How can you be sure? It seems kind of asymmetric to a chicken and egg dilemma in my mind. People follow TA and therefore act in a certain way that makes TA accurate. Or people act in a certain way and TA is able to accurate predict that. I truthfully do not know which one is truth.
I guess either way does not matter, what matters is that it tends to work.
It's what they call a self fulfilling prophecy.
If you have enough followers that do what you suggest, then you have a high probability it will happen.
You invest ahead of your advice and you can float your winnings and get more people aboard.
I am familiar with the term and would agree that it fits my thinking. As I said I guess there is no way to truly know which it is, only to know if it comes true or not.
there is of course no way to be sure since variables can't be isolated in markets. but we can make some logical deductions to know that there are at least forces outside of TA and traders practicing it. for example, many investors don't use TA at all. they buy and sell based on fundamentals or based on no analysis (hype and panic, etc). these people must have an effect on the market. and i know from experience and observation that holding a position deep in profit or loss causes investors to act on fear, greed, capital preservation, etc. traders following TA inevitably affect the market as well, but i just don't think there's evidence of the "self fulfilling prophecy" idea.
Do you not think it could be that these people act in such a way because of the knock-on effects of people following TA? As someone not following TA and relying much more on fundamentals and overall market sentiment - I can't help but realize that most of my thoughts and my actions are in line with TA.
Anyway, I suspect that on this debate we'll continue to go in circles, thank you for the discussion either way, it is always helpful to try and consider things in an alternative way to the one I am most inclined.
