The eur/usd is an almost exact quazi pair of the usd/chf so their is no real difference its the same chart flipped upside-down, gbp/usd is also practically the same as the eur/usd with some minor divergences now-a-days with EU zone news. aud/usd and the usd/cad are also pretty much quazi pair with divergences due to commodity correlations. AUD-Gold/CAD-Crude. When all is said and done if horrible news or policy change comes out of the US they all move together including the usd/jpy, in my personal preference and experience I only hold one trade out of the (eur,chf,gbp/usd) group or one trade for the (aud,cad/usd) group. So in my mind the majors are really only 3 groups, when you include jpy. I pick the best set-up out of the eur group and the best from the aud group.....and i hate the usd/jpy🙄 This keeps my exposure to the USD limited. On the same note, when I first started trading I was sold on the idea of a 24hr market place and was under the assumption that I could come home from work, open my platform and trade 'only' EU/USD 5-15min. In my experience this was far from the truth.
