What you need to know:

  • As announced in Equity Trader Alert #2010-1, NASDAQ OMX is introducing new technical specifications in preparation for industry listing and trading of 5-character root symbols.
  • NASDAQ OMX has created new NASDAQ and BX order entry, clearing and market data specifications.
  • Firms are required to be ready for the new specifications and prepare their systems by Monday, May 3, 2010.

Why is NASDAQ OMX modifying equity technical specifications?

Many technical specifications for The NASDAQ Stock Market® and NASDAQ OMX BXSM (BXSM) have fixed-length 6-character fields for the ticker symbol (root plus suffix). NASDAQ OMXSM has created new specifications to accommodate symbol sizes of up to 8 characters to in response to the New York Stock Exchange’s intention to begin listing and trading companies using 5-character root symbols exclusive of any symbol suffix as announced in Equity Trader Alert #2010-1.

How should my firm prepare for the equity symbology changes?

Firms must obtain the updated technical specifications from the NASDAQ OMX Trader® website and prepare their systems to accept the changes prior to Monday, May 3, 2010.
