Chicago Board Options Exchange, Incorporated Rules

* * * * *

Rule 1.1. Definitions

    When used in these Rules, unless the context otherwise requires:
    (a)-(yyy) No change.

National Spread Market

    (zzz) ``National spread market'' is the derived net market based 
on the NBBOs in the individual series legs comprising a complex 
order and, if a stock-option order, the NBBO of the stock leg.

Exchange Spread Market

    (aaaa) ``Exchange spread market'' is the derived net market 
based on the BBOs in the individual series legs comprising a complex 
order and, if a stock-option order, the NBBO of the stock leg.

Rule 6.12. CBOE Hybrid Order Handling System

    This rule describes the process for routing orders through the 
Exchange's order handling system in classes designated for trading 
on the CBOE Hybrid System. The order handling system is a feature 
within the Hybrid System to route orders for automatic execution, 
book entry, open outcry, or further handling by a broker, agent, or 
PAR Official, in a manner consistent with Exchange Rules and the Act 
(e.g., resubmit the order to the Hybrid System for automatic 
execution, route the order from a booth to a PAR workstation, cancel 
the order, contact the customer for further instructions, and/or 
otherwise handle the order in accordance with Exchange Rules and the 
order's terms).
    (a) Orders may route through the order handling system for 
electronic processing in the Hybrid System or to a designated order 
management terminal or PAR Workstation in any of the circumstances 
described below. Routing designations may be established based on 
various parameters defined by the Exchange, order entry firm or 
Trading Permit Holder, as applicable.
    (1)-(3) No change.
    (4) Limit Order Price Parameter for Complex Orders: [Limit 
orders will route directly from an order entry firm to an order 
management terminal designated by the order entry firm if]The System 
rejects back to a Trading Permit Holder a complex limit order with a 
net debit (credit) price more than a specified amount above (below):

[[Page 13679]]

    (i) prior to the opening (including during any pre-opening 
period and opening rotation)[before a series is opened following a 
halt), the order is priced at a net debit that is more than an 
acceptable tick distance above] the derived net market using the 
Exchange's previous day's closing[e] prices in the individual series 
legs comprising the complex order. However, this does not apply[ or 
the order is priced at a net credit that is more than an acceptable 
tick distance below the derived net market using the Exchange's 
previous day's close in the individual series legs comprising the 
complex order (this subparagraph is not applicable] to stock-option 
orders, [or]to orders for the account of Exchange Market-Makers or 
away Market-Makers[)], or if there is no Exchange previous day's 
closing price in any leg; or
    (ii) [once a series has opened, the order is priced at a net 
debit that is more than an acceptable tick distance above]intraday, 
the opposite side of the national spread [derived net ]market. This 
applies to stock-option orders, but does not apply [using the 
Exchange's best bid or offer in the individual series legs 
comprising the complex order or the order is priced at a net credit 
that is more than an acceptable tick distance below the opposite 
side derived net market based on the individual series legs 
comprising the complex order (this subparagraph is not applicable to 
stock-option orders)]if the NBBO in any leg is locked, crossed or 
unavailable or if there is no Exchange spread market.
    For purposes of this subparagraph (a)(4), [: An ``acceptable 
tick distance'' (which is also referred to as an ``ATD''), as 
determined by] the Exchange determines the amount, which may be no 
less than $0.02, on a class-[ ]by-[ ]class and net premium basis and 
announce[d]s the amount to [the ]Trading Permit Holders via 
Regulatory Circular[, shall be no less than 5 minimum net price 
increment ticks for complex orders]. The Exchange may determine to 
apply a different amount to orders entered during the pre-opening or 
a trading rotation. No limit order price parameter applies to 
complex orders submitted during a halt (including during any pre-
opening period and opening rotation prior to re-opening following 
the halt) or to pairs of orders submitted to AIM and SAM. The 
[Exchange may determine on a class by class basis and announce via 
Regulatory Circular whether to apply paragraphs (a)(4)(i) and/or 
(ii) to immediate-or-cancel complex orders]checks in subparagraphs 
(i) and (ii) do not apply to complex orders routed from a PAR 
workstation or order management terminal, or to multi-class spreads. 
The limit order price parameter will take precedence over another 
routing parameter to the extent that both are applicable to an 
incoming limit order.
    (5) [Limit Order Price Parameter for Stock-Option Orders: Limit 
orders received after a series is opened will be cancelled if the 
order is priced at a net debit that is more than an acceptable tick 
distance above the opposite side derived net market using the 
Exchange's best bid or offer in the individual series leg and the 
national best bid or offer of the stock component comprising the 
stock-option order or the order is priced at a net credit that is 
more than an acceptable tick distance below the opposite side 
derived net market based on the Exchange's best bid or offer in the 
individual series leg and the national best bid or offer of the 
stock component comprising the stock-option order.
    For purposes of this subparagraph (a)(5): An ``acceptable tick 
distance'' (which is also referred to as an ``ATD''), as determined 
by the Exchange on a class by class and net premium basis and 
announced to the Trading Permit Holders via Regulatory Circular, 
shall be no less than 5 minimum net price increment ticks for stock-
option orders. The Exchange may determine on a class by class basis 
and announce via Regulatory Circular whether to apply paragraph 
(a)(5) to immediate-or-cancel complex orders. The limit order price 
parameter will take precedence over another routing parameter to the 
extent that both are applicable to an incoming limit 
order.]Reserved.
    (6)-(7) No change.
    (b) No change.
    . . . Interpretations and Policies:
    .01 For purposes of subparagraphs (a)(3)[,] and (4)[ and (5):], 
the senior official on the Exchange Help Desk or two Floor Officials 
may grant [intra-day ]relief on any trading day (including prior to 
opening) by widening or inactivating one or more of the applicable 
[ATD]amount parameter settings in the interest of a fair and orderly 
market.
    (a) Notification of [intra-day]this relief will be announced as 
soon as reasonably practical via verbal message to the trading 
floor, order management terminal message to TPH organizations on the 
trading floor, and electronic message to Trading Permit Holders that 
request to receive such messages. Such [intra-day ]relief will not 
extend beyond the trade day on which it is granted, unless a 
determination to extend such relief is announced to Trading Permit 
Holders via Regulatory Circular. The Exchange will make and keep 
records to document all determinations to grant [intra-day]this 
relief under this Rule, and shall maintain those records in 
accordance with Rule 17a-1 under the Exchange Act.
    (b) The Exchange will periodically review determinations to 
grant [intra-day ]relief on any trading day for consistency with the 
interest of a fair and orderly market.
* * * * *

