The strongest instinctive force in humans is to fight for survival. In the stock market, most people strive to make a profit.
Regardless of how many stock market trading books one reads, it will always be about the same old game. They will play with your emotions, they will mess up your logic. You will be tempted to break your own trading rules.
It is impossible to discern the ulterior motive behind every trade. However, one can already learn a lot by observing. For example, how market operators use sentiment or volume to drive stock prices up or down. This can be done by finding a group of participants (or brokers) that trade actively and act similarly. You just don't make analysis based charts and financials. Study local and foreign investors' behavior and activity.
You have to be aware of the manipulation that is currently taking place. Is it informational or transactional? Informational manipulation involves market participants/operators who spread false rumors or misleading information to influence stock prices. Transactional manipulation is also referred to as the volume play wherein market participants/operators creates an illusion of market activity by increasing trading volume and liquidity.
Will the market always be manipulated? Yes, probably in the short term but not perpetually. At some point in time there has to be a check and balance in free markets thus some securities cannot remain overvalued or undervalued forever.
Will you always be manipulated by the market makers and operators like how a predator hunts its prey?
Or are you willing to learn how to dance with the wolves?
