The prioritization service allows setting the order of clearing instructions and depository instructions on delivery versus payment terms (operation code 19/0) and free delivery (operation code 16).
Priority is applied in relation to other instructions with operation codes 19/0 and 16 for delivery of securities of the same issue, submitted to one depository account section and having the status "for execution".
It should be noted that other instructions (for example, with operation codes 36, 10, 20 and others, except operation codes 16 and 19/0) can debit securities reserved for instructions with operation codes 16 and 19/0 with priorities 1 and 2, in case of insufficient securities quantity.
