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

    The Exchange is proposing to amend its automatic execution and 
complex order processing rules to update existing price check parameter 
and order handling features and include some additional ones. The text 
of the proposed rule change is available on the Exchange's Web site 
(www.cboe.org/Legal), at the Exchange's Office of the Secretary and at 
the Commission.

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 those 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 parts 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 check parameter features 
that are designed to prevent incoming orders from automatically 
executing at potentially erroneous prices. These price check parameter 
features are designed to help maintain a fair and orderly market. The 
Exchange believes that the price check parameter features assist with 
the maintenance of fair and orderly markets by helping to mitigate the 
potential risks associated with orders drilling through multiple price 
points (thereby resulting in executions at prices that are extreme and 
potentially erroneous) and complex orders trading at prices that are 
inconsistent with particular complex order strategies (thereby 
resulting in executions at prices that are extreme and potentially 
erroneous). The Exchange is proposing to amend its automatic execution 
and complex order processing rules to update existing price check 
protection and order handling features to provide additional clarity on 
the operation of the functionality and to include some additional 
features.
    With respect to the CBOE Hybrid System Automatic Execution Feature, 
the Exchange is proposing to amend Rule 6.13 in various respects. By 
way of background, orders eligible for automatic execution through the 
CBOE Hybrid System may be automatically executed in accordance with 
Rule 6.13, Rule 6.13A, 6.14 or 6.14A, as applicable.\5\ Under the Rule 
6.13, the Exchange designates eligible order size, eligible order type, 
eligible order origin code (i.e., public customer orders, non-Market-
Maker broker-dealer orders, and Market-Maker broker-dealer orders), and 
classes in which the automatic execution feature shall be activated.\6\ 
In addition, other conditions may apply. For example, the Exchange may 
establish price check parameters that prevent orders from automatically 
executing outside acceptable price ranges or acceptable tick 
distances.\7\ Orders that are not eligible for automatic execution 
generally route on a class-by-class basis to PAR or, at the order entry 
firm's discretion, to the order entry firm's booth.
---------------------------------------------------------------------------

    \5\ SAL or the ``Simple Auction Liaison'' is a feature within 
the Hybrid System that auctions marketable orders for price 
improvement over the national best bid or offer (``NBBO'') as 
provided in Rule 6.13A. HAL or the ``Hybrid Agency Liaison'' is a 
feature within the Hybrid System that provides automated order 
handling in designated classes trading on the Hybrid System for 
qualifying orders that are not automatically executed. For example, 
eligible orders in classes that are multiply traded are not 
automatically executed on CBOE at prices that are inferior to the 
NBBO and instead may route to HAL. The original version of HAL is 
described in Rule 6.14. The second version of HAL, referred to as 
HAL2, is described in Rule 6.14A.
    \6\ See Rule 6.13(b)(i).
    \7\ See Rule 6.13(b)(v) and (vi).
---------------------------------------------------------------------------

    As for the proposed changes to Rule 6.13, first, the Exchange is 
proposing to delete unnecessary cross references within the rule in 
order to make the text consistent and easier to read.\8\ Second, 
currently the rule is silent on what happens when an order that would 
otherwise route to PAR is not eligible for PAR. Therefore, the Exchange 
is proposing to provide that, in instances where an order would route 
to PAR but the order is not eligible for PAR, then the remaining 
balance of the order will be cancelled. For example, assume an order 
entry firm has chosen to route its orders that are not eligible for 
automatic execution to PAR (and the order entry firm has also not 
specified that its orders can route to a booth if PAR is unavailable). 
With this configuration, if an order is routed by that firm to the

[[Page 4074]]

