i just followed a discussion in the chat room and thought i might be useful to look at from another point of few

this is the nikkei 225

this is the aud/usd chart

they are nearly identical.

this is what i think drives the aud/usd when the news are not spectacular. aud/usd has a very high correlation with the stock market. i found it helpful to keep this in mind. hope this helped, of if have another idea looking forward to hear it, cheers joachim
