A trading room gathers traders operating on financial markets. The trading room is also often called the front office. The terms "dealing room" and "trading floor" are also used, the latter being inspired from that of an open outcry stock exchange. As open outcry is gradually replaced by electronic trading, the trading room becomes the only remaining place that is emblematic of the financial market. It is also the likeliest place within the financial institution where the most recent technologies are implemented before being disseminated in its other businesses.

Specialized computer labs that simulate trading rooms are known as "trading labs" or "finance labs" in universities and business schools.

Origin Before the 1960s or 1970s, the banks' capital market businesses were mostly split into many departments, sometimes scattered at several sites, as market segments: money market (domestic and currencies), foreign exchange, long-term financing, exchange, bond market. By gathering these teams to a single site, banks want to ease: a more efficient broadcast of market information, for greater reactivity of traders. idea confrontation on market trends and opportunities. desk co-ordination towards customers.

Context The Trading Rooms first appeared among United States bulge bracket brokers, such as Morgan Stanley, from 1971, with the creation of NASDAQ, which requires an equity trading desk on their premises, and the growth of the secondary market of federal debt products, which requires a bond trading desk.

The spread of trading rooms in Europe, between 1982 and 1987, has been subsequently fostered by two reforms of the financial markets organization, that were carried out roughly simultaneously in the United Kingdom and France.

In the United Kingdom, the Big Bang on the London Stock Exchange, removed the distinction between stockbrokers and stockjobbers, and prompted US investment banks, hitherto deprived of access to the LSE, to set up a trading room in the City of London.

In France, the deregulation of capital markets, carried out by Pierre Bérégovoy, Economics and Finance Minister, between 1984 and 1986, led to the creation of money-market instruments, of an interest-rate futures market, MATIF, of an equity options market, MONEP, the streamlining of sovereign debt management, with multiple-auction bond issues and the creation of a primary dealer status. Every emerging market segment raised the need for new dedicated trader positions inside the trading room.

Businesses A trading room serves two types of business: trading, and arbitrage, a business of investment banks and brokers, often referred to as the sell side. portfolio management, a business of asset management companies and institutional investors, often referred to as the buy side. Brokers and investment banks set up their trading rooms first and large asset-management firms subsequently followed them.

The business type determines peculiarities in the organization and the software environment inside the trading room.

Organization Trading rooms are made up of "desks", specialised by product or market segment (equities, short-term, long-term, options...), that share a large open space.

An investment bank's typical room makes a distinction between: traders, whose role is to offer the best possible prices to sales, by anticipating market trends. After striking a deal with a sales, the trader arranges a reverse trade either with another trader belonging to another entity of the same institution or to an outside counterparty; market-makers, acting like wholesalers. Trades negotiated by market-makers usually bear standard terms.

Sales make deals tailored to their corporate customers' needs, that is, their terms are often specific. Focusing on their customer relationship, they may deal on the whole range of asset types.

Many large institutions have grouped their cash and derivative desks, while others, such as UBS or Deutsche Bank, for example, giving the priority to customer relationship, structure their trading room as per customer segment, around sales desks.

Some large trading rooms hosts offshore traders, acting on behalf of another entity of the same institution, located in another time-zone. One room in Paris may have traders paid for by the New York City subsidiary, and whose working hours are consequently shifted. On the foreign exchange desk, because this market is live on a 24/24 basis, a rolling book organisation can be implemented, whereby, a London-based trader, for instance, will inherit, at start of day, the open positions handed over by the Singapore, Tokyo, or Bahrain room, and manages them till his own end-of-day, when they are handed over to another colleague based in New York City.

Some institutions, notably those that invested in a rapid development (RAD) team, choose to blend profiles inside the trading room, where traders, financial engineers and front-office dedicated software developers sit side by side. The latter therefore report to a head of trading rather than to a head of IT.

More recently, a profile of compliance officer has also appeared; he or she makes sure the law, notably that relative to market use, and the code of conduct, are complied with.

The middle office and the back office are generally not located in the trading room.

The organisation is somewhat simpler with asset management firms: asset managers are responsible for portfolios or funds; "traders" are in contact with "brokers" – that is, with the above-mentioned investment banks' "sales"; however, this profile is absent from asset management firms that chose to outsource their trading desk.

