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.
