from the daily chart of USO, you can see that Monday, Tue and Wed, the volume is about 3 times of average. With such huge volume, the USO did not go down, instead, it was flat. Why? I think it is showing institutional buying.
At this point, USO at that level has a strong support, and unless this support is broken, it is hard to judge that the USO will be down.
really sorry, this time, hard to agree with you, but i may be wrong.
