It's reasonably well appreciated that the biggest component of the dollar index DXY is the euro. Therefore when trying toanalyse the future direction of the Dollar one needs to consider what is happening to the spread between yields in the two main economic areas (US and Germany as a proxy). If we look at US10Y-DE10Y historically we can see, as might be expected, when the spread rises/widens the Dollar strengthens. So to me, it loks like wwe are currently forming a bullish flag consolidation pattern in the yield spread, suggesting that at some point soon we will get a move higher in the spread, and with it a higher DXY.
