VOLUME 20 - BULLETIN #200

TO:	ALL CLEARING MEMBERS
FROM:	BUSINESS SYSTEMS GROUP
DATE:	July 12, 2000
SUBJECT:	Eurex Simulation Testing

The Eurex CBOT® Alliance will begin simulation testing on Monday, July 17, 2000. In preparation for this testing, the Clearing Corporation would like to remind participating firms of changes involved with the implementation of Eurex.

Eurex Changes

Exchange Codes

Project A afternoon and overnight trades are available in the OTIS® system under exchange 51. CBOT- Eurex trades will be processed under exchange 01.

Record IDs

Currently, record IDs are assigned to trades by either the firm (for regular trades) or the CBOT (for Project A® trades). CBOT - Eurex trades will have record ID numbers assigned by the Clearing Corporation. The record ID range will remain between 60000 and 74999.

Electronic Trading System Codes

All screens and reports that list trades under PJA, Proj A, or Project A will be replaced with ‘ETS’ (for Electronic Trading System). In addition, the Trade ID Source Code (positions 146 to 148) and the Business Cycle Code (positions 180 to 184) in the TREX Main Block will contain a value of ‘ETS’ for Eurex trades.

Real-Time Feeds

The Clearing Corporation will no longer create automatic hourly and end-of-session RJE duplication files of electronic trades. Firms will receive pre-edited real time feeds of CBOT- Eurex trades via MQ Series in the TREX record format. The elimination of Remote Job Entry (RJE) is necessary to support the implementation of the Clearing Corporation’s new customer network.

Because the trades sent to firms have not passed the Clearing edit process, there is a possibility that firms may have trades in bookkeeping that edit in clearing. Firms should check the Options Transaction Edit Report (TER0001) and the Futures Transaction Edit Report (TER0014) to view these edited trades.

The real-time feeds will begin shortly after 10:00 P.M. with trades designated as exchange 01. Due to the timeframe during which this trade information is generated

and the exchange designation, firms are cautioned to make sure these trades are excluded from the current day’s bookkeeping processing schedule.

Account Number Justification and Masking on Real-time Feeds

Customer account numbers will NOT be masked or right or left justified before they are sent to firms in the real time feeds. BOTCC® will pass account numbers along exactly as they were entered on the CBOT-Eurex GUI screens.

Trading Hours and Exchange Code

Currently Exchange 51 Project A trades from 2:15 P.M. until 4:30 Monday through Thursday and from 6:00 P.M. until 5:00 A.M. Sunday through Friday. Also, Side-By-Side Exchange 01 Project A trades between 5:30 A.M. and 2:00 P.M. Monday through Friday.

The new trading hours for the Eurex-CBOT system will be 10:00 P.M. until 4:00 P.M. the next day, Sunday through Friday. Trades executed after 10:00 P.M. will be for the next business day: for example, a trade entered at 11:00 P.M. on the 15^th will have a trade date of the 16^th.

Testing Simulation Support

During simulation testing, participating firms will be provided with real-time feeds of pre-edited trades via MQ in the TREX record format. These ‘pre-edited trades will be routed to the firm’s remote test queue. These trades can be identified by a record ID range of 60000-74999.

After each simulation, the Clearing Corporation will produce test Trade Registers which will be delivered to firm lock boxes. Test Register Datafiles will also be available. Please complete the attached form and return it to the Business Systems Group at fax number
