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.
Thin hours get their own bucket
FIELD 49Test the setup where you can realistically execute it
Separate NZDUSD observations by active session and keep a spread or cost assumption beside each group. A setup that looks clean in a quiet historical candle may be less attractive when the target is small relative to real execution friction.
- Tag New Zealand, Chinese, and US scheduled releases without assuming their effect.
- Use a fixed rule for gaps and missing candles.
- Compare a later unseen period before adding a session filter.
