The Dollar Index has been on a buy signal since January, with potential over the next several months to D=108.38. A fall to the green line (x=102.56) would be widely interpreted as bearish, but as the chart makes clear, the move would be corrective and set up an attractive ‘mechanical’ buying signal.  The struggle at the red line (p=104.50) suggests the dollar is in no hurry to reach D, with the possibility that it will not reach it at all, or at least not for a long time.
