Take two different parabolas, for example. There is a linear relationship between them. Although both curves are non-linear.In order to make the relation become linear, the coordinates must be transformed non-linearly. I will not talk about some data, but for the problem of estimating the probability of large deviations I enclose a book-sized article: Wentzel A.D. Rough limit theorems on large deviations for Markov random processes. Hardly read it myself, but it may help you. The 1976 edition.
You have to transform the coordinates non-linearly to make the relationship linear.
As you all know ANY problem can be solved in SEVERAL DIFFERENT ways...
For example:
1. You can try to PREVENT a FUTURE trend reversal...
2. You may document a trend reversal in a CURRENT situation in the market...
As you understand, variant №1 is VERY difficult to solve with a high degree of reliability...
Option #2 is much easier, as you don't have to be a psychic like Vanga, and the positive results will be much higher than in the first option...
All in all: The RIGHT way of setting the problem gives more than half of its solution!
For the relation to become linear, the coordinates must be transformed non-linearly. I will not talk about some data, but for the problem of estimating the probability of large deviations I enclose a book-sized article: Wentzel A.D. Rough limit theorems on large deviations for Markov random processes. Almost haven't read it myself, but it may help you. The work is from 1974.
I think Elena Sergeevna was.
It's not about trends at all

Guys, thick tails are just a confirmation of TV's unsuitability for trading. They're very thick. Thicker than the top.
and TV, too.
but I read about the Cauchy distribution yesterday.
There's a funny thing about probability densities.
and sincethe probability of entry is 0.5, therefore the probability density function should be equal too
In this case we are no longer interested in the shape of the distribution, and by and large the theorist has already done his part ;)
here's a drawing from a parallel thread

There's a lot of those around here. Not even molecules left...
if you calculate the area of the triangles for buy and for sell, they are not equal
i.e. this kind of theanalysis is doomed to fail.

In this case the theory underlying the Kolmogorov-Smirnov test would be more accurate. The empirical distribution function is treated as a Poisson process and its deviation from the theoretical distribution function in the limit (when the sample size tends to infinity) will converge to a Brownian bridge. You can read it in Borovkov's textbook on matstat.
