Trading spot crude oil is actually a business in itself, not just buying and selling. To do any business, you need quite detailed pre-market research, reasonable planning and thoughtful post-service to do a good job. But why do many professionals become "gamblers" once they come into contact with financial investment? I only look at business and hope that I am right. The reason why countless novice traders often fail is that I can't see the difference between "gambling" and "professional trading". When I heard some irresponsible practitioners advocating how to invest in spot crude oil to make money, I was duty-bound to join the army of losing money. Are you really ready?
