Buying emerges for USD in European session as seen in the 4H heatmap. And that also majors USD as the strongest one for the day. 
H action bias of dollar also turned all up. (EUR/USD, GBP/USD, AUD/USD, NZD/USD down means USD up, just in case).
However, it should be noted that firstly, 6H action bias of USD is all neutral. Indeed, USD is in down action bias against EUR and GBP in daily chart. USD is also in down action bias against JPY, GBP and CAD in weekly chart. Hence, the momentum across time frame is not consistent. That means, the current rebound in dollar in counter trend.
For example, for GBP/USD’s we’d prefer to see a break of 1.4075 before weighing the chance of a near term reversal. Otherwise, GBP/USD is seen as in a correction only.
