As a guide, this would be the current (and perhaps for the rest of year) technical and fundamental bias:
STRONGEST (buy only): AUD, EUR, GBP
NEUTRAL to STRONG: CAD, CHF
WEAKEST (sell only): NZD, USD, JPY
Based on this ranking, any sell-off on pairs like: AUDJPY, EURJPY, GBPJPY, AUDUSD, EURUSD, GBPUSD would constitute a buy.
Pairs like: GBPAUD, EURGBP, EURAUD would be more tradable buying at support and selling at resistance – range trading.
NZDCAD, NZDCHF would be more ideal to short.
