Reason for the trading strategy (technically):
NZDUSD is testing its resistance at 0.7378 (100% , 78.6% ), where we expect to see a reaction, causing price to drop to its support at 0.7261 (61.8% , 100% , 50% , 61.8% , horizontal overlap support). We do need to be cautious of the intermediate support at 0.7319 (61.8% , 100% , 50% , 38.2% , horizontal overlap support).
(55, 5, 3) is approaching its resistance at 97% where we expect to see a corresponding reaction. divergence with price has also been identified which contributes to our bias.
