Regarding the EURNZD , we might be just at the start of a long term wave 3 which would correlate with a deep worldwide risk-averse mood given low OIL price, issue with China and the US Fed hicking rates.
Long trade is currently active with a stop below the previous higher low @ 1.6476.
Stay tuned for update after the FOMC minutes. I expect the Fed message to be received as neutral/hawkish. If that unfold as predicted, expect all commodities to go down and EUR, USD and GBP to go up.
