The GBPNZD is somewhat comparable to the GBPAUD. It is corrective on a higher time frame and in this case I am also looking for a last leg lower. Since I see this bearish move as a correction I also like a corrective wave pattern. 7 is and extension of 3 which is corrective. I'm currently short on this pair for that new low.
However once the bearish move is over I expect an impulse higher, that's the trade you don't want to miss.
