Every person can easily understand the situation of market but due to fud news any person can't understand the situation.because there is indicators that will give you a good option for buying or selling but some times bad news will create a crash.
That technical study gives some indications of which direction the market can move in the long run but for the short term mostly depends on daily news what is happening. But accordingly, to me, no one can predict/understand fully the market direction. Many experts failed many times to predict correctly.
