This technical development now leaves further upside risk targeting 1.0399, AUD-USD's Sept. 16 high. The Australian dollar-dollar currency pair embarked on a corrective recovery following a temporary bottom set at the 0.9386 level on Oct. 4. > > Bull or Bear? Vote in Our Poll A decisive break and hold above the 1.0399 level would turn attention to 1.0441 level, the pair's Sept. 12 high, with a breach of that level extending bullish pressure toward 1.0661 and then 1.0766, the pair's Sept. 1 high. AUD-USD's weekly relative strength index, or RSI, is bullish and pointing higher, suggesting further strength. Alternatively, support stands at the 1.0257/1.0290 levels, where a reversal of roles is expected to turn the pair back up. If that failed, we could see a push further lower toward the 0.9983/0.9926 levels. Further down, the 0.9767 level, the Australian dollar-dollar's Oct. 10 low, would be the next target. Overall, AUD-USD remains biased to the upside.