CBOE Hybrid System but the order is not eligible for automatic 
execution or book entry (e.g., because an incoming order is marketable 
and would execute at a price outside an acceptable price range), then: 
(i) The order would route to PAR so the order can be manually 
addressed, or (ii) if it is not eligible to route to PAR (e.g., because 
the particular order type is not eligible for PAR \9\ and the order 
entry firm has not specified that its orders can route to a booth if 
PAR is unavailable), then the remaining balance of the order will be 
cancelled.\10\ Third, currently the rule describes that the price check 
parameters are available in classes where HAL or HAL2 is activated and, 
depending on the particular version of HAL, differing price check 
features apply.\11\ Thus, the rule currently addresses two categories 
of options classes: HAL classes and HAL2 classes. For classes where HAL 
is activated, an acceptable BBO price range parameter may be applied. 
For classes where HAL2 is activated, an acceptable NBBO price range 
parameter and/or an acceptable tick distance parameter may be 
applied.\12\ The rule does not specify which features would be 
available in the instance where neither HAL nor HAL2 is activated. 
Therefore, the Exchange is proposing to provide that, for classes where 
neither HAL nor HAL2 is activated, the acceptable NBBO price range 
parameter and/or acceptable tick distance parameter may be applied 
(i.e., the same price check features applicable to HAL2 classes may 
apply to classes where neither HAL nor HAL2 is activated). The Exchange 
notes that HAL is not currently activated in any options classes and 
the related the price check parameter logic is therefore not currently 
being utilized. In addition, making it clear that the price check 
parameter features applicable to HAL2 classes to non-HAL/HAL2 classes 
is also consistent with how the Exchange's automated technology is 
currently configured and operating.
---------------------------------------------------------------------------

    \8\ In particular, various provisions within the rule text 
provide that certain orders will be routed to PAR or, at the order 
entry firm's discretion, to the order entry firm's booth. Some of 
those provisions contain the phrase ``pursuant to subparagraph 
(b)(i)(B) above,'' (see, e.g., existing Rule 6.13(b)(v)) while other 
provisions do not (see, e.g., existing Rule 6.13(b)(iii)). The 
Exchange believes this cross-reference is unnecessary. For 
consistency and easier reading, the Exchange is proposing to delete 
the cross-reference.
    \9\ For example, reserve orders (which are limit orders that 
have both a displayed size as well as an additional non-displayed 
size amount) and CBOE-Only orders (which are orders to buy or sell 
that are to be executed in whole or in part on the Exchange without 
routing to another market center and that are to be cancelled if 
routing would be required under CBOE Rules) are currently not 
eligible to route to PAR.
    \10\ The Exchange notes that other exchanges have features where 
orders that are not eligible for automatic execution are 
automatically cancelled or rejected. See, e.g., International 
Securities Exchange (``ISE'') Rule 714 (which provides in part that 
non-customer orders that are not automatically executed will be 
rejected automatically by the ISE's all electronic trading system). 
By comparison, because CBOE has a ``hybrid system'' that combines 
both electronic and open outcry trading, CBOE's process of routing 
orders that are not automatically executed by the Hybrid System to 
PAR or a booth provides for an additional, alternative means for an 
order to be manually addressed rather than simply be cancelled.
    \11\ HAL or the ``Hybrid Agency Liaison'' is a feature within 
the Hybrid System that provides automated order handling in 
designated classes trading on the Hybrid System for qualifying 
orders that are not automatically executed. The original version of 
HAL is described in Rule 6.14. The second version of HAL, referred 
to as HAL2, is described in Rule 6.14A.
    \12\ For classes on which HAL (Rule 6.14) is activated, the CBOE 
Hybrid System will not automatically execute eligible orders that 
are marketable if the width between the Exchange's best bid and best 
offer is not within an acceptable price range (as determined by the 
Exchange on a series-by-series basis for market orders and/or 
marketable limit orders and announced to the Trading Permit Holders 
via Regulatory Circular) (the ``acceptable BBO price range'' 
parameter). For classes on which HAL2 (Rule 6.14A) is activated, the 
CBOE Hybrid System will not automatically execute eligible orders 
that are marketable if (1) the width between the national best bid 
and national best offer is not within an acceptable price range (as 
determined by the Exchange on a series-by-series basis for market 
orders and/or marketable limit orders and announced to the Trading 
Permit Holders via Regulatory Circular) (the ``acceptable NBBO price 
range'' parameter), or (2) the execution would follow an initial 
partial execution on the Exchange and would be at a subsequent price 
that is not within an acceptable tick distance from the initial 
execution (as determined by the Exchange on a series by series and 
premium basis for market orders and/or marketable limit orders and 
announced to the Trading Permit Holders via Regulatory Circular) 
(the ``acceptable tick distance'' parameter). See Rules 6.13(b)(v)--
(vi).
---------------------------------------------------------------------------