Rule 6.53C. Complex Orders on the Hybrid System

    (a)-(c) No change.
    (d) Process for Complex Order RFR Auction: Prior to routing to 
the COB or once on PAR, eligible complex orders may be subject to an 
automated request for responses (``RFR'') auction process.
    (i) No change.
    (ii) Initiation of a COA:
    (A) The System will send an RFR message to all Trading Permit 
Holders who have elected to receive RFR messages on receipt of (1) a 
COA-eligible order with two legs (including orders submitted for 
electronic processing from PAR) that is better than the same side of 
the [derived net]Exchange spread market or (2) a complex order with 
three or more legs that (A) meets the class, size, and complex order 
type parameters of subparagraph (d)(i)(2) and is better than the 
same side of the [derived net]Exchange spread market or (B) is 
marketable against the [derived net]Exchange spread market, 
designated as immediate or cancel and meets the class and size 
parameters of subparagraph (d)(i)(2). Complex orders as described in 
subparagraph (ii)(A)(2) will initiate a COA regardless of the 
order's routing parameters or handling instructions (except for 
orders routed for manual handling). Immediate or cancel orders that 
are not marketable against the [derived net]Exchange spread market 
in accordance with subparagraph (ii)(A)(2)(B) will be cancelled. The 
RFR message will identify the component series, the size and side of 
the market of the COA-eligible order and any contingencies, if 
applicable.
    (B) No change.
    (iii)-(ix) No change.
    . . . Interpretations and Policies:
    .01-.03 No change.
    .04 For each class where COA is activated, the Exchange may also 
determine to activate COA for complex orders resting in COB. For 
such classes, any non-marketable order resting at the top of COB may 
be automatically subject to COA if the order is within a number of 
ticks away from the opposite side of the current [derived 
net]Exchange spread market. [The ``derived net market'' will be 
calculated based on the derived net price of the individual series 
legs. For stock-option orders, the derived net market for a strategy 
will be calculated using the Exchange's best bid or offer in the 
individual option series leg(s) and the NBBO in the stock leg.] The 
Exchange may also determine on a class-by-class and strategy basis 
to limit the frequency of COAs initiated for complex orders resting 
in COB. Notwithstanding the foregoing, if a leg order has been 
generated for a complex order resting in the COB pursuant to 
paragraph (c)(iv) of this Rule, the complex order will not be 
eligible for COA.
    .05-.07 No change.
    .08 Price Check Parameters: On a class-by-class basis, the 
Exchange may determine (and announce to the Trading Permit Holders 
via Regulatory Circular) which of the following price check 
parameters will apply to eligible complex orders. Paragraph[s] (b) 
[and (e)] will not be applicable to stock-option orders.
    For purposes of this Interpretation and Policy .08:
    Vertical Spread. A ``vertical'' spread is a two-legged complex 
order with one leg to buy a number of calls (puts) and one leg to 
sell the same number of calls (puts) with the same expiration date 
but different exercise prices.
    Butterfly Spread. A ``butterfly'' spread is a three-legged 
complex order with two legs to buy (sell) the same number of calls 
(puts) and one leg to sell (buy) twice as many calls (puts), all 
with the same expiration date but different exercise prices, and the 
exercise price of the middle leg is between the exercise prices of 
the other legs. If the exercise price of the middle leg is halfway 
between the exercise prices of the other legs, it is a ``true'' 
butterfly; otherwise, it is a ``skewed'' butterfly.
    Box Spread. A ``box'' spread is a four-legged complex order with 
one leg to buy

[[Page 13680]]

