Imho of course, but if you build pricing models, in which there are clear deviations from the SB, then you can then, for example, on this basis, generate artificial quotes, even for a thousand years. Then on this quotation learn with the help of MO to determine those places where there were deviations, and then try to do the same on real quotations. Alternatively.
Average, subtract and divide :)
In general, as I understand, you propose to change the target on the section where the signal is "bad"?
That's what Alexei Nikolaev said.
Deviations from cb will do what? If it is another stochastic process, it is also random. Randomness doesn't end at the SB, it just begins.
Well, probably a search for market inefficiencies.
I meant whether there is such an approach in official science, as I have already heard exactly the same thoughts about the comparison with the SB
I wondered if there were any established techniques.
Here's a sketch.

At least yes, if you try to equalise through the model.
This may improve results in training, but not in application, if the first plot (with changed target) will appear more often on the history than the second one. But, I need to make the two plots equal so that the model separates them and switches between them, i.e. in theory there should be a categorical feature.

Well, you can make up a lot of things as you go along. Then something else will be added, and so on ad infinitum.
Of course - there's no limit to perfection!

Visually the graphs are similar.))
Heteroscedasticity is modelled in econometrics and all kinds of applied statistics. There are a lot of tests there. R should have them all. The problem is that they give an estimate of the past and it is not certain that it is suitable for the current moment.
