., Interactive Brokers), and have set up a good operating environment (at first, nothing more than a computer, a high-speed Internet connection, and a real-time newsfeed). You are almost ready to execute your trading strategy—after you have implemented an automated trading system (ATS) to generate and transmit your orders to your brokerage for execution. This chapter is about building such an automated trading system and ways to minimize trading costs and divergence with your expected performance based on your backtests. A WHAT AN AUTOMATED TRADING SYSTEM CAN DO FOR YOU An automated trading system will retrieve up-to-date market data from your brokerage or other data vendors, run a trading algorithm to generate orders, and submit those orders to your brokerage for execution. Sometimes, all these steps are fully automated and implemented as one desktop application installed on your computer.

Even if your brokerage’s API provides an order submission function for your use in an Excel Visual Basic macro, its speed is usually too slow if you have to run this program frequently in order to capture the latest data and generate wave after wave of orders. In this case, one must build a fully automated trading system. Building a Fully Automated Trading System A fully automated trading system (see Figure 5.2) can run the trading algorithm in a loop again and again, constantly scanning the latest prices and generating new waves of orders throughout the trading day. The submission of orders through an API to your brokerage account is automatic, so you would not need to load the trades to a basket trader or spread trader, or even manually run a macro on Real-time data feed Your proprietary desktop C++ program Desktop API from your brokerage Your brokerage account FIGURE 5.2 Fully Automated Trading System P1: JYS c05 JWBK321-Chan September 24, 2008 Execution Systems 13:55 Printer: Yet to come 85 your Excel spreadsheet.

Electronic trading systems are cheaper to operate because they do not require floor brokers and sales brokers. 27.8 SUMMARY Floor-based trading systems and automated trading systems have different strengths and weaknesses. Consequently, they appeal to different clienteles. It is unlikely that one market structure will dominate all trading. Table 27-1 summarizes strengths and weaknesses of floor-based and automated trading systems. Fully automated systems are very fast and generally cheap to use and operate. These characteristics ensure that active markets and markets that serve small traders will use automated trading systems extensively. In the U.S. equities markets, Bernard L. Madoff Investment Securities, Knight Capital Markets, and other dealers who offer automated execution systems provide excellent service to high volumes of small traders.

How does it depend on the ability of the new market to charge traders for the additional benefits that they receive? • The proponents of CISC and RISC microprocessors compete with each other in the marketplace. How does their competition differ from the competition among markets for order flow? 27 Floor Versus Automated Trading Systems Advances in communications and computing technologies now allow exchanges to completely automate their trading systems. Many exchanges have done so, and many brokers, ECNs, and dealers have created automated trading systems. Despite these developments, many of the most liquid exchanges in the world still employ floor-based trading systems. The New York Stock Exchange, the Chicago Board of Trade, the Chicago Mercantile Exchange, the New York Mercantile Exchange, and almost all U.S. options exchanges primarily use floor-based trading systems.

The electronic International Securities Exchange obtained a 16 percent share of U.S. equity option trading in the issues it trades, within 18 months of its 2000 launch. However, it has not yet displaced the traditional floor-based options markets. The most successful electronic competitors of the NYSE have been third market dealers, like Bernard L. Madoff Investment Securities and Knight Capital Markets. Their automated trading systems provide very quick service primarily to retail traders represented by discount brokers. * * * ▶ The Bangladeshi Stock Exchange and the New York Stock Exchange In 1999, the Bangladeshi Stock Exchange replaced its trading floor with an automated trading system. At the same time, the New York Stock Exchange considered where to build a new trading floor. The continued commitment of the New York Stock Exchange to its trading floor may be its most important decision at the turn of the millennium. The members and officers of the Exchange are fully aware of its significance.

The capacity to improve the forecast of earnings surprises and abnormal return using a mixture of well-known economic indicators with social network variables also enriches the debate between the modern finance theory and behavioral finance to show how behavioral patterns can be recognized with a rigorous method of analysis and forecast. 3.4.2 ALGORITHMIC TRADING The transformation of the major stock exchanges into electronic financial markets has encouraged the development of automated trading systems in order to process large amounts of information and make instantaneous investment decisions. Automated trading systems have a long tradition on classical artificial intelligence approaches such as expert systems, fuzzy logic, neural networks, and genetic algorithms. Trippi and Turban (1990, 1993), Trippi and Lee (2000), Deboeck (1994), and Chorafas (1994) have reviewed these early systems. Goonatilake and Treleaven (1995) survey an application of the above methods to automated trading and several other business problems such as credit risk, direct marketing, fraud detection, and price forecasting. Automated trading systems include a backtest or simulation module. In this respect, agent-based models could be useful to explore new ideas without risking any money.11 The Santa Fe stock market model (Arthur et al., l997; LeBarone et al., l998; LeBaron, 2001) has inspired many other agent-based financial market models such as Ehrentreich (2002)’s, which is based on the Grossman and Stiglitz (1980) model.

