The AUDUSD stalled yesterday after briefly breaking to a new high not seen since November, only to reverse lower. The failure to sustain the breakout has shifted the near-term bias more cautious, especially as the pair now trades 4小时图上低于100柱移动平均线（上图上的蓝线）, currently around 0.6484.

The question now is whether 卖家可以保持压力 below this level. If so, attention turns to the 上升趋势线支撑 and the 200-4小时图上的条形移动平均线, near 0.6450-0.6459, as key downside targets. A break below those levels would open the door for a deeper correction toward 0.6407 and beyond.

On the topside, the 黄色阻力带在0.6553-0.6565附近 remains the ceiling. As long as price stays below the 100-bar MA and this resistance area, the bias leans in favor of sellers probing lower ground.
