Conservative take profit target at low 0.84XX region (previously resistance).
Liberal long term take profit target at 0.79XX region (highly doubt this will happen).
Due to not having a certain take profit target, I'd suggest using a trailing stop loss to lock in profits on the way down.
Consider exiting if price closes above the top .
Length of trade is unknown due to uncertain take profit target.
NOTE: This trade is heavily biased on whether or not RBNZ raises the interest rates next week. Markets are pricing in a possible rate increase.
If rates are raised: price may increase a bit but not much since it's already priced in. "Buy the rumour. Sell the news." Price should still drop a bit in the form of a retrace targeting the low 0.84XX region.
If rates aren't raised: expect a big drop.
