The Dollar Index is testing primary support at 73.00. Penetration of the declining long-term trendline is only tentative at this stage and failure of support would warn of a down-swing to 70.00*. Announcement of QE3 by the Fed on Friday would cause a sharp fall, while absence of further easing would strengthen support.
* Target calculation: 73 – ( 76 – 73 ) = 70
