What are possible scenarios of implementing FIX messages on the client side to execute following orders?

  1. "Order1"
    OCO
    "Order2"

  2. List of: Order1, Order2, Order3…
    OCO
    "Order2"

  3. List of: Order1, Order2, Order3…
    OCO
    List of: OrderN, OrderN+1, OrderN+2…

Any examples of the message structures will be greatly appreciated.
