Will History Repeat Itself?

In June 2010 the Euro made a bull run close to 1460 pips. We are currently running near a 1122 pip gain. The weekly chart suggest we still have room for a continued run before a retracement. If we are indeed at the current top of the bull run then the retracement would be at the same point (50%) as it was in 2010. What are your thoughts?
