I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    CHX proposes to amend Article 20, Rule 10 to amend its rules 
regarding clearly erroneous transactions. The text of this proposed 
rule change is available on the Exchange's Web site at http://
www.chx.com and in the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the CHX included statements 
concerning the purpose of and basis for the proposed rule changes and 
discussed any comments it received regarding the proposal. The text of 
these statements may be examined at the places specified in Item IV 
below. The CHX has prepared summaries, set forth in sections A, B and C 
below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Changes

1. Purpose
    The CHX is proposing to amend Article 20, Rule 10 regarding is 
handling of clearly erroneous trade executions. First, the Exchange 
proposes replacing existing paragraph (c)(2) of Rule 10, entitled 
``Unusual Circumstances and Joint Market Rulings'' with a new 
paragraph, entitled ``Multi-Stock Events Involving Twenty or More 
Securities.'' Second, the Exchange is replacing existing paragraph 
(c)(4) of Rule 10, entitled ``Numerical Guidelines Applicable to 
Volatile Market Opens'' with a new paragraph, entitled ``Individual 
Stock Trading Pauses.'' Third, the Exchange is proposing changes to 
existing paragraphs (f) and (g) of Rule 10 to eliminate the ability of 
the Exchange to deviate from the Numerical Guidelines contained in 
paragraph (c)(1) (other than under limited circumstances set forth in 
paragraph (f)) when deciding which transactions will be reviewed by the 
Exchange as potentially clearly erroneous. Finally, the Exchange 
proposes modifications to paragraphs (c)(1), (c)(3) and (e) of Rule 10 
consistent with the proposed changes to paragraphs (c)(2) and (c)(4). 
As proposed, the provisions of paragraphs (c), (e)(2), (f), and (g) of 
Rule 11.17, as amended pursuant to this filing, would be in effect 
during a pilot period set to end on December 10, 2010. If the pilot is 
not either extended or approved permanent by December 10, 2010, the 
prior versions of paragraphs (c), (e)(2), (f), and (g) of Rule 11.17 
would be in effect.
    The Exchange is proposing the rule changes described below in 
consultation with other markets and Commission staff to provide for 
uniform treatment: (1) Of clearly erroneous execution reviews in Multi-
Stock Events involving twenty or more securities; and (2) in the event 
transactions occur that result in the issuance of an individual stock 
trading pause by the primary market and subsequent transactions that 
occur before the trading pause is in effect on the Exchange. The 
Exchange has also proposed additional changes to Rule 10 that reduce 
the ability of the Exchange to deviate from the objective standards set 
forth in the Rule. The proposed changes are described in further detail 
below.
Revised Paragraph (c)(2) Related to Multi-Stock Events Involving Twenty 
or More Securities
    The Exchange proposes to eliminate the majority of existing 
paragraph (c)(2), which provides flexibility to the Exchange to use 
different Numerical Guidelines or Reference Prices in various ``Unusual 
Circumstances.'' The Exchange proposes to replace this paragraph with 
new language that would apply to Multi-Stock Events involving twenty or 
more securities whose executions occurred within a period of five 
minutes or less. The revised paragraph would retain language making 
clear that during Multi-Stock Events involving twenty or more 
securities the number of affected transactions may be such that 
immediate finality is necessary to maintain a fair and orderly market 
and to protect investors and the public interest. Accordingly, in such 
circumstances, decisions made by the Exchange in consultation with 
other markets could not be appealed. Further, as proposed, in 
connection with reviews of Multi-Stock Events involving twenty or more 
securities, the Exchange may use a Reference Price other than 
consolidated last sale in its review of potentially clearly erroneous 
executions. With the exception of those securities under review that 
are subject to an individual stock trading pause as described in 
proposed paragraph (c)(4), and to ensure consistent application across 
market centers when proposed paragraph (c)(2) is invoked, the Exchange 
will promptly coordinate with the other market centers to determine the 
appropriate review period, which may be greater than the period of five 
minutes or less that triggered application of proposed paragraph 
(c)(2), as well as select one or more specific points in time prior to 
the transactions in question and use transaction prices at or 
immediately prior to the one or more specific points in time selected 
as the Reference Price. The Exchange will nullify as clearly erroneous 
all transactions that are at prices equal to or greater than 30% away 
from the Reference Price in each affected security during the review 
period selected by the Exchange and other markets consistent with the 
proposed paragraph (c)(2).
    Because the Exchange and other market centers are adopting a 
different threshold and standards to handle large-scale market events, 
which would include events occurring during times of high volatility at 
the beginning of regular trading hours, the Exchange proposes deletion 
of paragraph (c)(4) (``Numerical Guidelines Applicable to Volatile 
Market Opens'') of the existing rule. The Exchange believes that this 
provision is no longer necessary, and if maintained, could result in 
extremely high Numerical Guidelines (up to 90%) in certain 
circumstances.
Revised Paragraph (c)(4) Related to Individual Stock Trading Pauses
    The primary listing markets for U.S. stocks recently amended their 
rules so that they may, from time to time, issue

