NZDUSD — "the Kiwi" — is the smallest-volume major pair but one of the most interesting to trade. New Zealand was the first developed economy to hike rates in the 2021–2022 cycle (October 2021), and the RBNZ has historically been one of the most aggressive central banks in responding to inflation — creating strong trending periods ideal for backtesting.

Open FXAbsolute →AUDUSD is underrated as a practice pair and I came to it embarrassingly late. The macro drivers are simpler than EURUSD (iron ore + China GDP vs the full ECB/EU political machine) and the trend moves are longer and cleaner. The 2022 downtrend from 0.76 to 0.62 was driven by a deteriorating China demand story you could track in real time from commodity data. Macro pairs reward curiosity about the world, not just chart reading.
