Self-Regulatory Organizations; Nasdaq 

ISE, LLC; Notice of Filing and 

Immediate Effectiveness of Proposed 

Rule Change To Codify the Definitions 

of the Protocols That Members Can 

Use To Enter Quotes and Orders 

July 27, 2018. 

Pursuant to Section 19(b)(1) of the 

Securities Exchange Act of 1934 

(‘‘Act’’),1 and Rule 19b–4 thereunder,2

notice is hereby given that on July 16, 

2018, Nasdaq ISE, LLC (‘‘ISE’’ or 

‘‘Exchange’’) filed with the Securities 

and Exchange Commission 

(‘‘Commission’’) the proposed rule 

change as described in Items I, II, and 

III, below, which Items have been 

prepared by the Exchange. The 

Commission is publishing this notice to 

solicit comments on the proposed rule 

change from interested persons. 

I. Self-Regulatory Organization’s 

Statement of the Terms of Substance of 

the Proposed Rule Change 

The Exchange proposes to codify the 

definitions of the protocols that 

Members can use to enter quotes and 

orders on the Exchange. 

The text of the proposed rule change 

is available on the Exchange’s website at 

http://ise.cchwallstreet.com/, at the 

principal office of the Exchange, 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 purpose of the proposed rule 

change is to codify the definitions of the 

protocols that Members use to enter 

quotes and orders on the Exchange, 

specifically, the Specialized Quote Feed 

(‘‘SQF’’), Ouch to Trade Options 

(‘‘OTTO’’), Financial Information 

eXchange (‘‘FIX’’), and Nasdaq Precise 

(‘‘Precise’’). On June 23, 2017, the 

Exchange filed a proposed rule change 

that established the ports that Members 

use to connect to the Exchange, 

including ports used for quote and order 

entry—i.e., SQF, OTTO and FIX.3 The 

Exchange has also filed several 

proposed fee and other rule changes that 

briefly describe the availability of 

Precise, which is the Exchange’s 

proprietary front-end interface used by 

Electronic Access Members (‘‘EAMs’’) 

and their Sponsored Customers 4 to send 


daltland on DSKBBV9HB2PROD with NOTICES
Federal Register / Vol. 83, No. 149 / Thursday, August 2, 2018 / Notices 37871 

Supplementary Material to Rule 706. Market makers 

must connect to the Exchange via SQF, which is the 

Exchange’s quoting protocol, and are therefore not 

eligible to use Precise. 

5See Securities Exchange Act Release No. 53788 

(May 11, 2006), 71 FR 28728 (May 17, 2006) (SR– 

ISE–2006–19) (proposed fee change establishing 

Precise). SR–ISE–2006–19 described Precise as 

ISE’s proprietary front-end interface used by EAMs 

to send orders to ISE and view market data. See also 

Securities Exchange Act Release No. 81034 (June 

27, 2017), 82 FR 30923 (July 3, 2017) (SR–ISE– 

2017–58) (proposed rule change regarding how 

Immediate-or-Cancel Orders will be handled); and 

Securities Exchange Act Release No. 81971 (October 

27, 2017), 82 FR 50907 (November 2, 2017) (SR– 

ISE–2017–94) (proposed rule change related to the 

Kill Switch risk protection). 

6The Exchange’s affiliates—i.e., Nasdaq GEMX, 

LLC (‘‘GEMX’’), Nasdaq MRX, LLC (‘‘MRX’’), 

Nasdaq PHLX LLC (‘‘Phlx’’), Nasdaq Options 

Market (‘‘NOM’’), and Nasdaq BX, LLC (‘‘BX’’)— 

intend to file similar rule changes as part of this 

exercise. 

7All of the notification messages available on 

SQF ports as described above (i.e., options symbol 

directory messages, system event messages, trading 

action messages, etc.) are configurable in that 

market makers can select the specific types of 

notifications they wish to receive on their SQF 

ports. As such, SQF Purge Interface ports are a 

subpart of SQF ports that have been configured to 

only receive and notify of purge requests. 

orders to the Exchange and perform 

other related functions.5 The protocols 

used by Members to submit quotes and 

orders play an important role in the 

operation of the trading system as 

critical Exchange functionality used by 

Members to transact in options and 

stock tied to options is offered through 

these protocols. The Exchange therefore 

believes that codifying definitions of 

these protocols in its rules will increase 

transparency around its operations. 

