The AUDUSD has seen volatile two-way price action ahead of today’s FOMC rate decision, but the broader bias remains tilted to the upside. Over the past two weeks, buyers have leaned consistently against the 4小时图表上上升200条MA (currently near 0.6462), reinforcing it as a critical support zone.

To the upside, the pair faces a 固定上限在0.65357和0.65536之间, marked by a series of swing highs. Multiple failed attempts to break above this area suggest strong selling interest, making it a key barrier to further bullish momentum.

A move 天花板区域上方 would open the door for more sustained gains, while a 跌破200 bar MA would shift bias more definitively to the downside and increase bearish momentum.

介于两者之间，4小时图表上的100柱移动平均线为0.64848。该MA是今日交易价格的基础。

随着美联储决定的临近，交易员将密切关注鲍威尔主席的任何鹰派或鸽派语气转变，这可能有助于推动澳元兑美元走出这一紧缩范围。

关键阻力水平：

• 0.65357-0.65536: Multi-point swing high ceiling area. Break above is more bullish.

关键支持级别：

• 0.64848： 100-bar MA on the 4-hour chart (initial support)

• 0.64625： Rising 200-bar MA – key support for current bullish bias

• 0.64072： Prior swing low; move below here would strengthen bearish case
