The impact of the dollar on foreign exchange is that the dollar goes up, gold goes down, silver goes down, and crude oil goes down. All currencies denominated in dollars in Europe, America, Britain and America go down (the US and Japan go up), but it is not absolute, because the dollar goes up, the euro goes up, depending on who goes up much. Except for the index, everything in foreign exchange is quoted in the form of currency exchange, which depends on the rise and fall of the two currencies.
