EUR/USD weakened yesterday close to the resistance at 1.3140 (17/10/2012 high). The hourly support at 1.3046 (04/12/2012 low) is challenged. Another support is at 1.3020 (intraday low, see also steep rising trendline).
The underlying trend is negative (see the succession of lower highs since May 2011 peak). Therefore we expect limited upside potential given the strong resistance at 1.3172 (17/09/2012 high) and the overall overbought conditions.
