Without trade knowledge is the worst of gambling. First visit dailyfx.com or fxacademy.com or you can search other sites in search engines for complete learning about Forex. First learn the basics and then create a demo account. Now learn and practice a demo account at the same time. When you become successful in demo trading then go to a real trading account. Maybe just buy a trade for profit and maybe you close it by earning a profit. But I think when you will buy. Pay attention to market position and calculate buy position if possible with you thinking with your good knowledge then you can place your buying trade or not.
