As expected, the Official Cash Rate was downgraded to 2.75% (from 3%) a few moments ago, which is causing right now the NZD falling sharply against all currencies. After the very dovish statement by the RBNZ, as you can see here, I believe the price can continue falling sharply during the next few days.
Here are the weekly and 1 minute chart, respectively:
NZDUSD, Weekly chart
NZDUSD, 1 minute chart
As such, after shorting the pair, I put my stop a little above the 38.2% level, around 0.63387, and I will let it run during the night (London time).
Other pairs could be interesting trading, like the GBPNZD.
