NYSE Euronext has said that its US options exchanges, NYSE Arca and NYSE Amex options have completed the first phase of a technology upgrade program that will double capacity for both exchanges.

The initial phase of the capacity expansion program was completed in the fourth quarter of 2010. The final phases of the program are anticipated to finish in the second quarter of 2011, following the first-quarter 2011 migration of NYSE Euronext’s US options exchanges to its Liquidity Center in Mahwah, New Jersey.

Upon completion of the capacity upgrade, both exchanges will be capable of processing one million orders and 8.4 million quotes per second with sub millisecond average acknowledgment (ACK) times, up from 500,000 orders and 4.2 million quotes previously.

NYSE Euronext US options’ migration to the Universal Trading Platform is expected to deliver a range of customer benefits, including the ability to quickly launch new trading applications that support distinct market structures and faster time to market for new functionality and performance improvements.

NYSE Euronext’s US options exchanges, NYSE Arca and NYSE Amex options utilize open-outcry trading facilities with advanced electronic trading platforms.

NYSE Arca Options co-CEO Amy Farnstrom said technology performance is critical to meeting our stringent regulatory and business performance demands.

"By independently deciding to double our capacity, we believe that we are again providing unique value to our customers and further differentiating NYSE Euronext’s US options exchanges," Farnstrom said.
