So far, a trade-weited index is not available on Tradingview. There is also the Wall Street Journal Dollar Index called BUXX that is also not available on Tradingview.
Initially, DXY reflected the US trade partnership with the Euro , but it was never updated as US trade partnerships expanded globally. So, the trade weights in DXY is outdated. You will not get an accurate picture of what is going on.
The Trade Weighted U.S. Dollar Index can be found here at the US Federal Reserve's website: https://fred.stlouisfed.org/series/DTWEXM
They have also written an article called "Is a Strong Dollar Better than a Weak Dollar?" https://research.stlouisfed.org/publications/page1-econ/2015/03/01/is-a-strong-dollar-better-than-a-weak-dollar/?&utm_source=fred.stlouisfed.org&utm_medium=Referral&utm_term=related_resources&utm_content=&utm_campaign=pageone
And even if the dollar becomes weaker than ever, this would be good for exports and for stocks. Money will pour in more to support the US economy because of the value that it offers to investors.
