Trend is down in USD/CAD currency pair in 4 hours time frame. Vital resistance is present at 1.3309 price level. So far the current drop in price looks like A, B and C Zig Zag corrective wave pattern. So, price may try to rise back up. However; as long as price stays below 1.3309 price level, I expect price to drop one more time. So, a good idea is to only look for sell trades as long as price stays below 1.3309 resistance level in four hours chart of USD/CAD currency pair.
