onava;
An essay could be written on a vey elegant level to explain how everything about markets melds together to provide for all the needs of any trader to be able to continually extract the offer of the markets.
So yes, anything one can observe contributes value to a full, continuing and elegant solution for extracting the offer as it is made.
The dynamic equilibrium will always provide anything you need or want to know about markets. The beauty of it all is that anyone can participate as he pleases and the market is always right, has no noise and no anomalies exist, ever.
Fortunately, Nature provides abundant complete and corroborative examples of how any human enviroment works.
As you say, the levels of the variables of an operating market always afford the observer a complete and thorough control for his endeavors in participation.
People can choose how they want to relate to the market system and most probably choose to endeavor to either participate or master the opportunity. From what I have seen, hardly anyone gets anywhere in satisfying their goals or aims. Mostly, what is there cannot be seen for what it is and wave after wave of popular distortions prevail as this culture banters about just what is what. This will never change because of the role of wealth or not having wealth is unchanging in any contemporary society.
The advent of data processing and analysis does make it possible to leave trend following by the way side but nothing in the public eye has made monitoring and analysis conventionally useful.
Certainly, evething needed is available to allow a participant to always "know he knows" with regard to any market.
What turns out to be the main distraction for most is their decisions to believe the many many myths of the markets.
In a dynamic equilibrium it is possible to have referent levels for the variables of the market. I always make sure I have a very broad and complete set for every event of the day. Events are the independent variable of the market.
No one has publically documented how markets work as yet. It might be that it would be construed as very risky to be so outstanding.
The conclusion is that, yes all the levels are there; they have flawless utility; and a full complete set is always available.
