what is the meaning of price action?
it means everything is in the price and everything that we need to know is in the price.
it is in front of us.
to be read like a book or newspaper-digital of course[

].
now i agree with Brooks that every bar has a reason to be there but why it is there, may not be relevant to our objectives. a 5 min bar is not going to be relevant to a long-term investor.
It has taken me twenty years to find that my original belief that markets are rational. [sic!]
100% of the people who are not traders or investors, by their own choice, would find this belief ridiculous.
According to reliable sources only around 2% of people in the world, are market participants so 98 % of the people would believe that the very idea that markets are rational, is absurd
if markets are rational then they can be predicted, not like Nostradamus predicted, but by reading/observing the present bar or bars. That is by focusing on the past.
This is what Brooks was trying to tell us.
