The NZDUSD decline from .6550 is in 5 waves and suggests that the trend has turned down. A corrective advance is underway now and price is approaching the 50% retracement of the 5 wave decline, which is at .6395. The 61.8% is at .6430. Expect resistance at one of these levels. Hourly RSI is above 70 right now, so the rally may be stretched.
