Hunches and dreams = emotions.
That's a bold statement without anything to back it up.
Very little is known about the inner workings of intuition and interpretable dreams.
To write them off as "emotions" while treating TA as an actual science (and not just a craft) is pretty presumptive.
TA is simply reading a visual representation (aka chart) of prices in daily, weekly, hourly etc. increments. Those are real things that have actually happened in real life. TA does not claim to predict exactly future price movements. It merely provides the trader with an educated framework with which to increase the probability of profitable trades. It also allows a trader to identify entry and exit points with limited downside and defined exit levels should a trade move against him. It also identifies previous support and resistance levels.
I don't know what your knowlege of TA is or who told it was a "science" like biology or physics but its not. No one who uses it should claim it to be. Its simply chart reading.
And do you not believe that hunches or intuition and dreams are not influenced by human emotions such as fear and greed or excitement?
