The AUDUSD is trading higher today, boosted by risk-on sentiment as US stocks surge. The Dow is up 633 points (1.52%), while the S&P 500 and Nasdaq have gained 2.00% and 2.95%, respectively.

In the European session, the AUDUSD reached a new high, but struggled to sustain momentum above a key resistance zone between 0.6818 and 0.6823. The price briefly touched 0.68384 before pulling back to a low of 0.6786, and has since rebounded.

接下来的上行使价格回到0.6818至0.6823之间的关键区域，买家正在寻求重新获得控制权。0.6818水平代表2023年2月高点至2023年10月低点跌幅的61.8%回撤，而0.6823水平对应今年8月29日以来的波动高点。

对于交易员来说，如果价格能够突破并保持在该区域上方，买家可能会保持看涨势头。相反，未能突破这一水平可能会导致获利回吐和下跌试探

买家和卖家保持警惕。这对双方来说都是一个关键领域。
