To be honest, there is a lot of fake news as well what has been made just to drive the price into one or other direction, so you can use only very reliable sources like Bloomberg if you want to, but I will suggest better follow technical analytic data.
The data available of course is the only reliable stuff to rely on for it put aside all the fake news and opinions by those who want to disturb the market. Besides Bloomberg, there are few other sources as well that gives you the exact figures. Ultimately everything boils down to the term of trade as well. Despite every formula that can lead you in the right direction to make money, invest long term and forget about it. A period of five years it enough to make you a millionaire.