[[Page 36744]]

a trading pause for an individual security if the price of such 
security moves 10% or more from a sale in a preceding five-minute 
period. In this regard, the Exchange recently amended its rules to 
pause trading in an individual stock when the primary listing market 
for such stock issues a trading pause in any Circuit Breaker 
Securities, as defined in Interpretation and Policy .06 of Rule 2 of 
Article 20.\3\ As described above, the Exchange is proposing to 
eliminate existing paragraph (c)(4) (``Numerical Guidelines Applicable 
to Volatile Market Opens''). The Exchange proposes adopting a rule, 
numbered as (c)(4) following such elimination, which will provide for 
uniform treatment of clearly erroneous execution reviews in the event 
transactions occur that result in the issuance of an individual stock 
trading pause by the primary listing market and subsequent transactions 
that occur before the trading pause is in effect on the Exchange. The 
proposed rule change is necessary to provide greater certainty of the 
clearly erroneous Reference Price for transactions that trigger a 
trading pause (the ``Trigger Trade'') and subsequent transactions 
occurring between the time of the Trigger Trade and the time the 
trading pause message is received by the Exchange from the single plan 
processor responsible for consolidation and dissemination of 
information for the security and put into effect on the Exchange, 
especially under highly volatile and active market conditions.
---------------------------------------------------------------------------

    \3\ See, CHX Article 20, Rule 2; see also Securities Exchange 
Act Release No. 62252 (June 10, 2010), 75 FR 34186 (June 16, 2010) 
(SR-CHX-2010-10).
---------------------------------------------------------------------------

    The Exchange proposes to revise paragraph (c)(4) of Rule 10 to 
allow the Exchange to use the price that triggered a trading pause in 
an individual stock (the ``Trading Pause Trigger Price'') as the 
Reference Price for clearly erroneous execution reviews of a Trigger 
Trade and transactions that occur immediately after a Trigger Trade but 
before a trading pause is in effect on the Exchange. As proposed, the 
phrase ``Trading Pause Trigger Price'' shall mean the price that 
triggered a trading pause in any Circuit Breaker Securities as defined 
in Interpretation and Policy .06 of Rule 2 of Article 20. The Trading 
Pause Trigger Price reflects a price calculated by the primary listing 
market over a rolling five-minute period and may differ from the 
execution price of a transaction that triggered a trading pause. The 
Exchange will rely on the primary listing market that issued an 
individual stock trading pause to determine and communicate the Trading 
Pause Trigger Price for such stock. The Exchange proposes to make clear 
in the text that the proposed standards in paragraph (c)(4) apply 
regardless of whether the security at issue is part of a Multi-Stock 
Event involving five or more securities as described in proposed 
paragraphs (c)(1) and (c)(2).
    As proposed, the Numerical Guidelines set forth in Rule 10(c)(1), 
other than those Numerical Guidelines applicable to Multi-Stock Events, 
would apply to reviews of Trigger Trades and subsequent transactions. 
The Exchange proposes to review, on its own motion pursuant to 
paragraph (g) of the Rule, all transactions that trigger a trading 
pause and subsequent transactions occurring before the trading pause is 
in effect on the Exchange. The Exchange has proposed to limit such 
reviews to reviews of transactions that executed at a price lower than 
the Trading Pause Trigger Price in the event of a price decline and 
higher than the Trading Pause Trigger Price in the event of a price 
rise. Because the proposed rules for trading pauses would only apply 
within the Regular Trading Session,\4\ an execution would be reviewed 
and nullified as clearly erroneous if it exceeds the following 
thresholds:
---------------------------------------------------------------------------