    With respect to the complex order process, the Exchange is 
proposing to amend Rule 6.53C, Complex Orders on the Hybrid System, to 
update the price check parameters in various respects. First, currently 
the rule is silent on what happens when a complex order attempts to 
route to PAR but is not eligible for PAR. Therefore, similar to the 
changes noted above for Rule 6.13, the Exchange is proposing to amend 
Rule 6.53C.08 to provide that, in instances where a complex order would 
normally route to PAR if a complex order price check parameter is 
triggered but the order is not eligible to route to PAR, then the 
remaining balance of the complex order will be cancelled.
    Second, the Exchange is proposing to replace specific references in 
Rule 6.53C.08 to routing orders to BART (the booth automated routing 
terminal) and an order entry firm's booth printer with a general 
reference to an order entry firm's booth. The Exchange no longer 
utilizes the particular system that it had referred to as BART and 
believes that the general reference to routing an order to an order 
entry firm's booth is more accurate for its rules.
    Third, the Exchange is proposing to include descriptive headings in 
the rule text for each of the existing price check parameters. The 
Exchange is also proposing to break the description of the existing 
same expiration strategy price check parameters into two separate 
paragraphs instead of a single paragraph. We believe these changes will 
make it easier for users to read and understand the operation of these 
price protection features. These changes are simply non-substantive 
formatting changes and do not impact the operation of the various 
features.
    Fourth, the market width parameter under Rule 6.53C.08(a) currently 
provides that the complex order book (``COB'') will not automatically 
execute eligible complex orders that are market orders if the width 
between the Exchange's best bid and best offer are not within an 
acceptable price range. The rule text provides that the acceptable 
price range is no less than 1.5 times the corresponding bid/ask 
differential requirements determined by the Exchange on a class-by-
class basis pursuant to Rule 8.7(b)(iv). In addition, the rule text 
currently provides that such market complex orders route on a class-by-
class basis to PAR, BART or, at the order entry firm's discretion, to 
the order entry firm's booth.
    The Exchange is proposing to revise this provision in various 
respects. As discussed above, the Exchange is proposing to make it 
clear that the remaining balance of a complex order will be cancelled 
if it would normally route to PAR but is not eligible and to delete 
references to BART. In addition, the Exchange is proposing to provide 
that the Exchange may determine to apply these price check parameters 
to market orders and/or marketable limit orders. However, whereas 
market orders that are subject to this price protection feature route 
to PAR, a booth or are cancelled, marketable limit orders would be held 
in the Hybrid System. Any such orders held in the Hybrid System would 
not be eligible to automatically execute until after the market width 
parameter condition is resolved. In addition, while being held in the 
Hybrid System, such orders would be displayed in the COB as applicable. 
This functionality for marketable limit orders is currently in use but 
not expressly covered in the rules. The Exchange believes that 
extending the same price check logic to not automatically execute such 
marketable limit orders but to continue to hold such orders in the 
Hybrid System is reasonable and appropriate because, as with market 
orders, this feature should help to prevent executions of such limit 
orders at extreme and potentially erroneous prices. In contrast to 
market orders, marketable limit orders are able to be

[[Page 4075]]

held in the Hybrid System because they have a price associated with 
them. The Exchange also notes that applying market width price check 
logic to market orders and/or marketable limit orders is consistent 
with other existing price check parameters that apply to both market 
orders and marketable limit complex orders.\13\ In addition, rather 
than cross reference corresponding bid/ask differential requirements, 
the Exchange is proposing to specify the minimum acceptable price range 
within Rule 6.53C.08(a). Specifically, the acceptable price range will 
be no less than: $0.375 between the bid and offer for each option 
contract for which the bid is less than $2, $0.60 where the bid is at 
least $2 but does not exceed $5, $0.75 where the bid is more than $5 
but does not exceed $10, $1.20 where the bid is more than $10 but does 
not exceed $20, and $1.50 where the bid is more than $20.\14\
---------------------------------------------------------------------------

