Possible setup for AUDCAD

Price has been trending downward with clear lower highs and lower lows since the end of February 2021.
These are two possible scenarios that I see playing out.
I could buy when price breaks resistance and confirms the buy by retesting that broken resistance (now new support).
I could sell when price breaks support and confirms the sell by retesting that broken support (now new resistance).
Always wait on a retest to confirm the setup before any entry.
