Crude oil
The USDCAD fell lower into the NY session opening, reaching a low of 1.3600 (nice round, natural support level). The fall, took the price below the 1.3636-49 area which is home to a number of swing lower going back to the end of April. The break failed on the first test. Technically, the area becomes support again. Stay above is more bullish. Move below, more bearish.
The move lower today was helped by the rise in Crude oil (Saudi and Russians say they will adhere to production cuts). The price of the futures moved up to $49.66 today. That move took the price above the 200 day MA at $49.15. The price has since moved lower and currently trades at $49.22. If that level holds, that could lead to more weakness in the USDCAD.
Regardless though, traders will be watching that 1.3636-49 area for technical clues on that chart.
