A lot of commodities that benefit australia are lower including CNXmetal, iron, copper as well as the COPX which somewhat represents copper. AU200 is also a lot lower
I think we also move lower as we go into more global tightening and stocks/risky assets continue to fall and risky currencies like AUD suffer more so than currencies like CHF who should benefit. The fed meeting this week may also help push this lower if they are hawkish with US CPI rising again last week and sparking more hawkish speculation because of it.
We've made lower highs since about the end of March so i think a stop above the most recent high makes sense.
