IT – INET Nordic – Update - Improvements to Pegging of Large In Scale (LIS) Orders (8/16)


As previously communicated in IT-Notice 69/15 and 4/16, Nasdaq Nordic and Nasdaq Baltic have decided to further enhance the possibilities to trade Pegged Non-displayed Orders in the Lit Order books. With this enhancement “stubs” falling below the LIS threshold will be allowed to be re-priced due to change of BBO without being rejected by the system under the condition the Order is submitted with a Limit price.   

Note that a Non-displayed Order has to be large in scale (LIS) at the time of entry. If the volume is reduced due to a partial execution, the Order remains non-displayed even when smaller than large in scale (LIS).

Large in scale (LIS) is defined as specified in the table below:

 

Class in terms of average daily turnover (ADT) ADT <
€500,000
€500,000
≤ ADT <
€1,000,000
€1,000,000
≤ ADT <
€25,000,000
€25,000,000
≤ ADT <
€50,000,000
ADT ≥
€50,000,000
Minimum size of Order qualifying as large in scale compared with normal market size € 50 000 € 100 000 € 250 000 € 400 000 € 500 000

Example:

A Pegged Non-displayed Order with a value of € 55 000 is partially traded below the LIS threshold of € 50 000. The leaves value or “stub” is after the trade € 45 000 and the Order remains Non-displayed. In event the Order gets re-priced due to a change of BBO, the Order is replaced at the new price level, still as a Non-Displayed Order after the introduction of this enhancement. Note that the Order needs to have a Limit price, otherwise the Order will be cancelled when re-priced by the trading system.
