A buy on NZDCAD seems the most favorable option as price is in a correction phase. This correction can develop into two types of flats, Running Flat in "Scenario 1" or Expanded Flat in "Scenario 2". The only difference between these structures is that the latter breaks the low of Wave A while the former doesn't. And of course an Expanded Flat means more stalking time for the trade.
Trade with care. Use a strategy you have tested and verified.
