EUR/USD has broken the support at 1.3709, validating a short-term double-top. A test of the key support at 1.3621 is expected as long as prices remain below the resistance at 1.3723 (17/12/2013 low).
In the longer term, the decline from the peak at 1.3832 (25/10/2013 high) indicates a significant exhaustion of buying interest. Coupled with overbought conditions and other nearby resistances such as the long-term declining trendline from the 2008 peak at 1.6038 (around 1.3917) and the psychological threshold at 1.4000, the upside potential seems limited.
