People will offer you links to different news sources and such. And most of that is good information. However none of it will help you predict the increase and decrease of the price. It's impossible to do so. People have been trying to predict future asset pricing for centuries. It's simply not possible to predict precisely what will happen tomorrow.

Two concepts to consider:

1) Trends mean something...what's been going up a lot may come down, what's been falling for a while may pick up

2) Buy and hold is your safest play
