A simple mashup and a curvilinear segment based on the midpoints of a linear MNC are the same thing.
Who uses MNCs there?
An ISC is, after all, taken over several points, not every two points a different segment... Not to mention that MNCs can be taken to a higher degree - second or third.
Well, that's what modelling is for, not to write a PBX straight away.
I modelled my previous PBX for about six months. It ended up being a very simple and beautiful system. But in the process it was more than enough complications).
Here is almost no visualization. All logs are written in an Access database.
I would like to agree, but ... But I want to argue ... ))
you need to formalize the task, on elementary (terribly simple!) tasks:
- the result of writing an ATC is what - to get a balance chart!
- ideally, we want a balance line at 45 degrees upwards, to aim for such a line, we need to know
a) the forecast of the movement
b) the reliability of the forecast
i.e. by deep reasoning, we arrive at the video:https://www.mql5.com/ru/forum/221552/page525#comment_8564120
task a) : what do we need to predict? we need a price movement pattern:
- trends = line
- channels = 2 lines
- levels = ??? but I want to predict this, I suspect that it is a few horizontal lines which will change their values depending on the time of holding the position in the market
task b) is solved by the strategy tester and statistical observations
that's about it, the minimum left to do is to deal with task a)

Rejected:
- the model of price movement (better to say, almost rejected),
- I gave up forecasting (almost too). Everything comes from statistics and probabilities. I.e. losing trades are already an initial property of the system.
- I have given up optimizing for maximum profit. As a result we get a lot of different criteria, but all subsystems are set up mainly separately (independently).
well I'm using polynomial, so it's "different parts of a parabola".
You could also try using an arc, but I don't know how to do a regression on it.
Can you derive the arc equation from here to score it in excel?

Thanks for the link, got carried away looking for related ideas. I don't think you need to approach the question as there, from the perspective of R-functions. Approach with conventional means:
Directly from the equation of a circle of radius R with centre coordinates Xc, Yc, ignoring the loss of meaning in units (number, course, distance)
R^2 = (X-Xc)^2 + (Y-Yc)^2
we make a function of the inconsistency at the point with the number i (Xi = i). This is the difference between the distance from point (Xi, Yi) to centre Xc, Yc and radius R:
Di = ((Xi-Xc)^2 + (Yi-Yc)^2)^0.5 - R.
The squares of Di and add up to obtain the target function to be minimized. There are three parameters to be varied: R, Xc, Yc. At extreme (first and last) points the influence is less than at intermediate points (no adjacent), I think it is better to multiply corresponding Di^2 by two. And for your fitting purposes with emphasis on the last points, you can also play with weights of several last points by setting up one more column for weights.
If it is not straight, the units of measurement will have to be taken into account. In order to make X and Y influence almost equal in distance calculation (and R is affected by both), it's necessary to take as X not i number, but the same number multiplied by alignment scale, so that X and Y ranges are close in size.
P.S. It turns out that sernam.ru has very cleverly got rid of the accusations of copyright infringement by publishing the texts of books only in parts and without specifying the output data, in particular the titles of the books. It is possible to find texts on sernam.ru which can be found nowhere else on the internet.
I like to work on small TFs, but I don't like these snafus.
How do you predict them?

Why "predict" them - they need to be "handled" correctly! There is nothing special about them, they need to be "detected" in time and properly "handled".

Detecting is always too late. But predicting is just that.
Determining is always too late. And predicting is just that.
If predicted verbatim, then yes, no problem, anything. But justifiably, that's unlikely. "Determine" is not always to be late, on the contrary, it is more to be "ahead"!
