US Dollar Index could possibly play off the zone of Interest (Box Area); I use the Dollar Index as an indicator for my entries on Forex pairs; Positive and Negative correlation relationships. If DXY confirms on to the upside on lower time frame fractal the AUDUSD-NZDUSD will confirm to the downside at the same TIME on lower time frame Fractals. Which in part have a Negative Correlation with GBPNZD-GBPAUD. Inter-Market Arbitrage.
