Hello,

The SEC is requesting industry input into the proposed Consolidated Audit Trail 
System. The Consolidated Audit Trail System is intended to enable regulators to 
track information related to trading orders received and executed across the 
securities markets.

Details of the Consolidated Audit Trail System including how to make an online 
submission are at: http://www.sec.gov/news/press/2010/2010-86.htm

I wanted to encourage member firms and individuals of the FIX community to make 
a submission. I have copied my personal submission below in case anyone is 
interested. My submission recommends that FIX is used as the data format for 
the Consolidated Audit Trail System.

Thanks

Martin Koopman

Re: Recommendation to Use FIX Protocol in Consolidated Audit Trail System

Dear Sir or Madam:

I work as a consultant to the electronic trading industry with my company 
Aditat. Previous to this, I was President of Orc Software North America and 
President of Cameron Systems. I was co-chair of the FIX Protocol Americas 
Committee and member of the Global Steering Committee 2005-2007.

My submission is limited to only the data protocol used and is a recommendation 
that the SEC mandates that the FIX data protocol be used for the proposed 
Consolidated Audit Trail System.

The Financial Information Exchange (FIX) protocol is an industry driven 
protocol for electronic trading. It is now the global industry standard and has 
been a great success within the securities industry in the last 15 years. FIX 
is used in equities, foreign exchange, fixed income, commodities, and 
derivative markets. FIX is used by the buy side, sell side and exchanges. It is 
a global standard, being the dominant protocol in all major European and most 
major Asian markets. Its usage is governed by the industry run non-profit FIX 
Protocol Ltd (http://www.fixprotocol.org). A list of buy and sell side members, 
plus exchanges, is available at http://www.fixprotocol.org/members/. Please 
note that though this list is large it is not exhaustive, as firms do not need 
to be a member to use the protocol.

Nearly all pre-trade, trade, and some post-trade messages that are sent between 
the buy side, sell side and exchanges are sent using the FIX protocol. FIX is 
used for indications of interest, quotes, orders, basket/list orders, 
cancel/replace orders, executions and allocations. Many brokers also use the 
FIX protocol for routing messages within their organization. The FIX protocol 
already captures most of the information that the Consolidated Audit Trail 
System hopes to capture, including timestamp, side, quantity, type of order, 
client order ID, account, order handling instructions, desk received, and stock 
locate for short sales.  If any extra data needs to be captured for the 
Consolidated Audit Trail System this can be easily done by adding new fields to 
the protocol, which the FIX Protocol organization often does.

The advantages of using the FIX Protocol for the Consolidated Audit Trail 
System are:

a.      Lower Costs to the Industry – Buy side, sell side and exchanges already 
communicate and store messages using the FIX protocol. Costs to develop systems 
to store and communicate trading information to the SEC or SROs would be lower 
using FIX as the data already exists in a suitable format today. 

b.      Less Error and Easier Auditing – As records are currently kept using 
the FIX protocol, if any other protocol is used a translation is required to 
transform data into a different protocol. This introduces error and offers the 
potential for manipulation of the data. Using FIX means the SEC is looking at 
the original format of the data.

c.      Real Time – All FIX messages are generated in real time for trading. 
The SEC could more easily attain a real time reporting system by using FIX.

d.      Ability to Co-ordinate Across Derivative Markets and Globally – Market 
events such as the May 6 flash crash require looking at not just historical 
equity data but also data from equity derivative markets and international 
markets. As the FIX protocol is dominant in other asset classes and derivative 
markets including equity index futures, equity futures, equity options, and 
global markets, regulators can more easily gain a broader view.  

e.      Ability to Use Established Knowledge and Vendor Base – All buy side and 
sell side firms and exchanges today have experience working with the FIX 
protocol. There are thousands of business analysts, developers and consultants 
with in depth experience. There are hundreds of suppliers with products that 
communicate, monitor and manage the FIX protocol. These products range from 
free open source to robust vendor solutions. Using the FIX protocol will allow 
the SEC, SROs and firms to use this established experience and vendor base.

Currently some of the scope of the Consolidated Audit Trail System is captured 
in FINRA’s Order Audit Trail System (OATS) and the NYSE’s Order Tracking System 
(OTS). It is worthwhile to use many of the processes around data requested and 
the data transmission between brokers and the SRO from these systems. However 
the advantage of moving to FIX protocol instead of using one of the custom data 
protocols that these systems use is that the data is first in FIX and therefore 
requires no translation ensuring accuracy. FIX is in real time, while these 
custom data protocols are used for end of day reporting. Using a custom data 
protocol means that the data will not be as easily compared with data from 
derivatives and international markets that use FIX. And using a custom protocol 
will forever silo understanding of the data in the protocol within the limited 
number of people who focus on regulatory and compliance issues at securities 
firms. The entire global securities industry uses FIX, while only the 
regulatory and compliance departments at US equity brokers understand the OATS 
or OTS data format.

FIX is currently used to support regulations from FINRA, CFTC, SEC and 
internationally from the Investment Industry Regulatory Organization of Canada 
(IIROC) and the Australian Securities and Investment Commission (ASIC). An 
overview of this regulatory support is at: 
http://www.fixprotocol.org/regulations/.

For clarity, the FIX protocol has two parts. The application layer governs the 
data format (what the data looks like) and is what this recommendation is 
focused on. The session layer governs the transport of the messages (how the 
messages are sent between firms). While the session layer could be used for 
sending the messages from firms to the SRO, there may be other ways of sending 
the messages that are just as suitable.

Thank you for consideration of this submission. 

Sincerely,


Martin Koopman
