Being contained by the upper line of the price channel on 4-hour chart, AUDUSD pulled back from 1.0687, suggesting that a cycle top is being formed. Deeper decline towards the lower line of the channel would likely be seen in a couple of days. As long as the channel support holds, the fall could be treated as consolidation of uptrend from 0.9861, another rise towards 1.0900 is still possible after consolidation, and a break above 1.0687 will signal resumption of uptrend.
