IT – INET PROD – New Go-Live date: Feb 21 for Enhanced Top Of Book - (9/13)
As previously communicated in IT Notice 1/13, NASDAQ OMX Nordic has decided to enhance the functionality of the Top Of Book (TOP) order.
This change will be available in INET Nordic Production on February 21, 2013 and included in the new version of the Market Model version 2.15.
We introduced the new order condition, the Top Of Book (TOP) order last year; allowing member firms to send in limit orders that are accepted by the trading system and added to the order book if the limit price is narrowing but not crossing the current order book spread.
NASDAQ OMX Nordic has decided to enhance the functionality with the following changes:
-
A TOP order also needs to fulfill certain minimum Order value criteria in order to be accepted. The TOP Order must always have a value exceeding EUR 5000, SEK 50 000, DKK 45 000 or NOK 45 000.
-
A TOP order that meets the minimum order value criteria, shall also be accepted and added to the order book if its limit price is equal to the current order book spread BBO and the value of existing orders at BBO (same side) does not exceed the value of EUR 7 500, SEK 75 000, DKK 67 500 or NOK 67 500.
-
Example: Initial Order book BBO = Buy 100@10, and Sell 200@12. Incoming TOP Buy order 1000@10 is accepted since the value at BBO is less than EUR 7 500.
-
All MPIDs will have the possibility to utilize the TOP Order functionality. Lower fees will however be offered to TOP order users who have assigned as TOP liquidity providers.
