AUD/USD Technical Analysis: Bulls need to beat resistance at 0.7221

• The bullish divergence of the 14-hour relative strength index (RSI) and a rise to 0.7219 on the back of an above-forecast Aussie Q2 GDP reading, though encouraging, is not enough to call a bullish reversal. 
• Only a convincing move above 0.7221 (falling trendline + 100-hour MA) would confirm the sell-off from the Aug. 28 high of 0.7362 has ended at 0.7157 and could yield a rally to 0.7270 (200-hour MA). 
• On the downside, acceptance below the previous day's low of 0.7157 would signal a continuation of the sell-off.
