AUD/JPY fell 4% this week
The yen was the runaway top performer this week while the Australian dollar lagged. It was a classic risk-off pattern in the currency leaderboard.
In AUD/JPY specifically, notice that the pair took out the December high by a few pips only to stall out and crumble. It also made a head-fake above the 100-wma. Still, the decline this week didn't match the rally during the week before so the bias is still higher but I would get out of the way or get short on a break of the 200-dma at 72.26
Overall, this chart offers a great barometer for risk appetite.