calls and one leg to sell puts with one strike price, and one leg to 
sell calls and one leg to buy puts with another strike price, all of 
which have the same expiration date and are for the same number of 
contracts.
    To the extent a price check parameter is applicable, the 
Exchange will not automatically execute an eligible complex order 
that is:
    (a)-(d) No change.
    (e) Acceptable Percentage [Distance]Range Parameter:
    (i) An incoming complex order (including a stock-option order) 
after the series for all legs of the complex order are open for 
trading that is marketable and would execute immediately upon 
submission to the COB or following a COA if[, following COA,] the 
execution would be at a price [that is not within]outside an 
acceptable percentage [distance from the derived net price of the 
individual series legs ]range. The ``acceptable percentage range'' 
is the national spread market (or Exchange spread market if the NBBO 
in any leg is locked, crossed or unavailable and for pairs of orders 
submitted to AIM or SAM) that existed when the System received the 
order or at the start of the COA[. The ``acceptable percentage 
distance'' will be a percentage determined by the Exchange on a 
class-by-class basis and it shall be not less than 3 percent. Such a 
complex order will route via the order handling system pursuant to 
Rule 6.12.], as applicable, plus/minus:
    (A) the amount equal to a percentage (which may not be less than 
3%) of the national spread market (the ``percentage amount'') if 
that amount is not less than a minimum amount or greater than a 
maximum amount (the Exchange will determine the percentage and 
minimum and maximum amounts and announce them to Trading Permit 
Holders by Regulatory Circular);
    (B) the minimum amount, if the percentage amount is less than 
the minimum amount; or
    (C) the maximum amount, if the percentage amount is greater than 
the maximum amount.
    (ii) The System cancels an order (or any remaining size after 
partial execution of the order) that would execute or rest in the 
COB at a price outside the acceptable price range.
    (iii) If the System rejects either order in a pair of orders 
submitted to AIM or SAM pursuant to this parameter, then the System 
also cancels the paired order. Notwithstanding the foregoing, with 
respect to an AIM Retained (``A:AIR'') order as defined in 
Interpretation and Policy .09 to Rule 6.74A, if the System rejects 
the Agency Order pursuant to this check, then the System also 
rejects the contra-side order; however, if the System rejects the 
contra-side order pursuant to this check, the System still accepts 
the Agency Order if it satisfies the check. To the extent a contra-
side order or response is marketable against the Agency Order, the 
execution price will be capped at the opposite side of the 
acceptable price range.
    (f) [Stock-Option Derived Net Market Parameters: A stock-option 
order that is marketable if, following COA, the execution would not 
be within the acceptable derived net market for the strategy that 
existed at the start of COA.
    (1) An ``acceptable derived net market'' for a strategy will be 
calculated using the Exchange's best bid or offer in the individual 
option series leg(s) and the NBBO in the stock leg plus/minus an 
acceptable tick distance. An ``acceptable tick distance'' will be 
determined by the Exchange on a class-by-class and premium basis.
    (2) Such a stock-option order will route via the order handling 
system pursuant to Rule 6.12.
    In classes where this price check parameter is available, it 
will also be available for COA responses under Rule 6.53C(d), AIM 
and Solicitation Auction Mechanism stock-option orders and responses 
under Rule 6.74A and 6.74B, and customer-to-customer immediate cross 
stock-option orders under Rule 6.74A.08. Under these provisions, 
such paired stock-option orders and responses will not be accepted 
except that, to the extent that only a paired contra-side order 
subject to an auction under Rule 6.74A or 6.74B exceeds this price 
check parameter, the contra-side order will not be accepted and the 
paired original Agency Order will not be accepted or, at the order 
entry firm's discretion (i.e. an AIM Retained (``A:AIR'') order, as 
defined in Interpretation and Policy .09 to Rule 6.74A), continue 
processing as an unpaired stock-option order. To the extent that a 
contra-side order or response is marketable, its price will be 
capped at the price inside the acceptable derived net 
market.]Reserved.
    (g) No change.
    .09-.10 No change.
    .11 Execution of Complex Orders on the COB Open:
    (a) Complex orders, including stock-option orders, do not 
participate in opening rotations for individual component option 
series legs conducted pursuant to Rule 6.2B. When the last of the 
individual component option series legs that make up a complex order 
strategy has opened (and, in the case of a stock-option order, the 
underlying stock has opened), the COB for that strategy will open. 
The COB will open with no trade, except as follows:
    (i) The COB will open with a trade against the individual 
component option series legs if there are complex orders on only one 
side of the COB that are marketable against the opposite side of the 
[derived net]Exchange spread market. The resulting execution will 
occur at the [derived net]Exchange spread market price to the extent 
marketable pursuant to the rules of trading priority otherwise 
applicable to incoming electronic orders in the individual component 
legs. To the extent there is any remaining balance, the complex 
orders will trade pursuant to subparagraph (ii) below or, if unable 
to trade, be processed as they would on an intra-day basis under 
Rule 6.53C. This subparagraph (i) is not applicable to stock-option 
orders because stock-option orders do not trade against the 
individual component option series legs when the COB opens.
    (ii) The COB will open (or continue to open with another trade 
if a trade occurred pursuant to subparagraph (i) above) with a trade 
against complex orders if there are complex orders in the COB 
(including any remaining balance of an order that enters the COB 
after a partial trade with the legs pursuant to subparagraph (i)) 
that are marketable against each other and priced within the 
[derived net]Exchange spread market. The resulting execution will 
occur at a market clearing price that is inside the [derived 
net]Exchange spread market and that matches complex orders to the 
extent marketable pursuant to the electronic allocation algorithm 
from Rule 6.45A or 6.45B, as applicable, as determined by the 
Exchange on a class-by-class basis with the addition that the COB 
gives priority to complex orders whose net price is better than the 
market clearing price first, and then to complex orders at the 
market clearing price. To the extent there is any remaining balance, 
the complex orders will be processed as they would on an intra-day 
basis under Rule 6.53C. This subparagraph (ii) is applicable to 
stock-option orders.
    (b) [The ``derived net market'' for a stock-option order 
strategy will be calculated using the Exchange's best bid or offer 
in the individual option series leg(s) and the NBBO in the stock 
leg. The ``derived net market'' for any other complex order strategy 
will be calculated using the Exchange's best bid or offer in the 
individual option series legs.
    (c) ]The Exchange may also use the process described in 
paragraph (a) of this Interpretation and Policy .11 when the COB 
reopens a strategy after a time period during which trading of that 
strategy was unavailable.
    .12 No change.

    The text of the proposed rule change is also available on the 
Exchange's Web site (http://www.cboe.com/AboutCBOE/CBOELegalRegulatoryHome.aspx), at the Exchange's Office of the 
Secretary, and at 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 Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange 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 Change

1. Purpose
    The Exchange has in place various price protection mechanisms that 
are designed to prevent complex orders from executing at potentially 
erroneous

[[Page 13681]]

prices.\5\ These mechanisms are designed to help maintain a fair and 
orderly market by mitigating potential risks associated with complex 
orders trading at prices that are extreme or potentially erroneous. 
Currently, certain of these price protection mechanisms applicable to 
complex orders compare a complex order's net price, or the net price at 
which a complex order would execute, against the derived net market 
price based on the Exchange's best bid or offer (``BBO'') in the 
individual series legs.\6\ The Exchange proposes to amend these 
mechanisms to provide they will use the derived net market based on the 
national best bid or offer (``NBBO'') in the individual series legs 
rather than the BBO. The Exchange also proposes to update the parameter 
that requires a complex order to execute at a range within an 
acceptable percentage distance from the current market.
---------------------------------------------------------------------------

    \5\ See, e.g., Rules 6.12(a)(4) and 6.53C, Interpretation and 
Policy .08.
    \6\ See id.
---------------------------------------------------------------------------

Limit Order Price Parameter for Complex Orders
    The proposed rule change amends the limit order price parameters 
for complex and stock-option orders, which are intended to block 
executions at prices that exceed the derived net market by more than a 
reasonable amount. Rule 6.12(a)(4) currently provides complex limit 
orders will route directly from an order entry firm to an order 
management terminal designated by the order entry firm if:
     prior to the opening (including before a series is opened 
following a halt), the order is priced at a net debit that is more than 
an acceptable tick distance above the derived net market using the 
Exchange's previous day's close in the individual series legs 
comprising the complex order or the order is priced at a net credit 
that is more than an acceptable tick distance below the derived net 
market using the Exchange's previous day's close in the individual 
series legs comprising the complex order \7\; or
---------------------------------------------------------------------------

