You're deliberately misunderstanding that you linked an article to EMH as informative and true, and then don't want to defend it. How do markets become efficient and reflect (any) information if nobody can profit by collecting information and trading on it? EMH states it's impossible to beat the market and that all available information is priced in. How, magically?
The way you're speaking about trading in terms of technical analysis implies you have retail trading exposure and have no idea what institutional alpha quants do.
