In response to my message that I had previously perceived NLP in one sense only and did not correctly understand your reference to NLP, you suggested that I was confusing the concepts, so I did not understand this suggestion. I assumed that you were talking about NLP (neuro-linguistic programming ) before, so I hinted that I am not a telepath and cannot understand what you were talking about....
When was that? If your way of communication was something like that, then the first option of course.
So I understood everything correctly and reacted correctly :)
A fresh and kind of interesting article on MO and non-stationarity.
There is an interesting article about the power of bousting. But I haven't found the library of the same name yet.

Well, it basically comes down to choosing a market mode and adding macro indicators to the chips. The first one is definitely useful, with the second one you should experiment, because they do not change as often as you would like. For example, once a month statistics is released. Then it will be a different, news-based TS.
I was attracted by the very approach, when one tries to work with non-stationarity in a meaningful way, studying its structure.
Obviously, when studying non-stationarity in a meaningful way, one can't get far on technical features alone (based only on prices). But meaningful and useful addition of non-technical signs is not an easy matter.

Interesting but useless article. And the problem is that the approach to MO as a usual approach to statistics does not work.
I'll explain it with an example.
A few years ago I came across an article on garch, in which the choice of garch type (and there are more than 100 of them!) was made on prediction of all stocks included in S&P500. Everything is clear, statistics, you can use the results of the article and apply IGARCH more reasonably.
This does not work in MO.
It is not clear how the article tries to take into account some deviations, i.e. outliers.
At the level of preprocessing, the MO science suggests to somehow handle outliers, but the meaning of MO is lost behind these words: what are we teaching the model?
A seemingly simple question and a primitive answer.
However, it is far from it.
Some time ago, I brought to a demo account a TS with the teacher of price increment with classification error below 20%, or even 10%.
On the demo account I found out that this classification error corresponds to the ratio of losing and profitable trades.
It would seem that the profit factor should be about 4. But, no. Due to tricks in the Expert Advisor, I could not raise the profit factor above 1.5!
And here it became clear that my simple teacher taught the model to predict a profit of 10-15 pips, but was wrong on price movements over 50 pips.
For the last 1.5 years, I have been trying to construct a teacher (target variable) that would predict a profit multiple of a loss. But it turned out to be a very difficult task. I have to do a very intricate preprocessing of the teacher, then select a predictor for it, and it is extremely difficult to find predictors that are related to the teacher and not just noise..... All this in an overtraining and looking ahead environment - i.e., evaluation only on an external file with a step-by-step run...
Nothing like this in the article...
Sanych, a teacher is a person, not a target variable.
and you also deliberately emphasise your illiteracy by specifying"construct a teacher (target variable)".