As it relates to FIX, OTTO, and SQF, 

the proposed language is substantially 

similar to the language included in SR– 

ISE–2017–62 with changes to more 

clearly and accurately reflect the certain 

information included on each protocol, 

such as by separating out different 

categories of messages (e.g., auction 

orders, auction notifications, and 

auction responses). Furthermore, the 

proposed definitions will be 

harmonized where appropriate with 

definitions to be included in the rules 

of the Exchange’s affiliated options 

markets, including by using consistent 

terms to define the buckets of 

information transmitted, or the features 

available, on each protocol.6 Although 

the Exchange is changing how it 

categorizes various features included on 

FIX, OTTO, and SQF as part of its 

harmonization effort, the list of features 

included in the proposed definitions are 

intended to be exhaustive with respect 

to the buckets of information provided 

on each protocol. The Exchange also 

seeks to memorialize Precise to reflect 

the specific categories of features that 

are available on the Precise front-end 

today (e.g., order and execution 

management, market data, and risk 

management). Overall, the Exchange 

believes that the proposed changes will 

allow Members to more easily 

understand what information is 

available on which protocol. 

As proposed, Supplementary Material 

.03 to Rule 715 (i.e., Types of Orders) 

will provide that the Exchange offers 

Members the following protocols for 

entering orders and quotes respectively: 

A. Financial Information eXchange 

Ports 

When the Exchange initially filed to 

adopt order and quote entry protocols, 

it described the FIX protocol as follows: 

‘‘FIX is an interface that allows market 

participants to connect and send orders 

and auction orders into the Exchange. 

Data includes the following: (1) Options 

Symbol Directory Messages; (2) System 

Event Messages (e.g., start of messages, 

start of system hours, start of quoting, 

start of opening); (3) Option Trading 

Action Messages (e.g., halts, resumes); 

(4) Execution Messages; (5) Order 

Messages (order messages, risk 

protection triggers or purge 

notifications).’’ 

The Exchange now proposes to codify 

the following definition of FIX in its 

rulebook: ‘‘Financial Information 

eXchange’’ or ‘‘FIX’’ is an interface that 

allows Members and their Sponsored 

Customers to connect, send, and receive 

messages related to orders and auction 

orders to the Exchange. Features include 

the following: (1) Execution messages; 

(2) order messages; (3) risk protection 

triggers and cancel notifications; and (4) 

post trade allocation messages. 

B. Ouch To Trade Options Ports 

When the Exchange initially filed to 

adopt order and quote entry protocols, 

it described the OTTO protocol as 

follows: ‘‘OTTO is an interface that 

allows market participants to connect 

and send orders, auction orders and 

auction responses into the Exchange. 

Data includes the following: (1) Options 

Auction Notifications (e.g., Flash, PIM, 

Solicitation and Facilitation or other 

information); (2) Options Symbol 

Directory Messages; (3) System Event 

Messages (e.g., start of messages, start of 

system hours, start of quoting, start of 

opening); (5) Option Trading Action 

Messages (e.g., halts, resumes); (6) 

Execution Messages; (7) Order Messages 

(order messages, risk protection triggers 

or purge notifications).’’ 

The Exchange now proposes to codify 

the following definition of OTTO in its 

rulebook: ‘‘Ouch to Trade Options’’ or 

‘‘OTTO’’ is an interface that allows 

Members and their Sponsored 

Customers to connect, send, and receive 

messages related to orders, auction 

orders, and auction responses to the 

Exchange. Features include the 

following: (1) options symbol directory 

messages (e.g., underlying and complex 

instruments); (2) system event messages 

(e.g., start of trading hours messages and 

start of opening); (3) trading action 

messages (e.g., halts and resumes); (4) 

execution messages; (5) order messages; 

(6) risk protection triggers and cancel 

notifications; (7) auction notifications; 

(8) auction responses; and (9) post trade 

allocation messages. 

C. Specialized Quote Feed Ports 

When the Exchange initially filed to 

adopt order and quote entry protocols, 

it described the SQF protocol as follows: 

‘‘SQF is an interface that allows market 

makers to connect and send quotes, 

sweeps and auction responses into the 

Exchange. Data includes the following: 

(1) Options Auction Notifications (e.g., 

opening imbalance, Flash, PIM, 

Solicitation and Facilitation or other 

information); (2) Options Symbol 

Directory Messages; (3) System Event 

Messages (e.g., start of messages, start of 

system hours, start of quoting, start of 

opening); (4) Option Trading Action 

Messages (e.g., halts, resumes); (5) 

Execution Messages; (6) Quote Messages 

(quote/sweep messages, risk protection 

triggers or purge notifications).’’ 

