AUD/USD has been falling steadily since the early September high of 0.9400 to reach a 4-year low of 0.8512 on November 25.
On the daily chart, the bias remains to the downside as the market is below the Ichimoku cloud and RSI is in bearish territory below 50. The stochastic is approaching extreme oversold conditions, warning of some consolidation in the near-term. This is also shown by the tenkan-sen and kijun-sen liens flattening out. Prices are currently finding support in the area of the 50% Fibonacci retracement level at 0.8536 of the upleg from 0.6008 to 1.1078.
To the downside, the key 0.8400 level is seen to be the next support level, while to the upside, barriers are seen at 0.8794. Failure to break above this level will likely keep the downward bias in play.
