DXY is inside a rising channel in monthly time frame and probably will reach to upper bond of channel.
As it is clearly shown in monthly chart , DXY has broken long term major down trend line and there is no major static resistance on it's way up to 121 ! . The only resistance which may be able to push it down is upper bond of mentioned channel ! Can these resistances make confluence at 121? Exciting !.
Daily time frame chart with focus on recent moves shows an up trend line with 5 hits with latest hit being the 5th. A bullish divergence was also formed between stochastic indicator and the chart. Unless seeing failure conditions, every evidence in multi time frame analysis is in favor of more upside move which signals more strong dollar.
I hope this analysis to be helpful and wish you all the best.
