Humans don't determine price movement and never have all they do is trade against each other, you vs your broker.
Again, crowd behavior. If no person would determine price movement where would you get all that liquidity? Do computers or machines own those accounts that go into the millions? Who owns those robots that do the trading? The only difference between a human and a robot is that there is no 'emotion' involved but the robot is still owned by the human who prefers it to trade for HIM hence the human still determines what the robot does.
I'm not sure where you are getting at here but I definitely think you are trolling.
Lastly, if you think that trading is simply being on the right side of the trade without any semblance of an intelligent guess then your approach to trading is definitely gambling.
For me, the indicators are the tools that determine my probability while the price action is my reality. A good trade setup would definitely match my probability with my reality.
