Forex is notoriously difficult area to grasp
As you can see from a longer term chart below there's... whipsaws everywhere...no valid support/resistance lines ...no decent trend lines,... and no chart patterns...there's not much to work with...
Showing a broader picture of where the NZD/AUD is heading is limited ...I have added the standard Deviation channel and the 200day moving average.. and even then I would have little to no confidence as to whether a breakout would be genuine ...

So where is the NZD heading?...I have no idea but at this moment it is still tracking within its downward SD channel.
