The Chicago Stock Exchange is a national securities exchange and market for the trading of equity securities.
The Chicago Stock Exchange was established in 1882, and would eventually merge with the exchanges of St. Louis, Cleveland and Minneapolis/St. Paul to form the Midwest Stock Exchange in 1949. By 1959 the New Orleans Stock Exchange had joined the Midwest Stock Exchange as well. In 1993 the exchange changed its name back to the Chicago Stock Exchange.
CHX operates a fully electronic Matching System, providing routing to CHX Institutional Brokers and off-Exchange market makers. The system was designed to provide broker/dealers with cost effective executions. Stocks eligible for trading in the CHX Matching System include NYSE, AMEX and NASDAQ-listed securities.
On securities priced $1.00 or above, the Chicago Stock Exchange generally charges a fee for removing liquidity, and provides a rebate for adding liquidity. Orders are matched in price-time priority.