    \13\ See, e.g., Rule 6.13(vi) (which provides, among other 
things, that the Exchange will not automatically execute eligible 
orders that are marketable if the width between the NBBO is not 
within an acceptable price range (as determined by the Exchange on a 
series by series basis for market orders and/or marketable limit 
orders and announced to Trading Permit Holders via Regulatory 
Circular).
    \14\ These amounts are equal to 1.5 times the bid/ask 
differential requirements that the Exchange had in its rules at the 
time the price check parameters were adopted and are the same as the 
acceptable price range parameters set forth in Rule 6.13(b)(v)-(vi).
---------------------------------------------------------------------------

    Fifth, the debit-to-credit (credit-to-debit) parameters under Rule 
6.53C.08(b) currently provide that (i) a market order that would be 
executed at a net credit price after receiving a partial execution at a 
net debit price would not be automatically executed (the ``debit-to-
credit'' parameter), and (ii) a market order that would be executed at 
a net debit price after receiving a partial execution at a net credit 
price would not be automatically executed (the ``credit-to-debit'' 
parameter). The Exchange is proposing to eliminate the debit-to-credit 
parameter because it is not possible for such a scenario to occur and 
therefore the parameter is unnecessary. (Because orders are executed at 
the best available price and then the next best price, a market order 
would never execute at a net debit price then at a net credit price.)
    Sixth, the Exchange is proposing to change the existing same 
expiration strategy price check parameters to distinguish between its 
application to limit orders and to market orders. The Exchange is also 
proposing to eliminate a provision that would make this price check 
parameter feature available to ratio orders should the Exchange 
determine to do so. As the term implies, the ``same expiration 
strategy'' price protection parameters apply to certain complex order 
strategies where all the option series have the same expiration.\15\ 
The functionality is designed to detect scenarios where (i) a limit 
order is entered at a net credit price when it clearly should have been 
entered at a net debit price (or vice versa) and (ii) a market order 
would be executed at a net debit price when it clearly should be 
executed at a net credit price (but not vice versa).\16\
---------------------------------------------------------------------------

    \15\ See Rule 6.53C.08(c).
    \16\ A same expiration strategy market order that would result 
in an execution at a net credit price (i.e., the net sale proceeds 
from the series being sold are more than the net purchase cost from 
the series being bought) but that would normally execute at a net 
debit price (i.e., the net sale proceeds from the series being sold 
are less than the net purchase cost from the series being bought) 
would be a favorable execution for the market order and would not 
trigger this price check parameter.
---------------------------------------------------------------------------

    Currently the rule text provides that, if the conditions for this 
price check parameter exist when a complex order is routed to COB, then 
the order will be rejected. The rule text also currently provides that, 
to the extent the parameters are triggered once an order is resting in 
COB or after an incoming order receives a partial execution, such a 
complex order will route on a class-by-class basis to PAR, BART, or at 
the order entry firm's discretion to the order entry firm's booth 
printer. The provision does not distinguish between limit orders and 
market orders. The Exchange is proposing to amend the text to 
separately describe how the two categories of orders are processed.
    With respect to limit orders, the proposed changes to the text 
provide that incoming limit orders will be rejected under this 
parameter only if the conditions exist when the order is first routed 
to COB. The provisions about resting orders and partial executions are 
not applicable to limit orders because incoming limit orders that are 
priced at a net price that meets the conditions are rejected outright 
upon routing to COB and never get to the point where they are resting 
or partially executed. With respect to market orders, proposed changes 
to the text provide that, to the extent the parameters are triggered 
when an incoming market order is routed to COB or after an incoming 
market order is subject to COA, any part of the market order that may 
be executed within an acceptable price range will be executed 
automatically and the part of the order that would execute at a net 
debit price will route on a class-by-class basis to PAR or, at the 
order entry firm's discretion, to the order entry firm's booth. If an 
order is not eligible to route to PAR, then the remaining balance will 
be cancelled. (A market order would never rest in COB, so that 
provision will be removed from the rule text.) \17\ The following 
examples illustrate this price check parameter:
---------------------------------------------------------------------------

