Ilnur, only casinos are guessing, but I agree

When dealing with bees, nothing can be said in advance. (c) The market is random - either we guess or we don't.) I've shown before that it makes absolutely no difference whether it's actually random or completely deterministic.

What are you stabbing)))). What, what-what. You don't have a job, simple or complex. The slightest scratch, it starts, well-I knew it, I agree. Sectarians. One does not understand what he himself said, the other does not understand what he fantasizes about what he said.

right, i agree ! i used to know that.

The point was that the guessing game is not the way to go

There is no other way. Only guessing. The only question is the methodology of guessing.

 
Yuriy Asaulenko:

There is no other way. Only guessing. It's just a matter of guessing methodology.

Well, I don't know, then.

After writing a bunch of systems, I'll say this.

In the last one, I added two AIs and realized they got in the way.

I don't remember why.

 
ILNUR777:
Oh, man. Well, if they don't guess, let them predict. That wasn't the point. You don't care if it's a prediction or a guessing game. Heh-heh-heh.

the forecast is better, you can say afterwards - the forecast was wrong.

You can't say you didn't get it right, can you?

 
Yuriy Asaulenko:

Let's start with the black box - we don't know what's going on inside it. What - "reflect the processes going on inside the object" can we talk about? And the question about the accuracy of the description of the processes inside the object is wrong. A model of the BS is not meant to describe processes inside the BS at all. The model must describe the behaviour of the system as a whole.

The requirement of simplicity just gives viability, and the complication gives excellent convergence only in the model development section. You can show this on simple regression models, where simple describes the process more adequately.

Yes, and simplicity should not be confused with primitiveness.

You don't know. But you can adequately model it. If you want to) And in general, I just made a logical test of the statement - the more complex the system, the simpler the model. Two opposing vectors. In the limit you get complete absurdity.

To paraphrase O.Bender - I know 100 relatively honest ways to use MAs). MAs are a very good indicator. It all depends on what to use them for. It's true, I haven't been using them for the last seven years, though I don't use any of the "standard" ones either. It all started with https://www.mql5.com/ru/code/8538 but I haven't used it for about seven years either.)

Представляет собой стандартный индикатор MovingAverage с добавленной функцией сглаживания фильтром Баттерворта 2-го порядка. Сбалансирован так, чтобы при выборе одинаковых периодов сглаживания, вес текущего отсчета соответствовал весу в Exponential Moving Average. Для выбора сглаживания по Баттерворту выбрать MA_Method=4.

I wanted to get into the market more accurately, at least a bit. Then I got MAs in the last TS.

And then it turned out that I couldn't do it at all. Loss is inevitable.

I started without any indices at all, but then I liked them. I wrote quite a few of them too.

They're drying up in the wastebasket now.

Perhaps I didn't phrase it quite right. There is no need to take it to the point of absurdity. In principle, almost any formulation can be taken to the point of absurdity.

We can formulate it differently. Say, there is a certain limit of complexity of system description, after which increase of complexity leads to deterioration of system description quality. It is possible to specify for a long time, but within the framework of the topic it will be infinite.