    \7\ This provision currently does not apply to stock-option 
orders or orders for the account of Exchange Market-Makers or away 
Market-Makers.
---------------------------------------------------------------------------

     once a series has opened, the order is priced at a net 
debit that is more than an acceptable tick distance above the opposite 
side derived net market using the Exchange's best bid or offer in the 
individual series legs comprising the complex order or the order is 
priced at a net credit that is more than an acceptable tick distance 
below the opposite side derived net market based on the individual 
series legs comprising the complex order.
    For purposes of current subparagraph (a)(4), an ``acceptable tick 
distance'' (or ``ATD''), as determined by the Exchange on a class-by-
class and net premium basis and announced to Trading Permit Holders by 
regulatory circular, will be no less than 5 minimum net price increment 
ticks for complex orders. The Exchange may determine on a class-by-
class basis and announce by Regulatory Circular whether to apply the 
limit price parameters in subparagraph (a)(4)(i), (ii), or both, to 
immediate-or-cancel complex orders. This price parameter takes 
precedence over other routing parameters to the extent that both are 
applicable to an incoming limit order.
    Rule 6.12(a)(5) currently provides that stock-option limit orders 
received after a series is opened will be cancelled if the order is 
priced at a net debit that is more than an acceptable tick distance 
above the opposite side derived net market using the Exchange's best 
bid or offer in the individual series leg and the national best bid or 
offer of the stock component comprising the stock-option order or the 
order is priced at a net credit that is more than an acceptable tick 
distance below the opposite side derived net market based on the 
Exchange's best bid or offer in the individual series leg and the 
national best bid or offer of the stock component comprising the stock-
option order. For purposes of current subparagraph (a)(5), an ATD, as 
determined by the Exchange on a class-by-class basis and net premium 
basis and announced to the Trading Permit Holders by regulatory 
circular, will be no less than five minimum net price increment ticks 
for stock-option orders. The Exchange may determine on a class-by-class 
basis and announce by regulatory circular whether to apply subparagraph 
(a)(5) to immediate-or-cancel complex orders. This price parameter 
takes precedence over another [sic] routing parameters to the extent 
that both are applicable to an incoming limit order.
    The Exchange proposes to amend these provisions to provide a 
complex order's price generally will be compared to the derived net 
price based on the national spread market.\8\ Specifically, proposed 
subparagraph (a)(4) states the System rejects back to a Trading Permit 
Holder a complex limit order with a net debit (credit) price more than 
distance specified amount above (below): \9\
---------------------------------------------------------------------------

    \8\ The proposed rule change adds the definition of national 
spread market to proposed Rule 1.1(zzz), defined as the derived net 
market based on the NBBOs in the individual series legs comprising a 
complex order and, if a stock-option order, the NBBO of the stock 
leg.
    \9\ Additionally, under the proposed rule change to subparagraph 
(a)(4), the System rejects the order rather than routes it via the 
order handling system. This will allow the Trading Permit Holder to 
reevaluate the order price based on current market prices and ensure 
it was not erroneous, which the Exchange understands Trading Permit 
Holders often prefer (under current subparagraph (a)(5), the System 
currently cancels stock-option orders that do not satisfy the limit 
order price parameter). This is also consistent with functionality 
of various other price protections and risk controls, which reject 
orders rather than route them via the order handling system. See, 
e.g., Rule 6.53C, Interpretation and Policy .08(c) and (g).
---------------------------------------------------------------------------

     prior to the opening of a series (including during any 
pre-opening period and opening rotation), the derived net market using 
the Exchange's previous day's closing prices in the individual series 
legs comprising the complex order. However, this does not apply to 
stock-option orders, to orders of CBOE or away market-makers, or if 
there is no Exchange previous day's closing price in any leg; or
     intraday, the opposite side of the national spread market. 
This applies to stock-option orders, but does not apply if the NBBO in 
any leg is locked, crossed or unavailable \10\ or if there is no 
national spread market or no Exchange spread market.

    \10\ If the NBBO (or BBO) is not currently being disseminated, 
the NBBO (or BBO) will be considered ``unavailable.''
---------------------------------------------------------------------------

While the Exchange believes Trading Permit Holders are generally 
willing to accept executions at prices that exceed the maximum possible 
value of the applicable spread to a certain extent, executions too far 
away from the market may be erroneous. The current limit order price 
parameter when trading is open compares the order prices to the 
Exchange spread market,\11\ which is the derived net market based on 
the BBOs of the individual series legs comprising a complex order and, 
if a stock-option order, the NBBO of the stock leg. The proposed rule 
change amends this parameter so it compares an order's price to the 
national spread market intraday (i.e. when open for trading). As 
discussed above, the NBBO of the legs (upon which the national spread 
market is based) more accurately reflects the entire market for the 
legs comprising a complex order at the time of execution

[[Page 13682]]

than the Exchange spread market (based on the BBO of the legs). 
Therefore, the Exchange believes it is appropriate for complex order 
net execution prices during the trading day to be based on the best 
prices throughout the entire market rather than those only on CBOE's 
market.\12\
---------------------------------------------------------------------------

    \11\ The proposed rule change adds the definition of Exchange 
spread market to proposed Rule 1.1(aaaa), defined as the derived net 
market based on the BBOs in the individual series legs comprising a 
complex order and, if a stock-option order, the NBBO of the stock 
leg. The proposed rule change makes corresponding changes to Rules 
6.53C(d)(ii)(A) and Interpretations and Policies .04 and .11 to 
incorporate the proposed defined term (as well as delete the 
definition currently in those provision [sic] to avoid duplication). 
The proposed rule change also clarifies in Interpretation and Policy 
.04 the number of ticks is applied to the opposite side of the 
Exchange spread market, which is consistent with System 
functionality and language in other rules that incorporate the 
Exchange spread market or national spread market.
    \12\ The proposed rule change also makes nonsubstantive changes 
to subparagraph (a)(4).
---------------------------------------------------------------------------

