USDCAD Bearish Retracement

Bearish Retracement with buyside liquidity sitting at 0.5 (Buyside we are currently at) and 0.618 (Buy side liquifity above) of fib. These are levels price could potentially reach before reversing and looking for sell side liquidity. Where ever a lower low is broken causeing a BOS (Break of structure), I would be looking for a bearish OB or FVG to set up shorts
