US crude oil short-term trading advice: Range-bound oscillation, sell on rallies, buy on dips

(1) Analysis: US crude oil inventories have unexpectedly increased, putting short-term pressure on oil prices; however, the transportation risk in the Strait of Hormuz remains high. Supply concerns are limiting the downside, and the weakening US dollar provides additional support. Currently, the market is still pricing in a premium for geopolitical uncertainties, so wide fluctuations may persist in the short term. Pay attention to whether range support is effective. (2) Key focus: geopolitical situation, inventory data, US Dollar Index. (3) Resistance: 83.00, 84.50, 85.00. (4) Support: 81.20, 80.50, 80.00.
