A break above that key level opens the door for a test of 50% fibo resistance from 1.8501-1.7042 at 1.7773.  Intraday oscillators have been helpful lately given the persistence of the recent range.  Hourly RSI sloping down from overbought levels and MACD creeping towards the 0 line point to a possible return to today’s low at 1.7480 with further weakness exposing the 50% fibo of 1.7248-1.7616 at 1.7433.
