the sample. Add such samples that will cause the error to fall off
