There was very strong resistance 0.7446 (based on Market profile and price action). There were very significant volumes traded there in the past. But it seems like the price went through it. If the market goes higher than 0.7525 I think this will work as a strong support and AUD/USD will shoot up.
If you like volume and market profile trading have look at my profile here at Trading View. I use mostly Market profile and price action for my analysis. Have a nice day.