    Prior to individual series legs opening on CBOE (which the rule 
clarifies includes any pre-opening period and opening rotation \13\), 
the System will continue to use the derived net market using the 
Exchange's previous day's closing prices as the comparison figure. The 
check will continue to not apply to stock-option orders or orders of 
CBOE or away market-makers. The check will also not apply if there is 
no Exchange previous day's closing price in any leg (and thus no 
reliable measure against which to compare the price of the order to 
determine its reasonability).
---------------------------------------------------------------------------

    \13\ Pursuant to Rule 6.2B, the procedure used to open classes 
for trading on the Exchange includes use of a pre-opening period 
(which currently begins at 6:30 a.m. for Regular Trading Hours and 
4:00 p.m. on the previous trading day for Extended Trading Hours) 
and trading rotation. The pre-opening period and rotation occur 
prior to a class being open, and the proposed rule change merely 
makes this clear.
---------------------------------------------------------------------------

    With respect to complex orders entered during a trading halt (which 
includes any pre-opening period or opening rotation prior to re-opening 
following a halt),\14\ current subparagraph (4)(i) applies, using the 
derived net market using the Exchange's previous day's closing prices. 
The proposed rule change states in subparagraph (4) the System will no 
longer apply the limit order price parameter to complex orders entered 
during a trading halt. If a halt occurs during the trading day, it is 
difficult for the System at this time to determine reliable pricing for 
each leg during a likely volatile time when quotes may be available for 
some legs but not others. The Exchange believes this is preferable to 
applying the check using the previous day's closing price, which would 
be stale by that time.
---------------------------------------------------------------------------

    \14\ Pursuant to Rule 6.2B(f), the Exchange may reopen a class 
following a trading halt using the procedure described in the rule, 
including use of a pre-opening period and rotation. Any such pre-
opening period and rotation would occur while trading is still 
halted, as trading would not yet be reopened, and the proposed rule 
change merely makes this clear.
---------------------------------------------------------------------------

    The proposed rule change states this price parameter will not apply 
to pairs of orders submitted to AIM or SAM. The AIM and SAM 
functionality separately limits the prices at which those pairs may be 
submitted and executed, and thus it would be duplicative for the System 
to apply this price parameter to those pairs of orders.\15\
---------------------------------------------------------------------------

    \15\ See Rules 6.74A(a) and Interpretation and Policy .07, and 
6.74B(a) and Interpretation and Policy .01, respectively.
---------------------------------------------------------------------------

    Once a series has opened on CBOE, this check will compare the price 
of a complex order with a net debit (credit) price to the opposite side 
of the national spread market. The national spread market would more 
accurately reflect the then-current market, rather than the Exchange 
spread market, and thus the Exchange believes it would be a better 
measure to use for purposes of determining the reasonability of the 
prices of orders. This applies to stock-option orders, but does not 
apply if the NBBO in any leg is locked, crossed or unavailable \16\ or 
if there is no Exchange spread market \17\ (and thus no reliable 
measure against which to compare the price of the order to determine 
its reasonability).
---------------------------------------------------------------------------

    \16\ If the NBBO (or BBO) is not currently being disseminated, 
the NBBO (or BBO) will be considered ``unavailable.''
    \17\ The Exchange notes this is consistent with functionality 
today--the System does not apply the limit order price parameter to 
an order if there is no Exchange spread market (which includes if 
there is no CBOE-disseminated quote in any leg comprising the 
complex order).
---------------------------------------------------------------------------

    Current subparagraph (a)(4)(i) does not apply to stock-option 
orders, and proposed subparagraph (a)(4)(i) will continue to not apply 
to stock-option orders. However, current subparagraph (a)(4)(ii) also 
does not apply to stock-option orders, and current subparagraph (a)(5) 
applies to stock-option orders. However, the limit order price 
parameter in current subparagraph (a)(4)(ii) applies to complex orders 
other than stock-option orders in the same manner as current 
subparagraph (a)(5) applies to stock-option orders using the Exchange 
spread market as the comparison figure.\18\ Following the proposed rule 
change, the limit order price parameter will apply to stock-option 
orders and other complex orders in the same manner using the National 
Spread Market. Therefore, the proposed rule change states that in the 
rules and also deletes subparagraph (a)(5) as it would be duplicative. 
The proposed rule change amends Rule 6.12, Interpretation and Policy 
.01 to delete the cross-reference to subparagraph (5), which is being 
deleted.
---------------------------------------------------------------------------

    \18\ The one difference is, under subparagraph (a)(5), the 
System cancels stock-option orders that do not satisfy the price 
parameter while, under subparagraph (a)(4)(ii), the System routes 
for manual handling complex orders that do not satisfy the price 
parameter. As discussed above, under proposed subparagraph 
(a)(4)(ii), the System will reject complex orders and stock-option 
orders that do not satisfy the price parameter.
---------------------------------------------------------------------------

    The rule currently states the Exchange determines the ATD on a 
class-by-class and premium basis and will be no less than five minimum 
increment ticks. The proposed rule change states the Exchange will 
determine a specified amount, rather than an ATD, which may be no less 
than $0.02. With respect to complex orders, the Exchange has determined 
pursuant to Rule 6.42(4) the minimum increment for complex orders in 
all but three classes (SPX, OEX and XEO) is $0.01, which would be the 
minimum increment tick under current Rule 6.12(a)(4) (thus the current 
minimum is essentially $0.01 for almost all classes). The Exchange 
generally announces the setting for this parameter in a monetary amount 
rather than number of ticks, so the Exchange believes amending the rule 
to use the term amount rather than ticks is consistent with this 
practice.\19\
---------------------------------------------------------------------------

    \19\ See Regulatory Circular RG17-013.
---------------------------------------------------------------------------

    Additionally, because market conditions during pre-opening periods 
and trading rotations \20\ are different than those present during 
regular trading hours, the proposed rule change provides the Exchange 
with flexibility to apply a different amount during those times. The 
Exchange believes it is appropriate to have the ability to apply a 
different amount during the pre-open period or opening rotation so the 
check does not impact the Exchange's ability to open an option or 
determination of the opening price.\21\
---------------------------------------------------------------------------

