1.0423 is a stubborn line in the distance. It capped the pair at the end of 2011. The round number of 1.03 was the peak of a move upwards seen in November 2010 and has found new strength after working as a cap in January 2012.
1.0263 is the peak of surges during October, November and December, but was shattered after the move higher. It’s far at the moment. The round figure of 1.02 was a cushion when the pair dropped in November, and also the 2009 trough. It is weaker now but remains pivotal.
1.0143 was a swing low in September and worked as resistance several times afterwards. Closer to parity, 1.0070 provided support around the turn of the year, and is now closer.
1.0030 capped the pair twice in March 2012 and proved to be strong. The very round number of USD/CAD parity is a clear line of course, and was a line of battle that eventually saw the pair fall lower.
Under parity, we have a new line at 0.9950. It served as a top border to range trading in March 2012. The round number of 0.99 provided support on a fall during October and also served as resistance back in June. It is now a pivotal line in the middle of the range.
0.9870 was a trough reached once and challenged afterwards, and serves a bottom border of the range. 0.9830 provided support for the pair during September and is now stronger after a first attempt to breach it failed.
0.9780, where the current run began is the next and important support line. It is closely followed by 0.9736.
