USDCAD H+S?

Hi. Wondering if anyone else is seeing a Head and Shoulders pattern on the weekly chart for USDCAD.
I have yet to really utilize H+S patterns to help enter trades as I'm unsure when a pattern is confirmed, generally, and also didn't know if they should be looked for on a longer or shorter term, or both.

Sort of. I usually like to see more bars involved. I do however see a fib retracement action.
