It appears humans like to create patterns in randomness. Almost every TA trader I have watched are hindsight talkers. Trading is difficult and even the very few inefficiencies that exist(if they actually do) does not exist forever and there is always the search for new once. Now we are competing with AI which can create limitless amount trading ideas and backtest them based on its database to find edges or inefficiencies faster than any human can ever do.
However, sitting in front of a screen to analyze chart patterns so as to predict the future prices just looks like BS. Although to be fair, maybe if everyone does it becomes a self fully prophesy, even though it makes no sense.
The short video above is interesting. Take a listen.