    \20\ Pursuant to Rule 6.1A(i), the Exchange may make a 
determination for Extended Trading Hours different from that made 
for Regular Trading Hours to the extent the rules allow the Exchange 
to make a determination, including on a class-by-class basis. Thus, 
the Exchange may set a different amount for classes trading during 
Extended Trading Hours than the amount set for those classes during 
Regular Trading Hours.
    \21\ Note current Rule 6.12, Interpretation and Policy .01 
permits a senior official on the Exchange Help Desk or two Floor 
Officials to grant intra-day relief by widening or inactivating one 
or more of the applicable ATD parameters settings in the interest of 
a fair and orderly market. The proposed rule change amends 
Interpretation and Policy .01 to provide this relief (with respect 
to an amount rather than ATD) can be on any trading day (including 
prior to opening). The term intraday used elsewhere in Rule 6.12 
generally refers to when trading is open, while this temporary 
relief may be granted at any time on a trading day, including prior 
to the open of trading. Granting this relief at any of those times 
may be necessary to address market events or volatility, which may 
occur prior to an opening, in addition to when the Exchange is open 
for trading, and maintain a fair and orderly market during those 
times. The proposed rule change clarifies when this relief may be 
granted. The Exchange will continue to make and keep records of any 
determination to grant relief, and periodically review these 
determinations.
---------------------------------------------------------------------------

    The proposed rule change deletes the Exchange's flexibility to not 
apply this price parameter to immediate-or-cancel complex orders, as 
the Exchange believes these orders are also at risk of execution at 
extreme and potentially

[[Page 13683]]

erroneous prices and thus will benefit from applicability of these 
checks. The proposed rule change states this price parameter will not 
apply to complex orders routed from a PAR workstation or OMT. Orders 
routed from a PAR workstation or OMT are subject to manual handling, so 
the PAR or OMT operator will have evaluated the net price of a complex 
order based on then-existing market conditions prior to submitting the 
order for electronic execution, and thus there is minimal risk of 
execution at an erroneous price. The proposed rule change also states 
this price parameter will not apply to multi-class spreads, as these 
orders may execute in open outcry only, and thus the TPH will have the 
opportunity to evaluate the net price of the multi-class spread based 
on then-existing market conditions prior to representing the order on 
the trading floor, and thus there is minimal risk of execution at an 
erroneous price.

Example

    The System receives a complex order to buy Series A and sell Series 
B for a net debit price of $1.50. Suppose the NBBO for Series A is 
$2.00 to $2.20 and the NBBO for Series B is $1.00 to $1.20, making the 
national spread market for a strategy with a buy Series A leg and sell 
Series B leg $0.80 to $1.20. The Exchange has set the limit order price 
parameter at $0.20 (thus a limit order will be rejected if more than 
$0.20 above (below) the opposite side of the national spread market). 
Because the net debit price of the complex order is $0.30 above the 
offer of the national spread market, the System rejects this order.

Acceptable Percentage Range Parameter

    The proposed rule change amends Rule 6.53C, Interpretation and 
Policy .08(e), which currently provides the Exchange will not 
automatically execute an eligible complex order (and instead route the 
order via the order handling system pursuant to Rule 6.12) that is 
marketable if, following a complex order auction (``COA''), the 
execution would be at a price that is not within an acceptable 
percentage distance from the derived net price of the individual series 
legs that existed at the start of COA. The acceptable percentage 
distance is a percentage determined by the Exchange on a class-by-class 
basis and is no less than 3%.
    The proposed rule change amends this price protection mechanism to 
provide the Exchange will not automatically execute an incoming complex 
order (including a stock-option order) after the series for all legs of 
the complex order are open for trading \22\ that is marketable and 
would execute immediately upon submission to the complex order book 
(``COB'') or following a COA if the execution would be at a price 
outside an acceptable percentage range, which is the national spread 
market that existed when the System received the order or at the start 
of COA, as applicable, plus/minus:
---------------------------------------------------------------------------

    \22\ Rule 6.2B has separate price protections applicable to 
execution prices during pre-open and the opening rotation. The 
Exchange believes it is appropriate to apply the acceptable price 
range protection to orders when the leg series comprising the 
complex order are open to avoid interfering with the orderly opening 
process during which the System matches as many orders as possible.
---------------------------------------------------------------------------

     The amount equal to a percentage (which may not be less 
than 3%) of the national spread market (the ``percentage amount'') if 
that amount is not less than a minimum amount or greater than a maximum 
amount (the Exchange will determine the percentage and minimum and 
maximum amounts and announce them to Trading Permit Holders by 
Regulatory Circular);
     the minimum amount, if the percentage amount is less than 
the minimum amount; or
     the maximum amount, if the percentage amount is greater 
than the maximum amount.\23\
---------------------------------------------------------------------------

    \23\ The proposed rule change also amends the name of this price 
parameter to be consistent with the proposed changes.
---------------------------------------------------------------------------

    The System cancels an order (or any remaining size after partial 
execution of the order) that would execute or rest in the COB at a 
price outside the acceptable price range.
    This proposed rule change expands this parameter to incoming 
complex orders that do not COA and may immediately execute, as well as 
orders that do COA (to which the current parameter applies), which will 
potentially prevent erroneous executions of more complex orders. 
Additionally, under the proposed rule change, the System cancels the 
order (or remainder) that would execute or rest in the COB at a price 
outside the acceptable price range rather than routes it via the order 
handling system. Cancelling the order (or remainder) will prevent any 
future execution at a price ``too far away'' from the market and allow 
the Trading Permit Holder to reevaluate the order price based on 
current market prices and ensure it was not erroneous. The proposed 
rule change provides, while the acceptable price range will continue to 
be based on a percentage away from the market, the System will use the 
national spread market rather than the Exchange spread market for the 
reasons set forth above.\24\ The proposed rule change also puts in 
place a ``maximum'' price range (with the minimum and maximum amounts), 
which will keep the acceptable price range from being too wide and thus 
enhance the effectiveness of this price parameter to prevent erroneous 
executions.\25\
---------------------------------------------------------------------------

