The NZDUSD pushed higher yesterday and extended the move again today, but upside momentum stalled where it matters most technically.On the hourly chart, the pair made three separate attempts to break above the 38.2% retracement at 0.57714 (from the March 20 high). While price briefly traded above that level twice, buyers could not generate enough follow-through to test—let alone break—the falling 200-hour moving average at 0.57808. The rally peaked at 0.57764 before running out of steam and rotating back to the downside.That failure near key resistance was telling.The price has now moved lower and is testing the 100-hour moving average at 0.57406, which becomes the next key barometer. If sellers can push and hold below that level, it would shift the short-term bias back in their favor and open the door for a retest of the lows from Monday and Tuesday.The buyers had their opportunity over the past few sessions, but they couldn’t clear the technical hurdles needed to take control. With momentum fading near resistance, the sellers now have the edge—and a chance to press the downside if the 100-hour MA gives way.The buyers have given up and the price has now rotated lower. The price is down testing the 100 hour MA at 0.57406. If the price can get below the MA, that would give the sellers more confidence and have traders looking back to the lows reached on Monday and Tuesday. The buyers took a shot over the last few days, but could not get over some of the humps needed to take more control. Now, the sellers have the shot to exert the pressure once again. Watch 0.5740 for bias clues. If the buyers can stall, the price remains in a battle with the buyers and sellers leaning against the 200 hour MA above and the 100 hour MA below. If the sellers can push back below the 100 hour MA, the sellers can make another push to the lows for the week. This article was written by Greg Michalowski at investinglive.com.
