People are unpredictable. Trying to read people's minds is impossible. Not to mention that there are BIG traders behind the markets with BIG money who buy and sell against the majority but because they have BIG money, they are the main movers even though they are very few in numbers. They're usually known as price manipulators. You can't read their mind so it's best to stick with the chart and try to analyze the data without any emotions/bias and come up with predictions :]
