Despite of the Fed inaction on Wednesday and better-than-expected Australian employment numbers on Thursday, the AUD/USD pair failed to sustain its strength above 100-day SMA and is seen extending its reversal from 0.7445, FOMC swing high resistance.Currently the pair is trading near session low, heading back towards weekly low level of 0.7330 touched on Tuesday. Earlier during Asian trading session, the pair spike to post FOMC announcement swing highs after the Australian jobs report showed the headline employment change stood at 17.9k vs 15k expected and the unemployment rate held steady at 5.7%.The pair, however, failed to build on to its up-move and was rejected back below 100-day SMA. Adding to it, risk aversion, leading to weakness in copper and oil prices, is also seen weighing on commodity linked currencies, including Aussie. The fall seems to have been arrested for the time being after the release of slightly lower-than-expected rise in US headline inflation number and higher-than-expected weekly jobless claims. However, a fresh bout of buying interest surrounding the greenback might now trigger a fresh leg of selling pressure and accelerate the downfall.Technical levels to watchWeakness below weekly lows support near 0.7330 would confirm 100-day SMA strong resistance and turn the pair vulnerable to resume its prior weakening trend towards retesting 200-day SMA support near 0.7270 region. A follow through selling pressure below 200-day SMA would open room for a fresh leg of downfall for the pair towards retesting May daily closing lows support near 0.7185-80 region.On the flip side, the pair need to build on to its momentum above 100-day SMA strong resistance near 0.7400 handle. A convincing strength above 0.7400 strong resistance, leading to a follow through buying interest above 0.7445-50 resistance, now seems to assist the pair to surpass 0.7500 handle and head towards testing its next major resistance near 0.7580-85 area.
