I don't agree at all and will show you why:
I have a list of figures and ask you if you can predict the next figure. The answer will be probably that it is impossible to predict the next outcome.

What is interesting now is the question: why did you come to the conclusion that it is impossible to predict the next outcome? The answer is that
YOU see no relation whatsoever in this serie of figures. And you are correct. To
YOU it is impossible to make any prediction and it looks like everything changes all the time randomly.
I can however make with 100% certainty a prediction for the next figure. Why?
Because I have more information, information that you don't have. I see the formulas that leads to the next result.

So people come to conclusions based on knowledge. No knowlegde means no result, having the needed knowledge will lead to the correct result. In markets knowledge is important too. You maybe have no clue why the market does do something, but maybe someone else has knowledge to know what will happen. Markets cannot move each time in a way that never occured before, because that would lead to an endless number of different moves. If you can find basic patterns in all these moves you have knowledge that others don't have. That makes the difference between a profitable trader and a losing one.
Trading is constantly solving one problem: where will the market go?
If you don't know the cause of the problem, you cannot solve it. First try to find the cause, and second try to find a solution for the problem.
