If enough major buyers/sellers make decisions based off of TA then the market will move because of them
you can never know this.
People believing in astrology doesn't change gravity. How do you not understand this?
irrelevant. this is not what I said.
That does not mean that looking at a graph will tell you if the market should move up or down. But if 10 million in buy orders come in on Ethereum cause people see a teacup and decided to buy it then the market will move.
That does not prove that TA is correct. It demonstrates that belief in the TA is.
We can poll traders if they think people buying/selling because of a concrete reason, whether valid or not, will move the price of something and bet on it if you think it's impossible to know.