    \4\ The Regular Trading Session operates from 8:30 a.m. CT to 
3:00 p.m. CT. Article 20, Rule 1(b). According to rules of the 
primary listing markets, an individual stock trading pause can be 
issued based on a Trigger Trade that occurs at any time between 8:45 
a.m. and 2:35 p.m. CT. See, NASDAQ Rule 4120(a)(11), NYSE Rule 80C, 
and NYSE Arca Rule 7.11.

------------------------------------------------------------------------

Revisions to Paragraphs (f) and (g)
    Consistent with other proposals made in this filing, the Exchange 
proposes modifying paragraphs (f) and (g) to eliminate the ability of 
an Exchange official to deviate from the Numerical Guidelines contained 
in the Rule other than under very limited circumstances set forth in 
paragraph (f).
    Current paragraph (f) provides an officer of the Exchange or other 
senior level employee designee the ability on his or her own motion, to 
review and rule on executions that result from ``any disruption or a 
malfunction in the use or operation of any electronic communications 
and trading facilities of the Exchange, or extraordinary market 
conditions or other circumstances in which the nullification of 
transactions may be necessary for the maintenance of a fair and orderly 
market or the protection of investors and the public interest exist.'' 
Without modification, the language ``extraordinary market conditions or 
other circumstances * * * '' would leave the Exchange with broad 
discretion to deviate from the Numerical Guidelines set forth in 
paragraph (c)(1). Thus, the Exchange proposes narrowing the scope of 
paragraph (f) so that it only permits the Exchange to nullify 
transactions consistent with that paragraph (including at a lower 
Numerical Guideline) if there is a disruption or malfunction in the 
operation of the Exchange's system. For the same reason, the Exchange 
proposes eliminating the words ``use or'' from the language in 
paragraph (f) to make clear that the provision only applies to a 
disruption or malfunction of the Exchange's system (and not of an 
Exchange user's systems).
    Paragraph (g) gives an officer of the Exchange or other senior 
level employee designee the ability on his or her own motion to review 
transactions as potentially clearly erroneous. Consistent with the goal 
of achieving more objective and standard results, the Exchange proposes 
deleting language in existing paragraph (g) that would allow the 
Exchange to deviate from the Numerical Guidelines contained in 
paragraph (c)(1). In addition, the Exchange proposes to make clear that 
any Officer of the Exchange or other senior level employee reviewing 
transactions on his or her own motion must follow the guidelines set 
forth in proposed paragraph (c)(4), if applicable.

[[Page 36745]]

