澳元兑美元周一大幅走低，导致该货币对价格升至0.6355至0.63719之间的波动区域高点，随后买家纷纷出手，帮助推动澳元兑美元走高。

The sharp rally helped by peace in the Middle East, saw the pair move back above the 200-bar MA on the 4-hour chart and the 100 bar MA on the same chart, found upside resistance ahead of a well-defined 2025年周转区上限在0.65357至0.65516之间。Sellers have repeatedly leaned over the past several sessions. That area has now rejected price action on multiple tests, reinforcing its importance as a technical ceiling.

Despite the upside attempt, today's price action has turned lower. The pair fell back below the 100-4小时图上的条形移动平均线为0.64926, and if the price can stay below, will now eye support from the 200-bar MA为0.64658. A move below this zone would shift the bias more clearly back to the downside and re-open the door toward the broader support at 0.6407 and below that, a swing area near 0.63719-0.6355.

For now, the bias remains cautious with 短期阻力确认在0.65357-0.65516区域 and 移动平均线支撑位现在发挥作用.

关键级别：

• 抗性：
  • 0.64926 – 100-bar MA (now broken)
  • 0.65357–0.65516 – multi-test swing high zone

• 技术支持：
  • 0.64658 – 200-bar MA (4H chart)
  • 0.63719–0.6355 – swing area base where Monday's buyers stepped in

高点的失败和跌破100 bar均线使澳元兑美元处于弱势地位，除非下跌买家能够捍卫4小时图表上的200 bar均线。