    \17\ As discussed above, the Exchange is also proposing to 
delete the references to BART and booth printers.
---------------------------------------------------------------------------

    Example 1: Assume a complex order to buy 50 Jan 45 XYZ calls and 
sell 50 Jan 50 XYZ calls is entered with a limit that is a net credit 
price (i.e., the net sale proceeds from the Jan 50 calls are larger 
than the net purchase cost from the Jan 45 calls). Such an order would 
appear to be erroneously priced as a net credit--it should instead be a 
net debit--because normally a person would expect that the Jan 50 calls 
would not cost more than the Jan 45 calls. As a result, upon routing to 
COB, such a limit order would be rejected.
    Example 2: Assume a butterfly spread to buy 50 Jan 45 XYZ calls, 
sell 100 Jan 50 XYZ calls and buy 50 Jan 55 XYZ calls is entered at a 
net credit price (i.e., the net sale proceeds from the Jan 50 calls are 
more than the net purchase cost from the Jan 45 and 55 calls). Such an 
order would appear to be erroneously priced as a net credit--it should 
instead be a net debit--because normally a person would expect that 
selling the middle 50 strike would result in less than the cost of 
buying the upper 55 and lower 45 strikes. As a result, upon routing to 
COB, such a limit order would be rejected.
    Example 3: Assume a market order to buy 50 Jan 45 XYZ calls and 
sell 50 Jan 40 XYZ calls is entered. Also assume that the Jan 45 XYZ 
calls are quoted $4.00-$4.10 for 10 contracts and the next available 
offer is $4.30 for 100 contracts, and that the Jan 40 XYZ calls are 
quoted $4.50-$4.60 for 10 contracts and the next available bid is $4.20 
for 100 contracts. Under this scenario, the incoming market order would 
receive an execution for 10 spreads at a net credit price of $0.40 each 
(i.e., the net sale proceeds from the Jan 40 Series are larger than the 
net purchase cost from the Jan 45 Series). When the series decrement, 
the net execution price would become a net debit price of $0.10 each 
(i.e., the net sale proceeds from the Jan 40 Series are less than the 
net purchase cost from the Jan 45 Series). Such an execution would 
appear to be erroneous because normally a person in this scenario would 
expect to execute the vertical spread at a net credit price. As a 
result, upon routing to COB, 10 contracts would execute at a net credit 
price of $0.40 each and the remaining 40 contracts would route on a 
class-by-

[[Page 4076]]

class basis to PAR, or at the order entry firm's discretion, to the 
order entry firm's booth. If the market order is not eligible to route 
to PAR, then the remaining balance would be cancelled.
    Example 4: Assume a market order to buy 50 Jan 45 XYZ calls and 
sell 50 Jan 40 XYZ calls is routed to COA. Also assume that at the end 
of the COA the Jan 45 XYZ calls are quoted $4.00-$4.10 for 10 contracts 
and the next available offer is $4.30 for 100 contracts, and that the 
Jan 40 XYZ calls are quoted $4.50-$4.60 for 10 contracts and the next 
available bid is $4.20 for 100 contracts. To the extent the market 
order can execute at prices within the price check parameter, then that 
part of the order would execute (i.e., 10 vertical spreads will execute 
at a net credit price of $0.40 each). To the extent that the price 
check parameters are triggered at the conclusion of COA, then that part 
of the market order would route on a class-by-class basis to PAR, or at 
the order entry firm's discretion, to the order entry firm's booth 
(i.e., 40 vertical spreads will route). If the market order is not 
eligible to route to PAR, then the remaining balance would be 
cancelled.
    As noted above, the Exchange is also proposing to delete a 
provision in the rule that provides that the Exchange may determine to 
make the same expiration strategy price check parameters available to 
applicable ratio orders (as such applicable ratios are determined by 
the Exchange on a class-by-class basis). The Exchange has not activated 
this feature for ratio orders and has no intention to do so at this 
time. Therefore, the Exchange is proposing to delete this provision 
from the rule at this time.\18\
---------------------------------------------------------------------------

    \18\ In the future, should the Exchange would determine to apply 
this price check parameter feature to ratio orders, the Exchange 
would address it through a separate rule change filing.
---------------------------------------------------------------------------

