USDCAD potential buy - strong weekly support

Price is currently @ weekly support 1.29000 and may possibly be forming a double bottom on both the 4H and D1 timeframe. I am expecting either a a 38.20%, 50%, 61.8%, or a 78.6% retracement to coincide with an advanced pattern. Price is @ a good level to buy as in a clear trend channel. Before entering look for further confirmation from candle readings on lower TF.
