Change in CME Globex Match Algorithm for CBOT Dow Jones Industrial Average Index Futures Spread Transactions, CBOT Dow Jones US Real Estate Index Futures, CME Options on Yen Denominated Nikkei Stock Average Futures and CME Master Limited Partnership Futures

Effective Sunday, September 21, 2014 for trade date Monday, September 22, 2014, and pending all relevant CFTC regulatory review periods, The Board of Trade of the City of Chicago, Inc. (CBOT) and Chicago Mercantile Exchange Inc. (CME) will amend CBOT and CME Rules 580 (CME Globex Trading Matching Algorithms) to change the CME Globex trade match algorithm for the following six (6) Stock Index contracts:

The CME Globex match algorithm for spreads trades on three (3) CBOT Dow Jones Industrial Average (DJIA) Index futures contracts will change from Pro Rata with TOP and Mix/Max (Pro Rata) to First In First Out (FIFO). 

The CME Globex match algorithm for outright and spreads trades on CBOT Dow Jones US Real Estate Index futures contracts will change from FIFO with Lead Market Maker (LMM) to FIFO. 

The CME Globex match algorithm for outright and spreads trades on CME Master Limited Partnership Index futures contracts will change from split FIFO/Pro Rata to FIFO. 

The CME Globex match algorithm for trades on CME Options on Yen Denominated Nikkei Stock Average futures contracts will change from split FIFO/Pro Rata to FIFO. 

Currently, the CME Globex match algorithm for all other CME and CBOT stock index futures outright and spread trades and options on futures trades is FIFO. 

The change in the CME Globex match algorithm for these six (6) Stock Index contracts will establish the same CME Globex trade match algorithm for all CME and CBOT stock index futures outright and spread transactions and CME and CBOT options on futures transactions, i.e. a FIFO trade match algorithm.