The development of trading businesses, during the eighties and nineties, required ever larger trading rooms, specifically adapted to IT- and telephony cabling. Some institutions therefore moved their trading room from their downtown premises, from the City to Canary Wharf, from inner Paris to La Défense, and from Wall Street towards Times Square or New York City's residential suburbs in Connecticut; UBS Warburg, for example, built a trading room in Stamford, Connecticut in 1997, then enlarged it in 2002, to the world's largest one, with about floor space, allowing the installation of some working positions and monitors. The "Basalte" building of Société Générale is the first ever building specifically dedicated to trading rooms; it is fit for double power sourcing, to allow trading continuity in case one of the production sources is cut off. In the 2000s, JP Morgan was planning to construct a building, close to the World Trade Center site, where all six floors dedicated to trading rooms would be cantilevered, the available ground surface being only .

Infrastructure

The early years Telephone and teleprinter have been the broker's first main tools. The teleprinter, or Teletype, got financial quotes and printed them out on a ticker tape. US equities were identified by a ticker symbol made of one to three letters, followed by the last price, the lowest and the highest, as well as the volume of the day. Broadcasting neared real time, quotes being rarely delayed by more than 15 minutes, but the broker looking for a given security's price had to read the tape...

As early as 1923, the Trans-Lux company installed the NYSE with a projection system of a transparent ticker tape onto a large screen. This system has been subsequently adopted by most NYSE-affiliated brokers till the 1960s.

In 1956, a solution called Teleregister, came to the market; this electro-mechanical board existed in two versions, of the top 50 or top 200 securities listed on the NYSE; but one had to be interested in those equities, and not in other ones...

During the 1960s, the trader's workstation was remarkable for the overcrowding of telephones. The trader juggled with handsets to discuss with several brokers simultaneously. The electromechanical, then electronic, calculator enabled him or her to perform basic computations.

In the 1970s, if the emergence of the PABX gave way to some simplification of the telephony equipment, the development of alternative display solutions, however, lead to a multiplication of the number of video monitors on their desks, pieces of hardware that were specific and proprietary to their respective financial data provider. The main actors of the financial data market were; Telerate, Reuters, Bloomberg with its Bloomberg Terminal, Knight Ridder notably with its Viewtron offering, Quotron and Bridge, more or less specialised on the money market, foreign exchange, securities market segments, respectively, for the first three of them.

The advent of spreadsheets From the early 1980s, trading rooms multiplied and took advantage of the spread of micro-computing. Spreadsheets emerged with independent products released for MS-DOS/Windows platforms and Unix platforms. The IBM PCs of the early 1980s used Lotus 1-2-3,Lotus 1-2-3; used by a small percent of companies today but by 1989 it had been mostly superseded by Excel for workstations and terminals. For UNIX, there were Applix and WingzWingz; used by a small percent of companies today among others.

Excel quickly became popular among traders as a decision support tool to manage their position. This popularity encouraged the adoption of the Windows NT platform over other Unix or VAX/VMS platforms.

Though software alternatives multiplied during this decade, the trading room was suffering from a lack of interoperability and integration. To begin with, there was scant automated transmission of trades from the front-office desktop tools, notably Excel, towards the enterprise application software that gradually got introduced in back-offices; traders recorded their deals by filling in a form printed in a different colour depending on the direction (buy/sell or loan/borrow), and a back-office clerk came and picked piles of tickets at regular intervals, so that these could be re-captured in another system.

The digital revolution Video display applications were not only wrapped up in cumbersome boxes, their retrieval-based display mode was no longer adapted to markets that had been gaining much liquidity and henceforth required decisions in a couple of seconds. Traders expected market data to reach them in real time, with no intervention required from them with the keyboard or the mouse, and seamlessly feed their decision support and position handling tools.

The digital revolution, which started in the late 1980s, was the catalyst that helped meet these expectations. It found expression, inside the dealing room, in the installation of a digital data display system, a kind of local network. Incoming flows converged from different data providers,the feed of the main integrator, such as Reuters or Moneyline Telerate, typically complementing that of the local stock-exchange datafeed, like TOPCAC, in France, from Société de Bourse Française (SBF) and these syndicated data were distributed onto traders' desktops. One calls a feed-handler the server that acquires data from the integrator and transmits them to the local distribution system.

Reuters (TRIARCH 2000), Teknekron (TIB/TTRS), and Micrognosis (MIPS) soon entered this market. Their infrastructure provided the foundation for desktop applications that acquired, displayed, and graphically analyzed market data.

This type of software usually enables the trader to assemble the relevant information into composite pages, comprising a news panel, in text format, sliding in real time from bottom to top, a quotes panel, for instance spot rates against the US dollar, every quote update or « tick » showing up in reverse video during one or two seconds, a graphical analysis panel, with moving averages, MACD, candlesticks or other technical indicators, another panel that displays competitive quotes from different brokers, etc...
