Nice chart, though I'd be cautious with the upcoming FOMC interest rate decision on the 14th. Whenever there's a hike, there's always a spike then a massive dump + downtrend since it's already priced in, as I'm sure you know. However, recent soft US data has started to make people wonder if there will be one at all, e.g. inflation falling from 1.9% to 1.5%, NFP down, employment levels down.. Quite a few economists are speculating that the June hike may be postponed until hard data warrants a hike later in the year. Would be devastating for DXY seeing as a rate hike in June is already priced in by around 90% and in the event of no hike we could see an unprecedented sell off of the dollar.
Hope it works out for you though, I'll be watching this trade.
