Open outcry is the name of a method of communication between professionals on a stock exchange or futures exchange. It involves shouting and the use of hand signals to transfer information primarily about buy and sell orders.2 The part of the trading floor where this takes place is called a pit.
In an open outcry auction, bids and offers must be made out in the open market giving all participants a chance to compete for the order with the best price. New bids or offers would be made if better than previous pricing for efficient price discovery. Exchanges also value positions marked to these public market prices on a daily basis. In contrast, over-the-counter markets are where bids and offers are negotiated privately between principals.
Examples of markets which use this system in the United States are the New York Mercantile Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade, and the Chicago Board Options Exchange. In the United Kingdom, the London Metal Exchange still makes use of open outcry.
The open outcry system is being replaced by electronic trading systems (such as CATS and Globex). The supporters of electronic trading claim that they are faster, cheaper, more efficient for users, and less prone to manipulation by market makers and broker/dealers. However, many traders advocate for the open outcry system on the basis that the physical contact allows traders to speculate as to a buyer/seller's motives or intentions and adjust their positions accordingly. Today, most stocks and futures contracts are no longer traded using open outcry due to the lower cost of the aforementioned technological advances.
Floor trading is where traders or stockbrokers meet at a specific venue referred to as a trading floor or pit to buy and sell financial instruments using open outcry method to communicate which each other. These venues are typically stock exchanges or futures exchanges and transactions are executed by members of such an exchange using specific language or hand signals. During the 1980s and 1990s phone and electronic trading replaced physical floor trading in most exchanges around the world.
As of 2007 few exchanges still have floor trading. One example is the New York Stock Exchange (NYSE) which still executes a small percentage of its trades on the floor. That means that the traders actually form a group around the post on the floor of the market for the specialist, someone that works for one of the NYSE member firms and handles the stock. Just like in an auction, there are shouts coming from those that want to sell and those that want to buy. The specialist facilitates in the match and centralizing the trades.
On 24 January 2007, the NYSE went from being strictly an auction market to a hybrid market that encompassed both the auction method and an electronic trading method that immediately makes the trade electronically. A small group of extremely high-priced stocks isn't on this trading system and is still auctioned on the trading floor.
Even though over 82 percent of the trades take place electronically, the action on the floor of the stock exchange still has its place. While electronic trading is faster and provides for anonymity, there's more opportunity to improve the price of a share if it goes to the floor. Investors maintain the right to select the method they want to use.when?
Traders usually flash the signals quickly across a room to make a sale or a purchase. Signals that occur with palms facing out and hands away from the body are an indication the gesturer wishes to sell. When traders face their palms in and hold their hands up, they are gesturing to buy.
Numbers one through five are gestured on one hand, and six through ten are gestured in the same way only held sideways at a 90 degree angle (index finger out sideways is six, two fingers is seven, and so on). Numbers gestured from the forehead are blocks of ten, and blocks of hundreds and thousands can also be displayed. The signals can otherwise be used to indicate months, specific trade or option combinations, or additional market information.
These rules may vary among exchanges or even among floors within the same exchange; however, the purpose of the gestures remains the same.

Since the 1980s, Nymex had a virtual monopoly on 'open market' oil futures trading, but the electronically based IntercontinentalExchange (ICE) began trading oil contracts that were extremely similar to Nymex's in the early 00s and Nymex began to lose market share almost immediately. The pit-traders at Nymex had been resisting the electronic move for decades, but the executives believed the exchange had to move to the electronic format, or it would cease to exist as a viable business. The executives introduced CME's Globex system into Nymex in 2006.7
