No, not really because you have to take into account the pegged currency, which can out- or underperform the dollar. If you notice, the USDCHF tracks the DX almost identically, while the USDJPY and USDCAD can decouple.
They decouple when there is another important trend in the opposite currency. Right now, the only trend is in the dollar, so all dollar pairs perform more or less the same. On the long run, 1% more or less wont matter.
Yea, I would agree the highs unlikely to be taken out (aka flat correction), although they could be temporarily (expanded flat)-- just addressing your resistance line that has a good chance of being broken to the upside in the near term, don't buy the breakout.. C wave going to bring it back down xD.. Bullish gold on weekly TF
