In early 2007, the CBOE Stock Exchange (CBSX) was created by the Chicago Board Options Exchange and four market-maker partners as a fully electronic market with a strict price-time priority matching algorithm and high-liquidity rebates for dedicated liquidity providers.

Today, CBSX operates as a facility of Chicago Board Options Exchange (CBOE) and uses CBOE's technology platform. CBSX (www.cbsx.com) is owned by CBOE and a consortium of financial entities.

The CBSX multi-asset trading model was initially designed to increase the efficiency of trading combined stock and options orders, while reducing execution costs for market participants.

With a new strategic initiative, on July 1, 2011, CBSX moved its trading operations to the East Coast from Chicago and began trading from the Equinix NY4 Internet Business Exchange datacenter in Secaucus, NJ. CBSX's move to the NY4 facility was intended to increase execution speed for the majority of CBSX's customers, which are located on the East Coast.

As part of that initiative, one month prior to the move to New Jersey, on June 1, 2011, CBSX instituted a simplified pricing model with identical fees for both liquidity "makers" and liquidity "takers" trading on CBSX, making CBSX the only U.S. exchange to use identical pricing for both makers and takers of market liquidity. The new CBSX pricing model is also one of the most economical fees structures currently available in the securities industry.

In the new CBSX pricing model, the fee for stocks trading above $1.00 is $0.0002 per share, and for stocks below $1.00, the fee is 0.02 percent of the dollar value of the transaction. In standard maker-taker market models, fees are generally different for those who make market liquidity and for those who take liquidity from the market.

As of July 2011, about 7,600 stocks were listed.

On March 5, 2007, CBSX was created by CBOE in partnership with four liquidity-providing firms: Interactive Brokers Group, LLC; LaBranche & Co Inc.; Susquehanna International Group, LLP; and VDM Specialists, LLC. All are dominant NYSE specialists. CBSX established a nine-person board, with members of these firms serving as part of the board constituency.

On opening day, CBSX launched an initial roster of 12 stocks, with plans to list 2,800 of the most actively traded New York Stock Exchange, NASDAQ Stock Market, and American Stock Exchange listed securities, exchange traded funds (ETFs), and other listed securities. By summer's end 2007, that goal was achieved, with roughly 2,900 listings on the exchange and climbing. (See CBSX stock listings and rollout schedule)[1]
