The trade has been opened more on the longer term fundamentals than the shorter term sentiment given that the Fed are expected to hike this year and there is no Oil recover set in stone. Sentiment favours the CAD in the short term given the strong GDP reading today and oil remaining supported so I am hoping the 1.3400 handle can hold up against this until the sentiment swings back in line with the fundamentals.
Support is found at 1.3400 back to October 2015. The pair is in an uptrend with all MA aligned to the upside. Stop has been placed below 200MA which may provide support if the trade doesn't take off right away. 1.4500 is the upside high which provides this trade for a swing trade.
Most notable risk in the near term would be a poor employment report this Friday from the US and any positive news for a freeze in Oil production.
