But if you have received something, you must know what you have received? So you must know the algorithm roughly? Shouldn't you?
 
C-4:
But if you received something, you must know what you received? The algorithm must be known to you? Isn't it so?

So far, only an algorithm for approximating pieces of an unsteady process has been presented.

Mathematically, there is nothing you can do about it initially... All that is left is guessing with this on coffee grounds, hoping "at random"...

All that remains is to draw a suitable Expert Advisor that must be profitable because it is guaranteed to be inadequate. :)

No, if we are talking about the algorithm of a trading system, it's not so. It's the process of searching for the algorithm.

This is the picture I got.


What does the blue (thickened) line mean, and what is the yellow line?

Yellow is the final approximation, blue is the older trend.
 
Candid:
Yellow is the final approximation, blue is the older trend.
Why is the older trend going down? You can see from the figure that it should be up.
 
Candid:
Yellow is the final approximation, blue is the senior trend.

Here, the yellow one looks like an adequate line. Based on my understanding of the bazaar's process of taking money from the peeps. And the blue one is either not drawn as it should be, or the trend is from a much larger area.

This cannot be seen from this figure because it is calculated over an interval somewhat larger than the figure.

The yellow line is the sum of C0 + C1*t + C2*Sin(t) + C3*Cos(t), the blue line is C0 + C1*t.

That looks a lot like a mashka. :) It's not worth the trouble of reinventing the velocipede.

This cannot be seen from this figure because it is calculated on an interval that is slightly larger than the size of the figure.

The yellow line is the sum of C0 + C1*t + C2*Sin(t) + C3*Cos(t), the blue line is C0 + C1*t.

So, yes,

it looks like a trend from a larger interval.
