Under pressure by 1.3535 resistance, USDCAD pulled back from 1.3525. Support is now located at the bottom of the ascending price channel on 4-hour chart. As long as the pair is in the channel, the upward movement from 1.3223 could be expected to continue, and next target would be at 1.3600 area. Only a clear break below the channel support could signal completion of the uptrend.
