Where can you Learn everything about stocks market and trading?

Forget the Wall Street Journal, though--read Investors Business Daily (IBD), instead. It's a better newspaper and it is built around a particular approach to trading. You could read _How to Make Money in Stocks_ by William O'Neil too--he's the founder of IBD.

Search your 

Local library for other books on stock investing. Try to absorb as much knowledge and understanding as possible. Over time, you must open a brokerage account and paper trade for a while - this is a practice (not real money).

Well understand 

That we will never know everything about this and the market will always do what you want to do regardless of what their positions are.
