Beginning next Monday, November 23, 2009, customers of NYSE Euronext's U.S. cash equities markets will have access to a web-based service for submitting Clearly Erroneous Execution review requests. The new CEE submission process is designed to speed and simplify entry of review requests while helping customers meet the deadline for providing all the relevant execution information, which is typically 30 minutes after execution.

The New York Stock Exchange will implement changes to accept limit and stop orders priced less than $1 entered in sub-pennies for all securities listed on both the NYSE and NYSE Amex without rounding such prices to the nearest whole penny. Orders priced equal to or greater than $1 entered in sub-pennies will continue to be rejected, as is done today. Pursuant to Regulation NMS Rule 162, limit orders priced under $1 in increments smaller than .0001 will be rejected. Please refer to the attached link for additional technical details.

Previously, the NYSE announced its compliance with the 2008 SEC accord to support uniform symbology across all exchanges, along with availability for firms to test both four- and five-character root symbols in the User Acceptance Test (UAT) environment (see the December 2, 2008 Trader Update).

• "G" representing NYSE e-Broker hand-held interest routed away from the NYSE Trading Systems

Effective Monday, October 5, 2009, the NYSE is amending its Rule 128, entitled Clearly Erroneous Executions. The amended rule is the result of a coordinated effort among all national securities exchanges to improve the consistency of clearly erroneous execution rules at such exchanges and to add more objective criteria to be used in handling clearly erroneous executions. NYSE AMEX is adopting the same rule. Key components of the Rule are highlighted in the attached Information Memo.

Regulation Information Memo

In August of 2010, NYSE Euronext plans take the first steps in migrating trading of its US markets to its new, state-of-the-art data center. Construction of this facility is well underway and represents a significant investment by NYSE Euronext to provide our customers with a technology platform that can facilitate industry leading performance with greater security, flexibility and collocation opportunities.

As previously announced in the NYSE Trader Update of September 8, 2009, NYSE Amex is preparing to trade NASDAQ Listed Equities and selected ETFs on an Unlisted Trading Privilege basis starting on a date to be announced early in the first quarter of 2010.

Effective September 25, the On-line Comparison System (NYSE OCS ®) will be modified to require an Entering Firm, Branch/Sequence and Account Type on NYSE and NYSE Amex add transactions. In addition the "stamp" functionality will be disabled for OCS Clearing Firm users. In lieu of the "stamp" functionality, all Clearing Firm users should add their side of an execution to OCS to be matched against their contra party. These changes are being implemented to conform to NYSE Rules 123(e) and 123(f). Details of the processing for adds and stamps are contained in the two notices below.

NYSE Operations Memo

In response to member firm's requests, and as part of the NYSE’s deployment of the Super Display Book (SDBK), an expanded Account Field was implemented with plans to pass that tag back to firms on all CCG responses. As previously announced in the August 7, 2009 Trader Update, the NYSE will activate functionality to pass the Account Field back to firms on Monday, September 14, 2009.

On Saturday, October 24th, 2009, NYSE Euronext will be participating in the SIFMA industry-wide test in which all firms and exchanges are being asked to participate in a "mock disaster" by trading through their backup sites.

In addition to registration with SIFMA or any other market, NYSE Euronext is requesting that participating firms register for this test by contacting Chris Calcaterra at 888.689.7739. Registration must be done by Wednesday at 12 pm, October 21, 2009.

NYSE Euronext plans call for the NYSE to leave the trading floor closed and request that firms participating in this test trade through NYSE Arca. Firms submitting orders to the NYSE trading floor between the hours of 9:30 and 12:00 on Saturday, October 24th will get a “market closed” response.

NYSE Arca production systems will be used for the test; they will be up on Saturday, October 24, at 8 a.m. ET with an opening time of 9:30 a.m. ET and a closing time of 12 p.m. ET. To provide the most realistic environment for the test, we will bring up our NYSE Arca production system as we would for a normal production day. All Order entry, drop copy and ArcaBook sessions will be available for the test. All Listed, OTC, and Options symbols will be available for order entry.

Any firms that want to test connectivity to NYSE Arca can do so daily from 6am-8pm ET by calling the NYSE Arca connectivity support hotline (888) 689-7739

As previously communicated in the March 5, 2009 Trader Update and in the February 2, 2009 Trading Technology Information Memo, as part of the NYSE's deployment of the Super Display Book (SDBK) database and in response to member firm's requests, an expanded Account Field was implemented with plans to pass that tag back to firms on all CCG responses once the deployment was complete. The NYSE plans to complete deployment of the SDBK database on all NYSE and NYSE Amex securities by mid-August and will activate flags to pass the Account Field back to firms on Monday, September 14, 2009.

