Renat Akhtyamov:
The market is financial. What kind of maths works here?
That's right, financial!
And no more.
What is the financial maths? The one where 2*2=5?
 
Uladzimir Izerski:

They don't let dolls of mathematicians andphysicists with bags to trade for money. Only poor baskakovs, crane operators, tyre fitters).

Rinat, do not give in to fleas, scratch. Show them a fresh picture, the past is outdated. Let them be jealous.

The month is not over.
 
PapaYozh:
What kind of financial maths is it? The one with 2*2=5 ?

Financial maths is like this. 2*2= -4;

Renat Akhtyamov:

Got it.

 
PapaYozh:
What is the financial maths? The one with 2*2=5?
2-2=0
And if 2 at so-and-so, another 2 at so-and-so, margin, point value, etc., then finances have already gone
So the question is - how do you make money?
We have coins, thinning, statistics, levels, forecasts and so on. What is it all for?
;)

 
Renat Akhtyamov:

And here - coins, thinning, statistics, levels, forecasts, etc. What is it all for?
;)

They want to get a statistical advantage, IMHO.
 
PapaYozh:

50 years of Fora.

It's high time you realised that it's all gone wrong, including the neurons.

They should behave like in a normal market, with a contingency and contingency plan of sorts.

It's high time we realised that all this doesn't work, including neuronics

The logistics task is absent as there is no immediate delivery and no distinct seasonality.

In the regular market, in most cases, simple and clear added value is created by solving logistics (delivery) issues from the manufacturer to the end customer or by abusing the elementary seasonality of the seasons. You buy in bulk, bring it to the shop, put it on display, stick your 10% and sell it. Bought in summer, froze it and sold it at a production shortfall in winter. Where is it all in the forex? There isn't. Pure speculation, this is a different story, there are no such simple schemes. There is no logistics, because supplies are instant and there is no pronounced seasonality.

In the regular market, most of the time, simple and clear added value is created through dealing with logistics (delivery) issues from the producer to the end customer or the elementary seasonality of the seasons is abused. You buy in bulk, bring it to the shop, put it on display, stick your 10% and sell it. Bought in summer, froze it and sold it at a production shortfall in winter. Where is it all in the forex? There isn't. Pure speculation, this is a different story, there are no such simple schemes. There is no logistical problem, because supplies are instant, there is no pronounced seasonality either.

Not everything is speculative. Oil, gas, timber, ore, machinery, aircraft, consumer goods and other things are bought and sold in large quantities. All that moves between countries, and the money is different in different countries. There are banks for that. They change them in the right quantities "by wire".

There is of course speculative capital, but it is not so significant. By the way it supports the liquidity in the forex market.

Too many contingency plans would be needed.
That's what Probability Theory is for. But you'll probably have to apply it in a completely non-trivial way...
 

There was a man called Oleg Verkhodanov. Talking about cosmology, he put it this way:

Есть утверждение, будто бы мир подстроен так, чтобы мы существовали. Например, воды на Земле столько, сколько нужно. Уберём воду - нас не будет, добавим больше - мы не сможем проэволюционировать до разумных существ. Как мы думаем. Мы же не знаем, как в реальности произойдёт. У нас ведь только одна выборка. А одна выборка даёт Байес, сдвиг в распределении. Если вы работаете с реальными данными, с реальным случайным процессом, то вы увидите, что неправильная оценка приведёт к совершенно другим выводам. А она будет связана всего лишь с тем, что вы неправильно оценили начальные параметры по конечности выборки из совокупности, которая бесконечна.

It's an interesting observation that characterises our field well. Let's think about it.
