On January 28, the depicted support at 0.6400 acted as a prominent key level offering a valid buy entry. A bullish breakout above 0.6550 was executed a few weeks ago.
Bullish persistence above 0.6550 (depicted recent support) was needed to keep the price moving towards higher bullish targets.
The price zone of 0.6750-0.6840 constituted a significant resistance zone where signs of a bearish rejection were seen during the previous few weeks (triple-top reversal pattern).
On February 9, the NZD/USD pair failed to consolidate below the depicted support level of 0.6550.
Moreover, an obvious bullish recovery was expressed around the depicted temporary support level. Hence, the recent bullish swing towards 0.6750 and 0.6860 was initiated.
Yesterday, an obvious bullish breakout above 0.6860 was executed. Hence, the price level of 0.6860 now constitutes a recent support level.
Bullish persistence above 0.6860 is mandatory to allow further bullish advancement towards 0.7070 and 0.7170 where a prominent consolidation range was previously established in June 2015.
On the other hand, conservative traders can wait for a bearish pullback towards 0.6860 for a valid entry.
