NYSE MKT
NYSE MKT completed its acquisition of the American Stock Exchange (Amex) in October of 2008. Post-merger, the Amex equities business was renamed NYSE Amex. NYSE Amex Options is the options trading facility of NYSE MKT.
Long before it was called the American Stock Exchange, Amex was known as the "Curb Market" because trading was conducted by the curb on Broad Street, near the well-established New York Stock Exchange.
In 1921, the Curb moved indoors to a building on Greenwich Street in lower Manhattan and by 1930 was considered the leading international stock market, listing more foreign issues than all other U.S. securities markets combined. In 1953, The New York Curb Exchange changed its name to the American Stock Exchange.
NYSE Amex operates under the NYSE market structure to provide a venue for listing and trading of small- and micro-cap companies. The venue operates in adherence with the NYSE Amex Parity and Priority model. The market structure is similar to that of NYSE Euronext.
Stocks traded on NYSE Amex are assigned Designated Market Makers (DMMs), and one or more Supplemental Liquidity Providers (SLPs). Customers are charged a fee for removing liquidity, while liquidity providers receive a rebate. Transactions on NYSE Amex are cleared through the National Securities Clearing Corporation (NSCC).
NYSE Amex Options
NYSE Amex Options, the options trading facility of NYSE MKT, blends technology built on NYSE Arca architecture with an open-outcry trading floor. It is one of two US options marketplaces operated by NYSE Euronext for the trading of options.
NYSE Amex facilitates trading in contracts on domestic stocks, American Depository Receipts (ADRs), broad-based industry and sector indices, exchange-traded funds (ETFs) and HOLDRs. Customers may also trade LEAPs and FLEX Options.
Customers may trade either electronically through the Central Order Book, or via open outcry on the NYSE Amex Options trading floor. The floor facility provides a venue for broker-negotiated deals, large institutional and complex orders. The exchange offers a traditional pro-rata allocation model with payment for order flow.
Floor trading is complemented by an electronic trading system supported by NYSE Arca technology. NYSE Arca Options operates a price-time priority, maker/taker model.
All options contracts traded by NYSE Amex Options are cleared by the Options Clearing Corporation (OCC).
