AUDUSD is unfolding a bigger bullish impulse since May of 2017. We see an overlapping activity within first wave 1), folowed by a minor correction within red wave 2) and now a strong and sharp wave 3), which looks to have found a top near the 0.8100 region. That said current wave 4) may unfold a minor three wave setback as in a A-B-C manner and can search for support near the Fibonacci ratio of 38.2. Once wave 4) fully unfolds, a new push higher into red wave 5) may start to unfold.
