Adding up the % changes vs. the major currency pairs, shows that the EUR is the strongest currency today. The NZD is the weakest.
The EURGBP was up 0.82% in trading today as it moved above trend line resistance and squeezed up to the 100 bar MA on the 4 hour chart.
The NZDUSD fell below the 200 and 100 hour MA (green and blue line in the chart below) and tumbled lower. Staying below those moving averages will keep the bears in control (risk for shorts).
