EURNZD H4 Analysis for possible Day Trade

Price has been in a long term downtrend and has come down to a level at 1.65710 created since July, 2019. Price didn't hit the level but it came within that zone and created another level (1.66316) that has been tested severally but unable to breakout for about 20hrs.
Price is showing sellers exhaustion so i'll love to see price breakout of 1.66316 and pull back for a retest or HL formation. When that happens i'll be looking for buy entry on the 15mins.
