The dollar index on the daily chart you can see that we are now in a key area where it is testing resistance from February and November 2015, due to recent results from the US raising interest rates this has caused concern for investors and we have seen a big sell off, I believe we may see a big sell off again after the pullback to 99.26 0.382 fib or even gain strength and break back through the 0.236 fib at 101.00 and then break resistance as shown in the chart.
