What you're looking at is what's known as a "railroad tracks" reversal pattern. Investor's Business Daily (IBD) does an excellent job of describing how to identify it and what it means going forward. I'll let them explain with my emphasis added:
The pattern is called railroad tracks because on a weekly [goldsqueeze edit: or monthly] chart, you'll see two parallel vertical lines. The horizontal hash marks denoting the weekly closes are not far from each other. Together, the two weeks of tight hash marks and similar vertical lines look like railroad tracks.
The stock essentially retraces a large price spread between similar highs and lows and ends both weeks [months] at nearly the same price. All of this happens in heavy volume.
If you see these tracks, it's almost always time to sell your stock partly because they often show up during a stock's climax run.
Fast trade without price progress is always a negative and can show up in railroad tracks.
It can mean that big-money investors are unloading shares. Eventually, the stalling action will morph into a fast decline in heavy volume. Often the price decline will be quicker than the rise was.
You want to get out before that decline gets under way.
Once a stock (commodity, currency, ...whatever) enters the parabolic phase, there's really no telling how high it will go or how long it will last. Given that, I'm not even going to try and make a prediction on the dollar. It might keep going for another week or another year - nobody knows. What I do know, however, is that parabolic moves end in parabolic disasters.
Now after all of that discussion, I have to caveat everything since today is FOMC day. The clowns at the Fed have the market on a leash, so, depending on what they say, we could see some wild action in the markets - currencies, commodities, stocks - everything. If they are hawkish (strong hints at raising rates), the dollar will/should rally. If they are dovish (they back off raising rates), then the dollar should tank. As always, we shall see.
