As shown in the chart regardless of the price.. we can see that for a position trader the relationship of this pair is proportional.
However for a small account or even a micro account, the difference in the proportionality of this two pair is too large and will definitely take you out on your trade.
My conclusion is that like the SNP500 the USDindex can be used as a indicator for trading other MAJOR pair and even other .
Pls . Comment on what you think about this.