    \24\ Proposed subparagraph (e)(i) states the acceptable price 
range uses the Exchange spread market rather than the national 
spread market if the NBBO in any leg is locked, crossed or 
unavailable (and thus there is no reliable measure against which to 
compare the price of the order to determine its reasonability). 
Pursuant to proposed subparagraph (e)(i), the acceptable price range 
will also continue to use the Exchange spread market for pairs of 
orders submitted to AIM or SAM (as it does today), as the AIM and 
SAM functionality separately limits the prices at which those pairs 
may be submitted and executed. See Rules 6.74A(a) and Interpretation 
and Policy .07, and 6.74B(a) and Interpretation and Policy .01, 
respectively. If the System rejects either order in the pair 
pursuant to this parameter, then the System also cancels the paired 
order. Notwithstanding the foregoing, with respect to an AIM 
Retained (``A:AIR'') order as defined in Interpretation and Policy 
.09 to Rule 6.74A, if the System rejects the Agency Order pursuant 
to this check, then the System also rejects the contra-side order; 
however, if the System rejects the contra-side order pursuant to 
this check, the System still accepts the Agency Order if it 
satisfies the check. This currently is codified in paragraph (f) for 
stock-option orders and is being codified for all complex orders in 
proposed subparagraph (e)(iii), as it is consistent with current 
System functionality and the contingencies attached to those types 
of orders, as well as rules related to other price protections. See, 
e.g., Rule 6.53C, Interpretations and Policies .08(c) and (g). 
Additionally, the proposed rule change applies the provision in 
current paragraph (f), which states to the extent a contra-side 
order or response is marketable against the Agency Order, the 
execution price will be capped at the opposite side of the 
acceptable price range, to all complex orders in proposed paragraph 
(e)(iii).
    \25\ The maximum value acceptable price range in Rule 6.53C, 
Interpretation and Policy .08(g) similarly uses an acceptable price 
range determined by a percentage away from the maximum possible 
value of a spread, with a minimum and maximum amount.
---------------------------------------------------------------------------

    Rule 6.53C, Interpretation and Policy .08(f) sets forth a parameter 
currently applicable to stock-option orders, which is the same as the 
parameter in current paragraph (e), except the parameter in current 
paragraph (f) blocks executions of stock-option orders at prices more 
than a specified number of ticks away from the Exchange spread market, 
while current paragraph (e) blocks executions of complex orders at 
prices more than a specified percentage away from the Exchange spread 
market. Current paragraph (f) states the Exchange will not 
automatically execute a stock-option order that is marketable if, 
following a COA, the execution would not be within the acceptable 
derived net market for the strategy that existed at the start of COA. 
An ``acceptable derived net market'' for a strategy is calculated using 
the BBO in the individual option

[[Page 13684]]

series leg(s) and the NBBO in the stock leg plus/minus an acceptable 
tick distance, which is determined by the Exchange on a class-by-class 
and premium basis. The order would route via the order handling system 
pursuant to Rule 6.12.\26\ The proposed rule change deletes paragraph 
(f) and applies the parameter in paragraph (e) (as proposed to be 
amended) to stock-option orders. Proposed paragraph (e) will apply to 
stock-option orders in the same manner as it does to other complex 
orders.\27\ Therefore, the Exchange believes it simplifies its rules to 
include the enhanced parameter once in the rules using the proposed 
defined terms.
---------------------------------------------------------------------------

    \26\ Current paragraph (f) includes a provision regarding how 
the parameter applies to paired orders and auction responses. 
Proposed paragraph (e) will apply to incoming orders and will not 
apply to auction responses, but will apply to paired orders 
submitted to AIM and SAM (and A:AIR orders) as described in current 
paragraph (f) (including continued use of the Exchange spread market 
rather than the national spread market), and thus the proposed rule 
change moves this language to proposed paragraph (e)(iii), with 
nonsubstantive changes to make the language consistent with other 
rules. While this price protection will not cancel auction responses 
that would execute outside the acceptable price range, this price 
protection will prevent an order from executing outside the 
acceptable price range (including against an auction response), and 
thus responses will not execute against an order outside the 
acceptable price range.
    \27\ The proposed rule change makes a conforming change to the 
introductory paragraph of Interpretation and Policy .08.
---------------------------------------------------------------------------

Example

    Suppose the NBBO for Series A is $2.00 to $2.20 (50 x 50) and the 
NBBO for Series B is $1.00 to $1.20 (50 x 50), making the national 
spread market for a strategy with a buy Series A leg and sell Series B 
leg $0.80 to $1.20. Also suppose the BBO for Series A is $1.98 to $2.22 
(10 x 10) and the BBO for Series B is $0.98 to $1.22 (10 x 10), making 
the Exchange spread market for a strategy with a buy Series A leg and 
sell Series B leg $0.76 to $1.24. Pursuant to proposed Rule 6.12(a)(4), 
the Exchange has set the limit order price parameter at $0.20 (thus a 
limit order will be rejected if more than $0.20 above (below) the 
opposite side of the national spread market). The Exchange determined 
the following settings for the acceptable percentage range parameter: 
10%, with a minimum amount of $0.05 and a maximum amount of $0.10. 
Therefore, the acceptable percentage range is $0.72 to $1.30.\28\ The 
System receives a COA-eligible \29\ complex order to buy 35 Series A 
and sell 35 Series B for a net debit price of $1.40. A COA begins, and 
at the end of the COA, there are no auction responses or opposite side 
complex orders resting in the COB. The complex order executes against 
the 10 contracts in the leg market at a net price of $1.24 (buy 10 
contracts in Series A at the $2.22 offer, and sell 10 contracts in 
Series B at the $0.98 bid), which price is within the acceptable price 
range. The resulting BBO for Series A is $1.98 to $2.26 (10 x 10), and 
the resulting BBO for Series B is $0.94 to $1.22 (10 x 10), making the 
resulting Exchange spread market for a strategy with a buy Series A leg 
and sell Series B leg $0.76 to $1.32. The System cancels the remaining 
25 contracts of the order, because the next execution price with the 
leg markets of $1.32 and the $1.40 net debit price of the order are 
each outside the acceptable price range, and therefore, the order 
cannot trade or rest in the book at a price not outside the acceptable 
price range.
---------------------------------------------------------------------------

