AUD/USD has been failing quite often to break resistance at 21DMA from the last couple of months (see monthly charts), as a result, we think since it doesn't manage to break above decisively on a closing which would likely create more potential in days to come.
Meanwhile, have a glance over intraday charts, the interim bulls form a three driver pattern on 2H charts.
The failure swings have collapsed to the support of baseline at 0.7508 levels which signifies the weakness in the pair.
On intraday terms, and noise with strong momentum to signal selling pressures as they are diverging to previous minor upswings.
As you can observe volumes are fading on every rise in price, which is another substantiation of failure swings (bears shrugging off these upswing rallies).
On a speculative basis, traders can use one touch binary puts for targets of 25-30 pips with ease.
While on delivery basis, stay short in near month if the pair does not manage to hold onto 0.7560, then 0.7458 or below levels in near terms is a quite possible bet.
