As the trading day nears its close, 美元兑瑞士法郎正在测试其多周交易范围的下限, which has been in place since mid-December. On the 4-小时图, the pair 两周前在一月高点形成双顶 before reversing lower. Last week, the price 在区间支持处找到买家（0.8965 - 0.8975） and rebounded, reaching a high of 昨天0.9054 before turning lower again.

Today’s 美元普遍疲软 has pushed USDCHF back to the 下回转区上界（0.8965 - 0.8975）, with the latest low touching 0.8975. This level now acts as a 买家和卖家的关键晴雨表 heading into the next session.

关键技术水平：

• 支持：

  • 0.8965 (break below here could open the door for further downside)
  • 0.8914 - 0.8927 (next key support zone)
  • 0.8882 (38.2% retracement of the December-February rally)
  • 0.8800 (100-day moving average)

• 阻力：

  • 0.8997 - 0.9011 (higher swing area, reclaiming this would signal a continuation of the range-bound pattern)
  • 0.9054 (recent high, a break above strengthens bullish momentum)

A 跌破0.8965 could accelerate downside momentum toward 0.8914 - 0.8927. However, if buyers defend this support, a rebound toward 0.8997 - 0.9011 would reinforce the ongoing 区间价格走势 that has defined USDCHF over the past two months.
