  • Block trade:

    The use of pool reference is mandatory for block trades to link parent and children instructions.

  • Sell/buy - buy/sell back settlement:

    The closing leg must be linked to the opening leg using the message reference of the opening leg in the linkage subsequence A1 field 20C::PREV.

  • Securities lending and borrowing settlement:

    The borrowing/lending closing leg must be linked to the borrowing/opening leg.
