The dollar is trading more mixed as it holds marginal gains against some major currencies but keeping lower against the antipodes in trading today. EUR/USD is down just 0.1% to 1.1753 while GBP/USD is down 0.3% to 1.3540 currently. The latter owes to some softness after a weaker UK PMI data earlier here. However, the odds of a BOE rate cut in August hasn't shifted materially and is the same at ~83% for now.Besides that, USD/JPY is now back up by 0.1% to 146.60 after being down earlier to around 146.05 at the start of the session. The pair is hoping to snap three straight days of declines, though sellers are very much in control still. The 100-day moving average at 145.68 is a key technical point to watch.But for today itself, the more interesting currency pair will be AUD/USD after it pushed for an upside breakout yesterday.The pair pushed above the resistance region around 0.6590-95 and is now holding at the highest levels since November last year. There's not too much catalysts for the fresh climb here as it mostly comes amid a softer dollar and a pick up in risk appetite in the past two days.From a technical standpoint, it is inviting scope for a further run higher with the November high last year only seen at around 0.6680. Other than that, the 200-week moving average is next seen at 0.6708 currently. So, that argues for the potential for a technical extension higher on the break we're seeing.Dollar sentiment will be the main driver to test buyers' appetite. And that will come about in the form of US data later in the day. We'll have the weekly initial jobless claims and preliminary PMI data for July coming up.Head on over to investingLive (formerly ForexLive) to get in on the know!
