USDX offered some decent opportunities earlier in the year, GBP trended this year as well thanks to Brexit.
The issue IMO is that with rates on the floor most everywhere and not changing, little to no growth, stagnant trade etc. there's not much of a fundamental backdrop to drive significant currency trends. I don't see this changing anytime soon (would love to be wrong) so FX will be mostly about event driven moves, like GBP this year and JPY earlier in the decade with Abenomics.
