Today USD strengthened against every major currency. Investors are now realizing that dollar is still safe to invest in. Euro might suffer if U.S. Fed starts tapering resulting in tightened global monetary conditions. Investors are avoiding risk and therefore all emerging market currencies are suffering. Today US data for pending home sales came out which fell 1.3% in July from June but it didn't affected the currency. I think the market is focusing on all the employment related data which is coming out next week.