    \28\ The bid side of this range equals $0.72, which is $0.80 
minus 10% of $0.80 (or $0.08), an amount greater than the minimum 
and less than the maximum. The offer side of this range equals 
$1.30, which is $1.20 plus the maximum amount of $0.10, because 10% 
of $1.20 (or $0.12) is greater than that maximum amount.
    \29\ See Rule 6.53C(d) for a description of the COA process and 
order eligibility requirements. Note, in this example, the same 
result occurs for a non-COA eligible order--such order would execute 
against the 10 contracts resting in the leg markets at a net price 
of $1.24 upon submission to the COB rather than following a COA, and 
the System would cancel the remainder.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Act and the rules and regulations thereunder applicable to the 
Exchange and, in particular, the requirements of Section 6(b) of the 
Act.\30\ Specifically, the Exchange believes the proposed rule change 
is consistent with the Section 6(b)(5) \31\ requirements that the rules 
of an exchange be designed to prevent fraudulent and manipulative acts 
and practices, to promote just and equitable principles of trade, to 
foster cooperation and coordination with persons engaged in regulating, 
clearing, settling, processing information with respect to, and 
facilitating transactions in securities, to remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system, and, in general, to protect investors and the public interest. 
Additionally, the Exchange believes the proposed rule change is 
consistent with the Section 6(b)(5) \32\ requirement that the rules of 
an exchange not be designed to permit unfair discrimination between 
customers, issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \30\ 15 U.S.C. 78f(b).
    \31\ 15 U.S.C. 78f(b)(5).
    \32\ Id.
---------------------------------------------------------------------------

    In particular, the proposed rule change removes impediments to and 
perfects the mechanism of a free and open market and national market 
system because the limit order price parameter (intraday) and the 
acceptable percentage range parameter for complex orders will be based 
on the national spread market when available, which is based on the 
NBBO, and thus will more accurately reflect the entire market for a 
complex order at the time of execution than the Exchange spread market 
(which is based on the BBO). The Exchange believes the enhanced price 
protection mechanisms will further protect investors and the public 
interest and maintain fair and orderly markets by mitigating potential 
risks associated with market participants entering orders at extreme 
and potentially erroneous prices.
    With respect to the limit order price parameter for complex orders, 
the Exchange believes the national spread market when trading is open 
would be a better measure to use for purposes of determining the 
reasonability of the prices of orders and more accurately prevent 
executions of limit orders at erroneous prices, which ultimately 
protects investors. The Exchange also believes applying this check to 
immediate-or-cancel complex orders may prevent executions at extreme 
and potentially erroneous prices of these orders. The Exchange believes 
it is appropriate to have flexibility to determine to apply a different 
amount to complex orders entered during the pre-opening, a trading 
rotation, or a trading halt to reflect different market conditions 
during those times. Additionally, the Exchange believes it is 
appropriate to not apply this price check to complex orders routed from 
a PAR workstation or OMT, as those orders were subject to manual 
handling by a PAR or OMT operator who will have evaluated the net price 
of a complex order based on then-existing market conditions prior to 
submitted it for electronic execution, thus minimizing risk of an 
erroneous execution. Similarly, the Exchange believes it is appropriate 
to not apply this price check to multi-class spreads, as those will be 
handled by brokers who will have evaluated the net price of the spread 
based on then-existing market conditions prior to representation on the 
trading floor. This flexibility and non-applicability, as applicable, 
will further assist the Exchange with its efforts to maintain a fair 
and orderly market, which will ultimately protect investors.
    With respect to the acceptable percentage range parameter, the 
national

[[Page 13685]]

spread market would be a better measure to use for purposes of 
preventing executions of complex orders at erroneous prices, which 
ultimately protects investors. The proposed parameter will apply to 
complex orders that do not COA (and would execute against orders in the 
COB) in addition to those that do, which may prevent additional 
erroneous trades at prices that are extreme or ``too far away'' from 
the market.\33\ The Exchange believes the methodology to determine the 
acceptable price range is reasonable because using a percentage amount 
provides Trading Permit Holders with precise protection, while the pre-
set minimum and maximum ensures that the acceptable price range cannot 
be too wide or narrow to the point that the parameter would become 
ineffective.
---------------------------------------------------------------------------

    \33\ As further discussed below, the proposed rule change is 
substantially similar to NASDAQ OMX [sic] PHLX LLC (``PHLX'') Rule 
1098(i).
---------------------------------------------------------------------------

    The Exchange also believes the proposed rule change regarding how 
the acceptable percentage range parameter will apply to AIM and SAM 
orders is reasonable, as the proposed rule change is consistent with 
the contingencies attached to those types of orders.
    The proposed rule change to apply a single limit order price 
parameter and acceptable price range to all complex orders, including 
stock-option orders (subject to certain exceptions consistent with the 
current rules), will protect investors, as it simplifies the rules.

B. Self-Regulatory Organization's Statement on Burden on Competition

    CBOE does not believe that the proposed rule change will impose any 
burden on competition that is not necessary or appropriate in 
furtherance of the purposes of the Act. The proposed rule change will 
apply to all complex orders submitted to CBOE in the same manner. The 
enhancements to the price protection mechanisms applicable to all 
incoming orders will help further prevent potentially erroneous 
executions, which benefits all market participants. The proposed rule 
change will not impose any burden on intermarket competition, as it 
merely incorporates best prices available on other markets into current 
price protection mechanisms applicable to complex orders. Additionally, 
the proposed rule change is substantially similar to a rule of another 
options exchange.\34\
---------------------------------------------------------------------------

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange neither solicited nor received comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the foregoing proposed rule change does not: (i) 
Significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to Section 19(b)(3)(A) of the Act \35\ and Rule 19b-
4(f)(6) thereunder.\36\
---------------------------------------------------------------------------

    \35\ 15 U.S.C. 78s(b)(3)(A).
    \36\ 17 CFR 240.19b-4(f)(6). As required under Rule 19b-
4(f)(6)(iii), the Exchange provided the Commission with written 
notice of its intent to file the proposed rule change, along with a 
brief description and the text of the proposed rule change, at least 
five business days prior to the date of filing of the proposed rule 
change, or such shorter time as designated by the Commission.
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is: (i) 
Necessary or appropriate in the public interest; (ii) for the 
protection of investors; or (iii) otherwise in furtherance of the 
purposes of the Act. If the Commission takes such action, the 
Commission shall institute proceedings to determine whether the 
proposed rule change should be approved or disapproved.
