Books recommended above are enough to teach you about trading, but you can also visit YouTube and watch some tutorial videos on how to trade, but videos you see on YouTube might be talking about profits alone, and in trading, their is always profit and lose, but make sure your profit is more than your lose.

You should know that its not all about watching videos and reading books, you have to put everything in practice, and you have to start with little amount you know if you lose it wont affect you. Don't think because you have watched different videos and you will think you know everything already, and you will end up starting with big amount of money, its not done like that, you have to start practicing gradually and you will develop your own strategy, everyone one is having strategy that works for them.
