Trading currencies is all about finding strength and weakness - the CAD/JPY is the best cross these days:
The CAD is very weak with slowing economic data and also the sell-off in Crude is hurting the CAD. On the other hand, the JPY is rising sharply with risk aversion flows.
Crude just broke $31 and is off to new 12 year lows. As of writing this, the Shanghai Composite is going lower although not as strong as recently which could add to JPY strength.
