IT – INET – Reminder on Updates to the Market Identifier Code (MIC) (ISO 10383) (63/15)
As previously announced in IT-Notice 43/15 and 51/15 Nasdaq Nordic and Nasdaq Baltic will update the Market Identifier Code (MIC) for First North Denmark and First North Iceland and include execution venue MIC Codes in FIX trade messages – LastMkt [30] from November 23, 2015.
The Market Identifier Code (MIC) a unique identification code used to identify among other exchanges, trading platforms and markets. The MIC is a four alpha character code, and is defined in ISO 10383.
For example, trades that are executed on the Nasdaq Stockholm market are executed with MIC code XSTO.
Currently, MIC codes are not relayed back on FIX executions; however the MIC code is part of the INET reference data.
Based on member request Nasdaq Nordic and Baltic have decided to implement three changes:
-
Change of two existing MIC codes for First North Denmark and First North Iceland.

-
New Segment MIC codes following the ISO 10383 standard to be used for Nordic@Mid trades in order to give an additional possibility to distinguish those from trades executed in the lit books, cf. the table below.
Note! Dark book MIC Codes will not be part of the INET Reference Data. Reference data will only show the lit MIC Codes since it's the same reference data for lit and Nordic@Mid Order books. The new MIC Codes for Nordic@Mid trades are only made available in the FIX LastMkt [30] field for the client to distinguish if a trade was done lit or dark by providing execution venue information. Currently dark book MIC Codes are only applicable for Nordic@Mid trades
