Forget random quotes - page 43

 

A very accurate addition to efficiency was made by Avals.

He pointed out that the market has grown because of investment. If not to trivialise it really is - the market has grown because of the growth of the economy. There is both completeness and awareness and equity in this area. And if there is no investment, is the efficient market white noise? Or a random wandering with drift? After all, it is argued that one cannot make money from it.

What regularities are used in trading, especially if we are talking about trend-following TS?

 
C-4:

I searched for information on first- and second-order errors and came across a doctors' forum. It is extremely interesting that the topic of discussion, strangely enough, is very similar to ours, but the level is much higher. Just look at the title of one of the topics:

Robustness and heteroscedasticity, How to get rid of emissions?

And they write about blood loss! If you read about it, you'll realize that without MathLab, R or Statistica you won't be able to be a good doctor!

Well, actually, a truth-telling doctor and a medical researcher are not the same thing (although sometimes they are combined in one person). For the sake of self-esteem, I will say that the percentage of professional medical statisticians who are good at matstat is not higher than that of professional traders, and the same is true of the population of the respective forums))
 
Mathemat:

So far the topicstarter in his calculations did not rise above the weak form of efficiency, i.e. did not use anything other than price data.

The funny thing is that no one has proved even the weakest form of efficiency even for the most technical instrument :)

I understand technicality as the ability to instantly assimilate all the information in the price(imho).

Alexei, you know that the mutual information on a number of quotes is non-zero, and that is a direct refutation of the efficiency hypothesis, as it comes out that the information is not reflected in the price instantaneously.

Well, the top starter put forward the thesis that if the market is manipulated, then there are trends there and you can make money from it. Oil, and financials are just the opposite. By the way, shares included in SP500 - the same thing, manipulated by hedgers, experienced traders (as far as I know) generally forbid newbies to get into it. Because they will tear the deposit to shreds.


In fact, the behaviour of hedgers is not obvious. As for the same oil, it is hard to find a correlation between their actions and the same oil price:

* The red line shows the dynamics of short hedgerow positions and the beige line shows the dynamics of long hedgerow positions.

 
alsu: the mutual information on a number of quotes is non-zero, which is a direct refutation of the efficiency hypothesis, since it appears that the information is not reflected in the price instantaneously.
Yes, of course. Even the weak form is refuted. But that's of almost no interest to anyone...
 
Mathemat:

interested. Only again the reason for non-zero mutual information is the dependence between the increments or just their modulus (volatility)? With conditional heteroskedasticity the mutual information is zero?

You can't prove that there is no efficiency (ability to earn), and you can't prove the opposite because efficiency changes.

For me, technicality is the ability to use techniques from TA in trading.

The hedgers on the sp500 were meant.

Also non-zero: the reason is not in non-uniformity of external influences (which is tracked by *ARCH handily), but in non-zero reaction time on influences + in presence of influences on different scales (for example, momentum on D1 when going to scale M1 can be well perceived as a quiet crawl in one direction)
 
Where did Auctioneer go... He's gone for half an hour and the topic's already gone :(
