US crude oil short-term trading advice: fluctuating upward, buy on dips

（1）Analysis Reason: US crude oil fluctuates repeatedly around $65. The US and Iran have agreed to continue negotiations, easing concerns about short-term supply disruptions and causing risk premiums to marginally decline. However, differences over enriched uranium remain, and with the US extending restrictions related to Russian energy, supply prospects are still uncertain. Overall, the market lacks unilateral driving factors, fundamentals have not shown clear tightening signals, and the technical structure is in a converging consolidation phase. Trend momentum is weakening, and in the short term, the market is more likely to oscillate within a range, waiting for news catalysts to break the balance.（2）Key Focus: Geopolitical situation, inventory data, US Dollar Index（3）Resistance: 65.30, 65.80, 66.30（4）Support: 65.00, 64.50, 64.20
