全球经济衰减10天前才开始?

OIL现在跌是在反应全球经济衰减，那么OIL10天前$147时它是在反应全球经济强健或高速成长了？

To me, oil has become nothing but a speculation stuff for the oil traders. When a bubble is on its way to be formed, the speculation stuff can become overbought, and then extremely overbought. That is how a bubble is formed. After a bubble is formed, it will pop, sooner or later.

You can disagree that oil has become a bubble. But technically, it will have a strong pullback, a strong one.

Check out what this guy said about oil: Oil has become "Purely a trading phenomenon", and it has nothing to do with supply and demand. I agree.