LeBaron (1998) applied bootstrapping to capture arbitrage opportunities in the foreign exchange market and then used a neural network where its network architecture was determined through an evolutionary process. Finally, Towers and Burgess (2000) used principal components to capture arbitrage opportunities. Creamer and Freund (2007, 2010a) follow the tradition of the papers in this section that use machine learning algorithms to find profitable trading strategies and also build completely automated trading systems. The authors use very well-known technical indicators such as moving averages or Bollinger bands. Therefore, the capacity to anticipate unexpected market movements is reduced because many other traders are expected to be trying to profit from the same indicators. However, the authors reduce this effect because the algorithms try to discover new trading rules using Logitboost instead of following the trading rules suggested by each indicator.

Additionally, transaction costs play a central role to raise performance. Instead of an automatic rebalance of the 66 CHAPTER 3 Using Boosting for Financial Analysis and Trading portfolio, the results of the PLAT competition indicate that if the CRP strategy is implemented only with limit orders, its results improve because of the rebates. Creamer and Freund (2010a) propose a multistock automated trading system. The system is designed to trade stocks, and relies on a layered structure consisting of ADT, which is implemented with Logitboost, as the machine learning algorithm; an on-line learning utility; and a risk management overlay.12 The system generates its own trading rules and weighs the suggestion of the different ADTs or experts to propose a trading position. Finally, the risk management layer can validate the trading signal when it exceeds a specified nonzero threshold and limit the use of a trading strategy when it is not profitable.

When Berlekamp explained his firm’s methods to business students on Berkeley’s campus, some mocked him. “We were viewed as flakes with ridiculous ideas,” Berlekamp says. Fellow professors were polite enough not to share their criticism and skepticism, at least within earshot. But Berlekamp knew what they were thinking. “Colleagues avoided or evaded commenting,” he says. Simons didn’t care about the doubters; the gains reinforced his conviction that an automated trading system could beat the market. “There’s a real opportunity here,” he told Berlekamp, his enthusiasm growing. Medallion scored a gain of 55.9 percent in 1990, a dramatic improvement on its 4 percent loss the previous year. The profits were especially impressive because they were over and above the hefty fees charged by the fund, which amounted to 5 percent* of all assets managed and 20 percent of all gains generated by the fund.

Rivals didn’t have self-improving models; Renaissance now had a secret weapon, one that would prove crucial to the fund’s future success. Eventually, Brown and Mercer developed an elaborate stock-trading system that featured a half million lines of code, compared to tens of thousands of lines in Frey’s old system. The new system incorporated all necessary restrictions and requirements; in many ways, it was just the kind of automated trading system Simons had dreamed of years earlier. Because the Nova fund’s stock trades were now less sensitive to the market’s fluctuations, it began holding on to shares a bit longer, two days or so, on average. Crucially, Brown and Mercer retained the prediction model Frey had developed from his Morgan Stanley experience. It continued to identify enough winning trades to make serious money, usually by wagering on reversions after stocks got out of whack.

“This interconnectedness is hard to model and predict with accuracy, and it changes over time. RenTec has built a machine to model this interconnectedness, track its behavior over time, and bet on when prices seem out of whack according to these models.” Outsiders didn’t quite get it, but the real key was the firm’s engineering—how it put all those factors and forces together in an automated trading system. The firm bought a certain number of stocks with positive signals, often a combination of more granular individual signals, and shorted, or bet against, stocks with negative signals, moves determined by thousands of lines of source code. “There is no individual bet we make that we can explain by saying we think one stock is going to go up or another down,” a senior staffer says. “Every bet is a function of all the other bets, our risk profile, and what we expect to do in the near and distant future.

