Possible Buy Opportunity on USDCAD

Looking at UsdCad, we could be seeing a potential buy setup forming. At the end of last week, price closed below the hourly horizontal level that is clearly identified. At market open, price had a bullish push past the level is currently pulling back to retest as support.

If price could present bullish rejection by wiping out the M15 horizontal level, that will identify a sign of strength for me. I'll be waiting for a break of this market structure before thinking of buy orders.
