Hi Seforex,
I'm guessing you are VERY new to trading? Like pupils of anything it requires the student to find out the answers for himself to truly learn and understand. In trading it can take years, and I mean years of study so be prepared for a long and rocky road. Most people on these boards are still learning everyday me included, I still consider myself a complete newbie too.
A fantastic website that helped me (I'm not sure if the mods allow links here or not) is Babypips. Just google it. Read all you can on there and follow the school. This will teach you the basics, open a demo account and paper trade away, learn by doing.
Hope this helps,
Chris