Effective August 1, 2009, the NYSE and NYSE Amex will implement pricing changes to the open and closing auctions as well as odd lots. Included in this price changes are:

• Reduced take rate of $0.0017, 32%-43% lower than other major exchanges, for qualified firms


• Odd-Lot pricing of $0.0018, still 28%-40% lower than taking on other major exchanges


• NYSE opening auction rate of $0.0005 with $10,000 monthly cap by firm


• NYSE and NYSE Amex closing auction rates of $0.0007

With over 3200 NYSE and 15 NYSE Amex securities migrated over to the new SDBK database, customers are reminded that the NYSE now supports order quantities up to 6.5 million shares for orders destined to SDBK. For symbols that have not yet been migrated, the maximum share quantity supported remains at 3 million. For all symbols, the maximum auto-execution size remains at 1 million shares and the maximum quantity supported by the Broker systems remains at 6.5 million shares.

For more information on the symbols that support the increased maximum quantity, please refer to the SDBK Security Rollout list maintained on the NYSE Equities Reference page.

Members and member organizations should be aware that certain orders and order-entry practices can improperly dislocate the market in a security, raising regulatory concerns.

June 1, 2009 – Trading in General Motors corporation and related securities will open on the Stock Exchange following the normal indication process. See below for additional NYSE Regulation, Inc. Information.

NYSE Regulation, Inc. (“NYSE Regulation”) announced today that it determined that the common stock of General Motors Corporation (the “Company”) – ticker symbol GM – as well as the 10 related listed securities below, should be suspended prior to the opening on June 2, 2009.

The New York Stock Exchange (NYSE) announces that the common and related structured products of General Motors Corporation (ticker symbol GM) will be halted news dissemination during the pre-market and available to all markets for trading at 9:30am (EST) on the morning of Monday, June 1, 2009.

As a clarification to the earlier Trader Update regarding 4 and 5 character symbol trading on the NYSE, the VALE.P symbol will appear as follows in the following NYSE inputs and outputs:

CCG: VALE P
CTS and CQS High Speed Lines: VALE/P
Slow Speed Ticker: VALE.P
Post Trade Output: VALEP

On December 2, 2008, the NYSE announced that in accord with the November 2008 SEC decision to have uniform symbology across exchanges, the NYSE would offer firms the ability to test four and five-character symbols at the NYSE (see the December 2, 2008 Trader Update). Effective Monday May 4, 2009, four symbols will trade on the NYSE as 4-character root symbols. Participants should ensure that their systems are prepared to handle these symbols.

To update the March 18, 2009 Trader Update post, in response to firms’ concerns regarding changes implemented in the initial pilot stock of the Super Display Book (SDBK) deployment, the NYSE will be implementing software changes to reinstate the Cancel Replace to reduce message type into the SDBK environment. The linked Trading Technology Information Memo details the implementation of the order type. This software enhancement will be available for firms to test in the User Acceptance Test (UAT) environment shortly.

Subsequent notification will be issued detailing the deployment of this software to additional pilot stocks.

Trading Technology Information Memo (March 27, 2009)
Current SDBK Securities Rollout List

To update the March 11, 2009 Trader Update post, NYSE Euronext successfully deployed its new Super Display Book (SDBK) database in production on Monday, March 16, 2009 in the stock Par Technologies Corporation (NYSE Listed: PTC) and confirmed processing through the comparison, clearing and settlement systems.

To update the March 5, 2009 Information Memo, NYSE Euronext will migrate one low volume NYSE cash equities symbol from the SuperDOT® (SDOT) databases to a newly implemented Super Display Book (SDBK) database in production on Monday, March 16, 2009. Trading in the pilot stock will take place through the settlement cycle and the systems will be adjusted as required before the stock symbol is announced and before any further rollout commences.

As previously communicated in the March 5, 2009 Information Memo, NYSE Euronext will be migrating NYSE and NYSE Amex cash equities from the SuperDOT® (SDOT) databases to a newly implemented Super Display Book (SDBK) database. Firms wishing to test their systems in the new SDBK database environment can do so in the User Acceptance Test (UAT) environment between the hours of 9:00 AM and 10:00 PM (with product support available between 9:00 AM and 5:00 PM).

The NYSE and NYSE Alternext US will begin decommissioning SuperDot® and migrating symbols to the new SDBK Database on a stock by stock basis. The NYSE anticipates that this migration will begin at month end, but will announce the Day 1 migration shortly. As part of that process, the NYSE and NYSE Alternext US will no longer accept orders with settlement terms of Cash, Next Day or Seller’s Option for those migrated stocks. Orders in those stocks containing these settlement terms will be rejected as an “Invalid Settlement Term.”

