The USDCAD rally stalled yesterday at the 100-小时移动平均线（MA）, reinforcing its significance as a key technical resistance level. Over the past four trading days, price action has been choppy, with buyers and sellers battling for control.

Today, the pair broke above the 1.4192 level, triggering buying momentum and pushing the price to a high of 1.4221. However, the rally lost steam following weaker-than-expected 美国住房开工数据（-9.8%）, leading to a pullback.

The price is now retesting the 100-小时MA, which serves as a critical short-term pivot. Holding above it would signal further bullish momentum, while a drop below would shift control back to the sellers, disappointing buyers.
