Technical Specification Changes Required – The format and content of Crossing Session 2 will be changing
Per NYSE Information Memo 11-6, CSII Baskets are not exempt from the Regulation SHO short sale price restrictions. As such, the content and record layout for submitting Crossing Session II has been updated. Market participants are now required to submit the execution time and price associated with CSII transactions and identify short- or short exempt-related trades within the basket. In addition, market participants will also be required to submit the same individual security information for NYSE Amex listed securities that is currently required for NYSE listed securities associated with a basket.
NYSE will support CSII submitting firms testing by enabling firms to submit their intended file submissions via email. All CSII file submitting firms must participate in testing and successfully submit a test file in the new format specified in the attached technical specification.
The planned timeline for incorporating these changes is as follows:
- Firm Testing Begins - 2/13/12
- Firm Testing Ends - 5/2/12
- Anticipated Production Rollout - 5/7/12
