I just spotted a rising wedge on the DXY weekly chart which started with the dollar uptrend in early summer. As concerns over slower global growth increase over time , the Fed may shift its forward guidance and turn more dovish on its last 2018 meeting in the next few days. Combined, this bearish chart formation and maybe a more dovish tone from the Fed might end the USD bull trend. Breaking the lower slope of the wedge will be a confirmation signal of a reversal.
