Just watched a program on National geographic "My Intelligent Brain", it was a sort of documentary on Chess Grand Masters in which they were trying to explain what goes on inside a brain of a Grand Master and in any normal human being (person who just know's how to play chess) while playing chess. What i understood was the amount of time people spend on their craft, grand masters recognized the chess patterns just like we recognize the faces of other human being and they anticipated the next move by their opponent, Pattern recognition is the key. If we clock enough screen time looking at one chart day in day out ( ex: 5 min time frame) at some point trader will start recognizing the recurring pattern and be able to trade them profitably.
