The USD/CAD currency pair is moving in an ascending trend but the pair had a series of attempt to overcome the 1.3175 resistance level, which took advantage by the bears. In case that the bottom price restrained the upward trend, it will form an upward triangle that could help the US dollar to somewhat strengthen, which means a higher chance of a breakdown. However, when the price descended under 1.3100 region, then I think it is worthy to look for short positions.
