The price is now re-testing 1.3878 and provided that Eur remains strong, it will reverse up and head for another at 1. 3900 . Traders should look for any sign of strength in the current pullback to join the pair in the upmove.
The price might also fall down significantly below 1.3878, I assume that a retracement to 1.3850-1.3860 might be that sign of weakness needed for this scenario. Then I would wait for a re-test of 1.3878, which is a high potential entry level for a short trade. In this case Eur might fall to 1.3800.
