@Irukandji2, (Pattern Completion Zone) It's the zone of which you expect the harmonic pattern to complete and reverse the trend of price action. In this case my Harmonic has the zone highlighted between the 1.272-1.414 but in reality the zone goes up to the 1.618 but i only learned that after plotting. It still managed to reverse significantly off the 1.414 though so it turned out nicely for those who saw the chart earlier.