    Finally, seventh, the Exchange is proposing to codify a price check 
parameter for orders processed via COA, which is currently in use but 
not expressly covered in the rules. Under this parameter the Exchange 
may determine on a class-by-class basis (and announce to Trading Permit 
Holders via Regulatory Circular pursuant to Rule 6.53C.01) that COA 
will not automatically execute a COA-eligible order that is marketable 
if 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. For purposes of this provision, 
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. The Exchange believes a 3 percent level is reasonable and 
appropriate because a marketable order that would deviate from the 
derived net market by that percentage or more may be indicative of an 
extreme or potentially erroneous price, and a broker would generally 
want to evaluate the order further before receiving an automatic 
execution. The Exchange also believes that a 3 percent minimum is 
reasonable and appropriate in comparison to other price check 
parameters it currently has available.\19\ To the extent the parameters 
under this provision are triggered, such a complex order would route on 
a class-by-class basis to PAR, or, at the order entry firm's 
discretion, to the order entry firm's booth. Again, as discussed above, 
if an order is not eligible to route to PAR, then the remaining balance 
will be cancelled.
---------------------------------------------------------------------------

    \19\ The ``acceptable percentage distance'' price check 
parameter for complex orders is adapted from the ``acceptable tick 
distance'' parameter set forth in Rule 6.13(b)(vi), which provides 
that the acceptable tick distance shall not be less than 2 minimum 
increment ticks.
---------------------------------------------------------------------------

    For example, the Exchange could determine that the acceptable 
percentage distance is 5%. Assume at the start of COA the individual 
leg market in Series A is $1.00-$1.20 and in series B is $2.00-$2.20 
and the derived leg market is $0.80 (net debit)-$1.20 (net credit). The 
acceptable percentage distance would be $0.04 (5% x $0.80) for orders 
to buy Series A and sell series B and $0.06 (5% x $1.20) for orders to 
sell Series A and buy series B. As a result, COA would execute a COA-
eligible order at prices ranging from $0.84 (net debit)-$1.26 (net 
credit), but not an order priced at a net debit of $0.85 or more or a 
net credit of $1.27 or more.
2. Statutory Basis
    The proposed rule change is consistent with Section 6(b) of the Act 
\20\ in general and furthers the objectives of Section 6(b)(5) of the 
Act \21\ in particular in that it should promote just and equitable 
principles of trade, serve to remove impediments to and perfect the 
mechanism of a free and open market and a national market system, and 
protect investors and the public interest. The Exchange believes that 
the complex order price check parameters described in Rule 6.53C assist 
in the automatic execution and processing of orders that are subject to 
the Exchange's complex order processing. The Exchange also believes 
these price check parameters assist with the maintenance of fair and 
orderly markets by helping to mitigate the potential risks associated 
with orders drilling through multiple price points (thereby resulting 
in executions at prices that are extreme and potentially erroneous) and 
complex orders trading at prices that are inconsistent with particular 
complex order strategies (thereby resulting in executions at prices 
that are extreme and potentially erroneous). In this regard, for 
example, the Exchange notes that the acceptable percentage distance 
parameter is designed to mitigate the potential risks of executions at 
prices that are not within an acceptable percentage distance from the 
derived net market price of the individual series legs. The Exchange 
also notes that the extension of the BBO market width logic to include 
marketable limit orders is designed to help prevent executions of such 
limit orders at extreme and potentially erroneous prices in a manner 
consistent with the existing logic utilized for market orders. The 
Exchange also believes that the proposed changes to the rule text will 
make it easier for users to read and understand the operation of the 
complex order price check parameters, and will better and more fully 
describe the operation of the parameters. In addition, the Exchange 
believes the proposed revisions to Rule 6.13 will better and more fully 
describe the operation of the Hybrid System automatic execution 
feature, in particular the processing of orders that are not eligible 
for routing to PAR and the price check parameter protections that are 
applicable for non-HAL/HAL2 classes.

necessary or appropriate in the public interest, for the protection of 
investors, or otherwise in furtherance of the purposes of the Act.
