ORDER TYPES TO TRADE NON-DISPLAYED
Hidden Orders
- Orders above LiS may be entered as Hidden Limit orders.
- Non-displayed Limit Orders are hidden from other participants than the participant entering it.
- The Hidden Order stipulates a maximum purchase price or minimum selling price, and is ranked after visible Lit Orders at the same price.
Pegging Orders
- Pegging orders may be entered Non-displayed as Market-, Primary-, or Mid-Pegging, with a possible Limit Price protection.
- By using the Pegging order types, you authorize the INET trading system to automatically adjust the price of the Order based on changes in the visible Best Bid or Offer Price. This feature is called pegging, since the price of the Order is pegged, or defined, by a reference price.
- Besides the Mid-point Peg order type, commonly used in dark pools, it is also possible to peg to the best Bid or Ask including an incremental difference (expressed in ticks). This makes it possible to peg a hidden buy order to the best bid price + 1 tick.
- The types of pegging and the incremental difference (expressed in ticks) from the Best Bid Offer may be used in the following fashion for Bids and Offers.
Pegged Order type | Bids: Negative price difference Offers: Positive price difference | Zero difference | Bids: Positive price difference Offers: Negative price difference |
---|---|---|---|
Primary Peg | Displayed and Non-displayed Orders | Displayed and Non-displayed Orders | Non-displayed Order |
Market Peg |

Technical Details
Placement of non-displayed block orders in the Lit order book, exposing them for both Lit and LiS crossing order flow. Trading unaffected by MiFID II double volume caps. Orders are fully hidden, but any Nordic LiS Block trade will be published in real time. MiFID II post trade flagging and the fact that there is an execution on a non-published order will though indicate your hidden order. There is however no way for anyone else to see any order details.
Trading model: Continuous matching. Hidden orders are even valid during any Auctions. Pegged orders trade in auctions at their last pegged price.
Connectivity: FIX (Limit and Pegging) and OUCH (Limit). No separate port needed
Pegging to Primary Exchange BBO: Mid, Bid, Ask and Tick increments (+/-). No pegging over OUCH
Pre-trade transparency: Non-displayed orders. Any stub falling behind LIS remain hidden
Post-trade transparency: Trades in real time, voluntary post trade transparency
Matching priority in the Central Lit Order Book: Price, Internal, Display, Time
Time In Force for Nordic LIS Block orders: GTT, DAY, IOC, GTC
Minimum Acceptable Quantity (MAQ): Yes (allows aggregation on passive side)
