AUDUSD’s upside movement from 0.7501 extended to as high as 0.8135.
As long as the price is above the bullish trend line on the 4-hour chart, the upside movement could be expected to continue and a breakout of 0.8135 resistance could take price to 0.8200 area.
Only a clear break below the trend line support could signal completion of the uptrend.
