You should find a lot of free resources about trading on the internet. I recommend starting with babypips website. As far as I know that walks a beginner all the way to knowing quite a bit about trading and markets (especially forex). Now.. trading is not about theory and even if you read all the books and articles on the internet you might still lose money. It is more about practicing and learning from your mistakes. Ultimately your goal is to get "in sync" with the market. Some traders can literally feel the pulse.
Focusing with your understanding in every books or videos that you read and watch, then apply it when you are already inside the platform, in your first attempt expect that things won't be that easy for you, chances that you'll lose is very high though with the help of those handouts that you read you'll be able to minimize your loses and continue to proceed facing the next chapter of your trade.
