Trading can be fun to those who has already known what to do and how to apply the right tool and at the right time too and not for those that don't want to learn or study to know more about trading before deciding to take action on it. Though trading it's never an easy thing but there are some people who are benefiting from it, which is why it's important for people to acquire knowledge first before deciding to do what you want.
