secret:
1. It is possible, it is a stationary series.
2. Impossible, and that follows from the definition, you don't even need proof here.
3. The real model of price BP is unknown to us, so there is no way to prove theoretically the impossibility of earning on prices.

As for the second point, random profit/loss is possible) But it is impossible to create a model for earning by definition of SB. There is nothing to stick to)

OK.

Next question:

- why is so much attention and debate in this thread referring specifically to SB if"the price VR model is unknown to us"?

I quite agree.

Good.

It is possible that once discovered and proven that the price series has features of SB) The model as a whole is not known, it is of course possible to identify quite stationary areas and for them find a model with sufficient accuracy, but the moments of entry and exit in such areas cannot be determined / too difficult / costly without measure )

The model as a whole is not known, it is of course possible to identify sufficiently stationary areas and find a model with sufficient accuracy, but it is impossible / too difficult / costly to determine the entry and exit points of such areas without a measure).

So we are talking about stationary blocks of price increments? After all, the general consensus is that they are the ones you can and should make money on? Isn't it?

So:

1. The price itself may not be considered as its model is not known to us and is maximally approximated to the SB and, by definition, it is impossible to make profit on it.

2. We may make profit on stationary segments of price increase.

Right?

 
What is a stationary price increment plot?
 
Evgeniy Chumakov:
What is a stationary price increment plot?

On which the MO and dispersion are constant.

 
Valeriy Yastremskiy:

Casual is possible of course. We are talking about the possibility of earning all the time.
 
Alexander_K2:

Good.

Next question:

- why is so much attention and debate in this thread referring specifically to SB if"the price range model is unknown to us"?

Yes, because "SB earnings" is a quick and easy test to identify characters who are not good at maths.
The price range model can and should be discussed, but without these sectarians provoking pointless arguments.
 
Went in, saw the initials of some Sergei Borisovich and Matrena Olegovna again, realised it was all gone, went out
