  • Block trade:

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

    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.