The Exchange now proposes to codify 

the following definition of SQF in its 

rulebook: ‘‘Specialized Quote Feed’’ or 

‘‘SQF’’ is an interface that allows market 

makers to connect, send, and receive 

messages related to quotes, Immediateor-Cancel Orders, and auction responses 

to the Exchange. Features include the 

following: (1) Options symbol directory 

messages (e.g., underlying and complex 

instruments); (2) system event messages 

(e.g., start of trading hours messages and 

start of opening); (3) trading action 

messages (e.g., halts and resumes); (4) 

execution messages; (5) quote messages; 

(6) Immediate-or-Cancel Order 

messages; (7) risk protection triggers and 

purge notifications; (8) opening 

imbalance messages; (9) auction 

notifications; and (10) auction 

responses. The SQF Purge Interface only 

receives and notifies of purge requests 

from the market maker.7

D. Nasdaq Precise 

‘‘Nasdaq Precise’’ or ‘‘Precise’’ is a 

front-end interface that allows 

Electronic Access Members and their 

Sponsored Customers to send orders to 

the Exchange and perform other related 


daltland on DSKBBV9HB2PROD with NOTICES
37872 Federal Register / Vol. 83, No. 149 / Thursday, August 2, 2018 / Notices 

8For example, Cboe Exchange, Inc. currently 

offers a similar front-end order and execution 

management system called PULSeSM that allows 

users to send orders to Cboe Options Exchange, C2 

Options, Cboe Futures Exchange, and other U.S. 

options and stock exchanges. See https://

www.cboe.org/hybrid/pulsesalessheet.pdf. 

9The Exchange is characterizing the risk 

protections on Precise under a broader category of 

risk management compared to the risk protection 

categories on the other protocols because Precise 

also supports administrator capability for accessing 

and setting risk parameters for multiple users 

within a member firm. 

10See Rule 711(d). Precise is able to send a 

message to the Exchange to initiate the kill switch 

through Precise. 

11 Done away trade reports allow Precise users to 

record orders and executions, including executions 

on a different venue than the Exchange.

functions. Features include the 

following: (1) order and execution 

management: enter, modify, and cancel 

orders on the Exchange, and manage 

executions (e.g., parent/child orders, 

inactive orders, and post-trade 

allocations); (2) market data: access to 

real-time market data (e.g., NBBO and 

Exchange BBO); (3) risk management: 

set customizable risk parameters (e.g., 

kill switch); and (4) book keeping and 

reporting: comprehensive audit trail of 

orders and trades (e.g., order history and 

done away trade reports). 

Precise is a software application that 

is offered by the Exchange to EAMs and 

their Sponsored Customers. Use of 

Precise is completely voluntary. The 

Exchange makes Precise available to 

EAMs and their Sponsored Customers 

as a convenience for entering and 

managing orders, but the protocol is not 

an exclusive means for any user to send 

orders to ISE. Precise is merely a frontend interface to the Exchange’s existing 

trading system, and is designed as an 

alternative to the Exchange’s other 

protocols (i.e., FIX, OTTO, and SQF) for 

the sending of orders to ISE. Precise is 

also an alternative to similar front-end 

order and execution management 

systems currently offered by other 

technology providers as well as other 

exchanges.8

Precise provides users with access to 

ISE’s regular and complex order books. 

The protocol offers order and execution 

features that allow users to send, 

modify, and cancel their orders, and 

manage executions. For example, the 

protocol offers users the capability to 

stage larger orders and divide them into 

smaller orders for execution (i.e., 

parent/child orders), or stage multiple 

orders to send for execution at a later 

time (i.e., inactive orders). Precise also 

offers post trade allocation, including 

the capability for users to directly adjust 

clearing information on the front-end 

protocol. Precise users can also access 

and display real-time market data such 

as the National Best Bid and Offer 

(‘‘NBBO’’) and the Exchange Best Bid 

and Offer (‘‘Exchange BBO’’). 

