Since late June, NZD/USD has been pushing up against the 0.73-0.7325 area as we can see in the 4H chart below:NZD/USD 4H Chart 8/22(click to enlarge)Bullish momentum:- After NZD/USD cracked 0.73 in mid-June, price action came neutralized as it fell below 0.70 to make a lower low than the one we saw at the end of June.- However, price action picked up some bullish bias since then. - Price has crossed above, and is holding above the 200-, 100-, and 50-period simple moving averages (SMAs). - The rSI has also pushed above 70 and has since held above 40, which reflects maintenance of the bullish momentum. Resistance has become critical:- The multiple attempts and subsequent failure to break above the 0.73-0.7325 area has made this area a critical resistance.- If price holds below 0.73 and falls below 0.7240, we might have some further consolidation, but a break below 0.72 will be needed to take some pressure off of the key resistance area. - If price can clear the 0.7325 level, NZD/USD could be opening up to a short to medium-term bullish outlook.- To me, the bullish outlook exposes key levels around 0.7660, which involves a support/resistance area and the 200-week SMA.
