Koorosh asked me some time ago for a comment on this pair; my brief answer earlier is reflected in the H4 chart and bit of fundamental (il)logic !
I am bearish sterling – like most of the world – and cannot get to grips with the recent kiwi strength; I am of the view that a sterling collapse has to drag the kiwi with it. Simplistic I know.
Last week I posted my view that 1.80 should see a bounce and indeed it did but not for long. Nonetheless I would prefer to be long on dips with a stop below 1.7950 (clear break) targeting a break of the channel (increase position ?) then targeting 1.85.
