the only way I know that someone can trade forex is to first use a demo account and get as much experience as needed before they can use a real account. when you are in a real account, you have to learn to track your notes, how to read quotes and graphs too and yes you are right, practicing on a demo account will make you experienced and skilled. there is no doubt about that. but before starting to practice on a demo account, you need to have an overall basic idea about almost every aspect of forex trading. for this you must read several books and watch several videos, etc. and also forums are one of the main sources for learning. forums always react very quickly.
