The price of crude oil is certainly getting a lot of headlines, but, as usual, we need to look at some charts to get the true picture. Our surrogate for crude is the U.S. Oil Fund ETF (USO), which reflects the price of oil less the costs of actually rolling over the contracts. Currently, USO is testing the low set in March for the second time this month, during which time it has been restrained within a support zone defined by the lows set in January and March of this year. The bottom of that support zone is on the verge of failure.
