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 below the 100-bar moving average on the 4-hour chart (blue line on the chart above), currently around 0.6484.

The question now is whether sellers can maintain pressure below this level. If so, attention turns to the rising trend line support and the 200-bar moving average on the 4-hour chart, 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 yellow resistance band near 0.6553–0.6565 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.
