We could see on Weekly chart that price of this pair has been moving in long-term flat since last 3-4 years. That's why I suppose that huge move could happen sooner or later. If you look through my last USDCAD ideas you could find that I would prefer to long a pair now rather than to short it.
However 44&77 HMAs cross is a very strong signal usually, especially if time-frame is Daily or Weekly. That's why I will try to short a pair from current. However, this trade is very risky, so it is not for new traders or someone who don't tolerate huge risks.
Good luck to everyone!
