I have a question about oil futures. I want to begin trading oil futures. However, I realized that in order to trade oil properly I need to first know what causes prices to move. So what moves oil prices? Like when good economic data comes from the US, how does price react? How about when good or bad news comes out for other countries? I know too that anything political can have a big effect on prices. But any insight on what moves oil prices and in effect causes sentiment to shift to cause oil prices to move would be very helpful.
