On November 8, international crude oil went out of the "V" type reversal. In early trading, crude oil fell under the influence of uncertainty in the Sino US trade negotiation agreement, but subsequent data showed that the continued decrease in the number of us oil wells boosted the atmosphere of crude oil futures market, and the crude oil in Europe and the United States rebounded from the low level in the day, but the uncertain news restrained the rise of oil price. New York Mercantile Exchange West Texas light oil futures settlement price in December 2019 was $57.24 per barrel, up 0.09 USD / barrel, up 0.2% compared with the previous trading day, with a trading range of $55.76-57.48; London Intercontinental Exchange Brent crude oil futures settlement price in January 2019 was $62.51 per barrel, up 0.22 USD / barrel, up 0.4% compared with the previous trading day, with a trading range of $60.66-62.7 Buckets.
