OATS Expansion to all NMS Stocks

OATS for NMS Implementation Delayed to October, 17, 2011

Posted: September 27, 2011

FINRA intends to file with the SEC to delay the expansion of OATS to all NMS Stocks until October 17, 2011.  FINRA believes additional testing time for member firms will allow for any remaining implementation issues to be resolved before the new rule and related technical requirements become effective on October 17, 2011.  The same previously announced phase-in schedule will be followed but with dates moved back for the start of each phase by two weeks.