Effective tomorrow, Friday, February 6, 2009, the Exchange is implementing a single-print close designed to reduce the manual processing required of the DMM to close a security. As a result, the imbalance (if any) of paired-off closing transaction and stop orders elected for execution on the close will now be reported to the Tape as a single transaction and print.

The Exchange anticipates that consolidation of the separate transactions and prints will increase the efficiency of the closing process, resulting in speedier reporting of closing transactions.

Member firms were informed on January 20, 2009, that the NYSE completed the migration to the new Common Customer Gateway ^SM order entry system and will begin to implement Phase II of our systems upgrades.

This technical notice, dated February 2, 2009, provides the details for the functional enhancements being introduced as part of the stock migration to the new SDBK^SM Database. Current NYSE and NYSE Alternext US Equities Trading functionality remains, unless explicitly stated otherwise.

In addition, a SDBK FAQ has been included for your reference at end of this notification.

NYSE Euronext is in the process of constructing new data centers in the New York and London metropolitan areas. These facilities will replace the existing facilities currently operating in these areas. We anticipate that the consolidation into these new facilities will further enable NYSE Euronext to provide you with a broader offering of services including enhanced collocation capability.

On November 6, 2008, the SEC adopted a plan that will establish a uniform system for the selection and reservation of securities symbols. The result of this plan, which will become active 60 days from the above date, will mean that the allocation and use of symbols can be from one to five characters in length across all SROs. What this means for the New York Stock Exchange is the potential for NYSE Listed Companies to have a four- or five-character symbol as their ticker identifiers.

Beginning on December 1, 2008, the New York Stock Exchange will accept and no longer reject orders priced less than $1 that are entered in sub-pennies for all securities listed on both the NYSE and NYSE Alternext. The Exchange will round limit orders to the nearest next whole penny, either down for buy orders or up for sell orders, to represent the order for execution or to transmit the bid or offer to the Consolidated Quote System using the rounded limit price. Please refer to the two attached links for additional technical details and for the SEC Rule filing.

Additionally, at a date to be announced shortly, the Exchange systems will also begin passing back reports to clients in sub-pennies, with a maximum of a four decimal place increment for executions that are received from away market centers.

The NYSE announced today that SEC approvals have cleared the way for a Monday October 27th launch of the NYSE’s next-generation market model featuring advanced new trading tools supported by a revised rule set designed to maximize the NYSE's market quality and competitiveness in today's increasingly electronic trading environment. The rollout of the new Market Model will be released in phases.

Due to Amex Integration testing scheduled for October 25th, the industry wide regional contingency trading test, which was originally planned for Saturday, October 25th, 2008 is being postponed to Saturday, November 15, 2008 This exercise is being run so that NYSE Euronext and its member firms could test their business recovery capabilities should a contingency event occur that affects the New York Metropolitan area.
For information on how to register for the test as well as the specifics of connectivity requirements in a contingency environment, please see the NYSE Business Contingency Update Memo provided here.

NYSE Business Contingency Update Memo

Beginning on October 1, 2008, the Exchange is doubling the LRP ranges. By widening the current values, the Exchange is limiting the amount of time automatic execution is suspended, while continuing to provide protection from volatile order flow. This will allow for more continuous automatic executions of securities but continue to integrate the auction market to provide the opportunity for additional liquidity.

SEC Release No. 34-58588

The NYSE has lifted the news dissemination halt on Lehman Brothers allowing other markets, including NYSE Arca, to trade the security. Lehman will not open or trade on the NYSE.

The decision to lift the news dissemination halt was based on Lehman’s press release issued last night outlining Barclays agreement to acquire Lehman Brothers' North American investment banking and capital markets operations.

As previously reported, Standard & Poor’s has removed Lehman from their indices. For additional detail on the removal of Lehman from the S&P please go to the S&P website.

As previously reported, the Consolidated Trade System (CT) experienced problems this morning between the opening and approximately 9:38am. The system did not publish sales in Tape A securities (NYSE-listed) from any exchange in the security symbol range 'A' through 'L'. The New York Stock Exchange has provided to the Consolidated Tape System all of its opening prints in the affected symbols, and the Consolidated Tape System has added these prints to the tape with an 'N' exchange modifier, and an 'OPD' trade modifier (indicating an out-of-sequence, opening trade).

Please note that different vendors will process trades marked with 'OPD' differently for VWAP calculations. For example, Bloomberg may include these trades in its VWAP calculation while Thomson Reuters will not. If you have any questions regarding various VWAP calculations or other treatment of 'OPD' trades, please contact your market data vendor.
