If you look at the chart below, which shows the last month CL price, what you see is a very definite trend. The dips have, variously, been caused by bad economic numbers and oil inventory numbers. The cause of the rises have not been so clear.
In effect there are five very clear low points in the chart, four of which occur between 75.5 and 76.
My assessment is that there is a very large player in the market with an standing, large buy order at 76.
It will be intriguing to find out where this goes.
