Oil futures are running on a long downward trajectory

We are looking at crude oil futures , now from the monthly chart, is in a medium - to long-term down channel , two relatively clear support and pressure levels are $77, 33

Because current data suggest the us will dominate the oil market for the next five years. Given the cost reduction of shale gas and the secondary development of oil and gas fields in Texas, it is believed that the price of crude oil will not be strengthened for quite a long time in the future, and the economic growth uncertainty brought by the trade war and the situation in Iran will also have an impact on the price fluctuation. So I tend to oscillate more between $77 and $33
