September U.S. Dollar's recent rally appears to be sustainable for more than a few days, albeit it needs to work its way through a couple of lines of resistance. Meanwhile, July Coffee and August Gold are looking to bounce off of their RSI trendlines. It looks as if (not guaranteed, of course) the dollar will drop on Monday, and coffee and gold will rise. However, coffee and gold's rise will be short-lived as the dollar resumes its recent rally later in the week.
