USD currency affected so much by fundamentals

I glimpsed through the Forex Gump's article at Babypips.com and found out that, the USD most probably affected by the economic reports from 2012 and onwards.  This means to me that any position whether buying and selling better be based on the economic reports.  Technical analysis is also to be considered but, the fundamentals should come first.  Trade using the technical analysis when there is no major high impact reports.