Precise also provides risk 

management capabilities that allow 

users to set customizable risk 

parameters.9 For example, Precise 

supports the kill switch risk protection 

feature, which is an optional tool that 

enables members to initiate a message(s) 

to the Exchange’s trading system to 

promptly cancel orders and restrict 

entry of new orders until re-entry has 

been enabled.10 Lastly, Precise provides 

a comprehensive audit trail of orders 

and trades through its book keeping and 

reporting features, including order 

history reports and done away trade 

reports.11

2. Statutory Basis 

The Exchange believes that the 

proposed rule change is consistent with 

Section 6(b) of the Securities Exchange 

Act of 1934 (the ‘‘Act’’),12 in general, 

and furthers the objectives of Section 

6(b)(5) of the Act,13 in particular, in that 

it is designed to promote just and 

equitable principles of trade, to remove 

impediments to and perfect the 

mechanism for a free and open market 

and a national market system, and, in 

general, to protect investors and the 

public interest. 

The Exchange believes that the 

proposed rule change is consistent with 

the protection of investors and the 

public interest as it codifies the 

protocols used to connect to the 

Exchange’s trading system. As discussed 

above, the Exchange previously filed to 

establish FIX, OTTO, and SQF in SR– 

ISE–2017–62. These protocols will now 

be codified in the Exchange’s rulebook. 

In addition, the Exchange has briefly 

described Precise in various proposed 

rule changes filed with the Commission. 

In the interest of transparency, the 

Exchange has included a more fulsome 

description of the functionalities offered 

via Precise in this proposed rule change, 

and is codifying language in its rules 

that would describe this protocol. 

While no functional changes to the 

protocols are proposed in this filing, the 

Exchange believes that including a 

description of the protocols in its 

rulebook will benefit Members by 

increasing transparency around the 

operation of the Exchange. Furthermore, 

the proposed definitions being included 

in the rulebook will more clearly and 

accurately reflect the information 

included on the protocols, and will be 

harmonized with language to be 

included in the rules of its affiliated 

exchanges to the extent that the 

protocols operate in the same manner. 

The protocols described in this filing 

provide a range of important features to 

Members, including the ability to 

submit quotes and orders, and perform 

other functions necessary to manage 

trading on the Exchange. The Exchange 

believes codifying the quote and order 

entry protocols will increase 

transparency to the Members that use 

these protocols to connect to the 

Exchange. 

B. Self-Regulatory Organization’s 

Statement on Burden on Competition 

In accordance with Section 6(b)(8) of 

the Act,14 the Exchange does not believe 

that the proposed rule change will 

impose any burden on intermarket or 

intramarket competition that is not 

necessary or appropriate in furtherance 

of the purposes of the Act. As explained 

above, the Exchange is codifying the 

quote and order entry protocols that 

Members use to connect to the 

Exchange’s trading system. The 

Exchange does not believe that 

codifying these protocols in the 

rulebook will have any competitive 

impact. FIX, OTTO, and SQF were 

established in SR–ISE–2017–62, and are 

already available to Members, who use 

these protocols to connect and manage 

their trading activity on the Exchange. 

Adding rule language that describes 

these Exchange offerings will increase 

transparency around the operation of 

the Exchange without having any 

impact on intermarket or intramarket 

competition. Furthermore, Precise is a 

voluntary piece of functionality that 

EAMs and their Sponsored Customers 

may use as a convenience for entering 

and managing orders and executions, as 

an alternative to the Exchange’s other 

protocols (i.e., FIX, OTTO, and SQF). 

Precise is also an alternative to similar 

front-end order and execution 

management systems currently offered 

by other technology providers as well as 

other exchanges (e.g., PULSe). If market 

participants believe that other products 

available in the marketplace are more 

beneficial than Precise, they will simply 

use those products instead. For the 

foregoing reasons, the Exchange does 

not believe that its proposal to codify 

Precise will impose any burden on 

intermarket or intramarket competition 

that is not necessary or appropriate in 

furtherance of the purposes of the Act.

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

A. Self-Regulatory Organization’s 

Statement of the Purpose of, and 

Statutory Basis for, the Proposed Rule 

Change 

1. Purpose 

The purpose of the proposed rule 

change is to codify the definitions of the 

protocols that Members use to enter 

quotes and orders on the Exchange, 

specifically, the Specialized Quote Feed 

(‘‘SQF’’), Ouch to Trade Options 

(‘‘OTTO’’), and Financial Information 

eXchange (‘‘FIX’’). On July 20, 2017, the 

Exchange filed a proposed rule change 

that established the ports that Members 

use to connect to the Exchange, 

including ports used for quote and order 

entry—i.e., SQF, OTTO and FIX.3 The 

protocols used by Members to submit 

quotes and orders play an important 

role in the operation of the trading 

system as critical Exchange 

functionality used by Members to 

transact in options is offered through
