The NYSE today will introduce NYSE Order Imbalances, a rich, new data product that will increase the transparency of the NYSE's daily open and close, the two most critical periods of the trading day.

The NYSE is pleased to announce that it will now rebate 100% of all market data revenue shared with FINRA members reported via the FINRA/NYSE Trade Reporting Facility (TRF) in Tape A (New York Stock Exchange), Tape B (American Stock Exchange) and Tape C (NASDQ Exchange) securities.

In support of the NYSE's Take/Provide billing structure, the Exchange is enhancing its trading system to clearly identify customer executions with new billing indicators. These indicators will be provided both in real time on CMS execution reports as well as in your Post Trade reports (Merged Order Log).

An enhancement has been implemented on the NYSE Euronext CMS testing platform that will enable member firms to test the Liquidity Take/Provide Billing Codes. For details and support information see the Member Firm Notification regarding New Execution Report Billing Indicators.

The NYSE has filed with the Securities and Exchange Commission to modify the current operational conditions that govern the way specialist's provide price improvement to an order. The Exchange expects that this amendment will prove beneficial for customers sending orders to the Exchange through added liquidity, increased price improvement frequency and even further decreased effective spreads.
