Since some weeks we were scanning a down turn, now seems more plausive because the last rally has reached the 76.4% retracement of wave 1 which is pretty common for a 2nd wave of an impulse. At the same time we can observe a clear divergence in the stochastics that could signal us that the probabilities for the rally to continue has diminished. There for if breaks the most visible support i suggest to sell dollar at least until the 78.60 be reached. Wait to a close of day below the 81.93 to consider the support broken.
