My simple understanding of technicals is just about identifying patterns. Stock markets are made by humans, held by humans and traded by humans. Human nature does not change nor does its pattern.
The key element of humans is sentiment. Now sentiment doesn't generally mean emotional sentiment, it also means intellectual sentiment as well. Interestingly, there is only one place where all these types and more get reflected. Do you know where?
You guessed it right, PRICE!!
The price chart always remains the same, what separates it is the eye looking at it. !
As a wise man said, every chart has two different views, either BUY or SELL. But to the experienced eye, a patient eye, a Calibrated eye, the probability levels are different and not just plain BUY / SELL. What separate is the levels of CONVICTION.
