You should also get a little bit familiar with the most basic fundamental aspects in the behavior of gold, the euro and the dollar.
An other source is Marc Faber. Find him in the net. I know him personally. He is an adviser to a friend of mine and his study's and posts are based on fundamentals and less on chart techniques.
Edit : Otherwise it gets to complicated. Here the link from Prof. Faber :

An other source you can use is the free " Currencymagazine" or the free " Options and Future" trader magazine. In those magazins, you will see charts, which give you some more information.
Take care and good luck
