IT – INET Nordic – Improvements to Pegging of Large In Scale (LIS) Orders (69/15)
Based on member request 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 without being rejected by the system.
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.
