Alk,
you need to gain experience on a part-time basis before you could attempt moving full time.
If you a complete newbie you need to running on
demo trading for a while to become comfortable with the market and to develop a "feel" for forex.
This business has a very large learning curve and i suggest you take things slowly to begin with and you will learn to appreciate how complex the market is.
When you are comfortable and not losing bagfulls on demo, you could start mini-trading on 10k lots.
The rest will fall into place when you have come that far down the road.
good luck
