In IT Notice (70/15) , Nasdaq Nordic announced plans to utilize the ability of GCF to have the symbol field longer than 16 characters (up to 32 characters). In order to allow market participants more time to prepare for this change, Nasdaq Nordic has decided to postpone the production launch date of this change to February 1, 2016 .
As previously communicated, the change applies only to Exchange Traded Products and will be used when the issuer requires a longer symbol. As an effect, the symbols relayed over ITCH (Order Book Directory - Symbol) and GCF/TIP (BasicDataTradable [BDt] - Symbol [SYm]) can have different values. Please note that the ITCH symbol will not necessarily be a truncated version of the GCF/TIP symbol.
This change is planned for Exchange Traded Products on Nasdaq Copenhagen, Helsinki and Stockholm. Issuers of Warrants, Certificates and Exchange Traded Notes may opt to provide a longer symbol in addition to the current symbol. Where both values have been provided by the issuer, the longer symbol will be disseminated within GCF/TIP as Symbol [SYm]. Where no value has been provided for the longer symbol, standard symbol will be disseminated via GCF. As per current setup, ITCH will continue to disseminate the standard symbol within the “Symbol” field. This new handling of the order book “Symbol” is planned for GCF production as of February 1, 2016 and has been available to test in INET OTF and GCF- EXT2 and EXT4 as of December 14, 2015. For the list of test instruments with longer symbol applied, please contact operator@nasdaq.com .
Details
Issuers An additional symbol field will be made available for issuer input. This additional symbol will be optional, will contain a maximum of 32 characters and must be unique. The current “Symbol” field continues as a required field and must also be unique.
Market participants and data feed customers Customers taking GCF/TIP-feed or reference data file from File Delivery Service (FDS) will see the longer entry in applicable cases (i.e. when longer symbol is provided by the issuer) within the “Symbol” field. Symbol already today has 32 characters. ITCH customers will continue to see the current symbol with maximum length of 16 characters.

GCF/TIP and ITCH:
S ymbols relayed over GCF/TIP (BasicDataTradable [BDt] - Symbol [SYm]) and ITCH (Order Book Directory - Symbol) can have different values. Please note that the ITCH symbol will not necessarily be a truncated version of the GCF/TIP symbol.
Instruments where the Symbol field can differ between ITCH and GCF have the below instrument type:
ITCH message = Order Book Directory, Field = Financial Product, Value = 8 = Warrant
GCF/TIP messages = Basic Data Derivative [BDDe], field = DerivativeType [Dty] 4 = Warrant
The recommended mapping is to match:
| ITCH | GCF/TIP | ||
| Table | Field | Table | Field |
| Order Book Directory | Order Book | Basic Data Tradable [BDt] | SourceId [Si] |
Protocol specifications
No protocol changes. No new field added in GCF/TIP for the longer symbol. Existing field “Symbol” will carry entries for the longer symbol in GCF/TIP, where this reference data has been provided by the issuer. “Symbol” field in GCF already today supports 32 characters.
Current versions of INET protocol specifications are available at the Nasdaq Nordic Technical Information website, under INET Nordic Protocol Specifications .
