I always pay attention on Divergency - there is usually great support for a trader who is based on Technical Analysis. I have marked my GBPUSD with a similar situation. Thus I prefer to looking for it on 30 minutes charts. Sure, not always this sign is right, sometimes price makes huge moves in opposite direction. Anyway, I could recommend to pay attention to USDCAD because of divergency. But anyway make your own analytic before choosing any direction if you going to trade it. And of course there are no simple trades - Risk Management ABSOLUTELY mandatory.