Accordingly, the Exchange proposes to modify paragraph (g) to state 
that an officer must rely on paragraphs (c)(1)-(4) of Rule 10 when 
reviewing transactions on his or her own motion.
Additional Conforming Revisions to Paragraphs (c)(1) and (c)(3) and (e)
    Based on proposed paragraph (c)(2), the Exchange has proposed 
certain conforming changes to paragraphs (c)(1), (c)(3) and (e) of the 
existing Rule, as described below. Under current Rule 10, a transaction 
may be found to be clearly erroneous only if the price of the 
transaction to buy (sell) that is the subject of the complaint is 
greater than (less than) the Reference Price by an amount that equals 
or exceeds the Numerical Guidelines set forth in paragraph (c)(1) of 
the Rule. The ``Reference Price'' is currently defined as ``the 
consolidated last sale immediately prior to the execution(s) under 
review except for in Unusual Circumstances as described in paragraph 
(c)(2)'' of Rule 10. The Exchange proposes modifying paragraph (c)(1) 
consistent with the changes described above such that the Exchange 
shall use the consolidated last sale immediately prior to the 
execution(s) under review as the Reference Price except for: (A) Multi-
Stock Events involving twenty or more securities, as described in 
proposed paragraph (c)(2); (B) transactions not involving a Multi-Stock 
Event as described in proposed paragraph (c)(2) that trigger a trading 
pause and subsequent transactions, as described in proposed paragraph 
(c)(4), in which case the Reference Price shall be determined in 
accordance with that paragraph (c)(4); and (C) in other circumstances, 
such as, for example, relevant news impacting a security or securities, 
periods of extreme market volatility, sustained illiquidity, or 
widespread system issues, where use of a different Reference Price is 
necessary for the maintenance of a fair and orderly market and the 
protection of investors and the public interest. The Exchange also 
proposes modifying paragraph (c)(1) to reduce uncertainty as to the 
applicability of the Numerical Guidelines, by requiring a finding that 
an execution was clearly erroneous if such execution exceeds the 
Numerical Guidelines, subject only to the Additional Factors included 
in paragraph (c)(3). Moreover, the Exchange proposes revising the 
existing description for Multi-Stock Events that is contained on the 
Numerical Guidelines chart to make clear that different Numerical 
Guidelines apply for Multi-Stock Events involving five or more, but 
less than twenty, securities whose executions occurred within a period 
of five minutes or less. In addition, the Exchange proposes adding to 
the Numerical Guidelines chart a row that contains the Numerical 
Guidelines (30%) for Multi-Stock Events involving twenty or more 
securities whose executions occurred within a period of five minutes or 
less.
    The Exchange proposes clarifying paragraph (c)(3) to make clear 
that the additional factors set forth in that paragraph are not 
intended to provide any discretion to an Exchange official to deviate 
from the guidelines that apply to Multi-Stock Events or to transactions 
in securities subject to individual stock trading pauses.
    Finally, the Exchange proposes amending paragraph (e)(2), related 
to appeals of clearly erroneous execution decisions by the Exchange, to 
preserve non-appealability of all joint rulings between the Exchange 
and one or more other market centers. The Exchange believes that 
certainty and consistency is critical to reviews of related executions 
that span multiple market centers. Accordingly, although the Exchange 
has proposed deletion of such language from existing paragraph (c)(3), 
the Exchange proposes adding such language back in to paragraph (e)(2) 
to make clear that joint market rulings are not appealable.
2. Statutory Basis
    Approval of the rule change proposed in this submission is 
consistent with the requirements of the Act and the rules and 
regulations thereunder that are applicable to a national securities 
exchange, and, in particular, with the requirements of Section 6(b) of 
the Act.\5\ In particular, the proposed change is consistent with 
Section 6(b)(5) of the Act,\6\ because it would promote just and 
equitable principles of trade, remove impediments to, and perfect the 
mechanism of, a free and open market and a national market system, and, 
in general, protect investors and the public interest. The proposed 
rule change is also designed to support the principles of Section 
11A(a)(1) \7\ of the Act in that it seeks to assure fair competition 
among brokers and dealers and among exchange markets. The Exchange 
believes that the proposed rule meets these requirements in that it 
promotes transparency and uniformity across markets concerning reviews 
of potentially clearly erroneous executions in various contexts, 
including reviews in the context of a Multi-Stock Event involving 
twenty or more securities and reviews resulting from a Trigger Trade 
and any executions occurring immediately after a Trigger Trade but 
before a trading pause is in effect on the Exchange. Further, the 
Exchange believes that the proposed changes enhance the objectivity of 
decisions made by the Exchange with respect to clearly erroneous 
executions.
