I feel like i miss the boat or missing the even bigger one. 
As i want to develop new skills on trading i would like to know more about trader sources. What sites they use or which news sources they follow. And is there any book e-book you can advice? Thank you all answers!
I think you can refer to the classes taught by those who are not serious about studying and learning on the internet. To be able to trade successfully, you need to know technical analysis. Comply with market monitoring to be able to map out specific investment plans. You also need to be able to feel the market to be able to buy at the lowest price and sell at the highest price.
