One of my acquaintances, Vasya Yakimkim, known as an advanced trader , told me about these attractors twenty years ago. Then he wrote a book " Forex : How to Make Big Money " and even became a government advisor on relevant investments in some institute under the President. So this Vasya did not mention attractors in his book, apparently disappointed in the prospects of this approach. However, these are my assumptions.
There is a rather old book by Peters "Chaos and Order in Capital Markets". In it, if I am not confused, he considered an attractor for some prices. The dimensionality of the attractor turned out to be quite large, which leads to doubts about the statistical significance of the result (practical usefulness is out of the question).
What is it? Is there a new rising star on the horizon, Yusuf 2?
Not just S square, but modulus S, and only then square..... What amazing scientific subtlety.
...and not a line of code.
The picture is beautiful, and especially impressive is the depth of the meaning embedded in it - the orange stripe in the upper left corner - you can't argue with that - the probability of price hitting the past is minimal.

Complex numbers? No, I don't know.)
Physics doesn't study the psyche. By your logic, the psyche is not real? Or should it not be considered at all? And you consider yourself just a body, a body?
Objectively, your real psyche is in your head and only in your head. It (your psyche) does not exist anywhere else in reality. Your psyche, having read the scholasticism of Hegel, Lenin and others, accepts some concepts (sets of words from other people's psyches) as a picture of the real world. This is your choice. These concepts (subjective sets of words), except for "Believe me", are not objectively confirmed by anything. In such a case it is strange to apply these concepts to the market. However, it is known from trading literature that there were traders who successfully traded according to the phases of the moon. There was also a high positive correlation between the market direction and the results of the NBA championship. Probably this can be adapted to trading as well)
Complex numbers? Nah, I don't know)
Of course not, how come... tell me.
Ask about the multiplication table.
You must have had a very hard time with complex numbers, hence such suspiciousness? Are you sure you understand complex numbers correctly?
Wikipedia: Mathematical expectation is a concept inprobability theory, meaning theaverage ( weighted by the probabilities of possible values) value ofa random variable.
Share the secret of how to determine the averaging period and channel width, it is such a trifle for you.
1. Wikipedia has it right. But you will never know this average value. In practice, they operate with the expectation estimate of the NE, which in matstatistics is simply called the mean.
2.It is not a trifle, it is the subject of research, which is what I am working on now. As for the formulas, google "Unravelling Problem")
This is true only under certain conditions (independence and equal distribution, for example), which are obviously not fulfilled for real prices.
I agree with the clarifications. But for lack of better forecasts, we accept the average forecast)

Why then is it common to use the term "expectation". I think everyone knows that we say one thing and mean another
Then why do we use the term "expectation"? I think everyone knows that we say one thing and mean another.
It is accepted in the environment, where something vaguely heard about probability theory, but do not know that matstatistics is a separate direction in mathematics for the study of empirical data. Of course, matstatistics is based on probability theory, but it has its own methods. Probability theory studies exclusively the laws of distribution of random variables, which are imaginary entities)

So in probability theory it is appropriate to say "expectation", and in statistics "mean", and it is undesirable to confuse them, otherwise it becomes bad for specialists from this field? Right?