As I wrote in one of my blog posts recently, I don’t intend on being Dick Van Dyke, the guy who trips over the ottoman every time. I plan on being the guy that walks around the ottoman next time. CHAPTER 13 Charles German While his career began more than twenty years ago on the floor of the Chicago Board of Trade, Charles German explains that his adoption of a trend-following strategy in 2005 was what ultimately led him to reach new heights in trading. He now uses an automated trading system that combs the markets for setups, places entry and stop orders, and executes with little or no human interaction required. While fully automated trading may be a dream for many traders, it was only through thousands of hours of meticulous backtesting and some costly, difficult lessons learned along the way that German made it a reality. By requiring that his strategy work in all markets and market conditions, he eliminates the need to chase trades or the flavor-of-the-day setup or strategy.

Menaker: That’s a really good question, and I’ve personally gone back and forth on that myself over the years—paying attention to the news or not paying attention to the news—and I think people can succeed going both ways. What I will tell you, though, is that there are hedge funds that are scraping social media, like Twitter and even Facebook, and they are scraping CNBC and Bloomberg for keywords and sentiment. Then they will apply that to an automated trading system. That’s happening more and more. I was in Japan in June for a hedge fund conference, and I met a Tokyo University professor there who’s a financial engineer. He showed me how he and some other guys were starting up a hedge fund using this model that I just explained, and they thought they were the first to do this. And I said, “Actually, no, there are six or seven funds in the United States that I know of that have already been doing that in the last three or four years, and there are probably more than those six or seven.

Underneath the surface, however, changes in how Wall Street was paying for analysts would change the game in subtle ways. Some of it had to do with those over-the-counter traders not answering their phones. Wall Street got sued for not answering phones and the SEC insisted the Street put in a system known as Small Order Execution System, SOES. This automated execution of small orders would lead to day traders and would eventually lead to automated trading systems known as ECNs. These ECN trading systems would represent over half of overthe-counter trades by 2001, with commissions a hundredth of what they had been in 1987. It changed the way Wall Street gets paid. Commissions were toast. Banking fees would replace commissions, and eventually kill research in the process. · · · For the rest of the year, everyone was in shock.

He has taught various computer science courses for the past ten years in the University of Chicago, NYU and Columbia University. His main passion is technology but he is also a scuba diving instructor and an experienced rock-climber. Sourav Ghosh has worked in several proprietary high-frequency algorithmic trading firms over the last decade. He has built and deployed extremely low latency, high throughput automated trading systems for trading exchanges around the world, across multiple asset classes. He specializes in statistical arbitrage market-making, and pairs trading strategies for the most liquid global futures contracts. He works as a Senior Quantitative Developer at a trading firm in Chicago. He holds a Masters in Computer Science from the University of Southern California. His areas of interest include Computer Architecture, FinTech, Probability Theory and Stochastic Processes, Statistical Learning and Inference Methods, and Natural Language Processing.

When designed and programmed correctly, they can execute instructions and algorithms extremely quickly, and can be scaled and deployed across a lot of instruments seamlessly. They are extremely fast at reacting to market data, and they don't get distracted or make mistakes (unless they were programmed incorrectly, which is a software bug and not a drawback of computers themselves). They don't have emotions, so don't deviate from what they are programmed to do. All of these advantages make computerized automated trading systems extremely profitable when done right, which is where algorithmic trading starts. Evolution of algorithmic trading – from rule-based to AI Let's take a simple example of a trend-following strategy and see how that has evolved from a manual approach all the way to a fully automated algorithmic trading strategy. Historically, human traders are used to having simple charting applications that can be used to detect when trends are starting or continuing.

MODEL DEVELOPMENT LIFE CYCLE High-frequency trading systems, by their nature, require rapid hesitationfree decision making and execution. Properly programmed computer systems typically outperform human traders in these “mission-critical” trading tasks, particularly under treacherous market conditions—see Aldridge (2009), for example. As a result, computer trading systems are rapidly replacing traditional human traders on trading desks around the world. The development of a fully automated trading system follows a path similar to that of the standard software development process. The typical life cycle of a development process is illustrated in Figure 16.1. A sound development process normally consists of the following five phases: 1. Planning 2. Analysis 3. Design 4. Implementation 5. Maintenance Planning Analysis Maintenance Design Implementation FIGURE 16.1 Typical development cycle of a trading system.

Starting in the 1980s, but really blossoming in the 1990s, finance got networked, and schemes were for the first time able to exceed the pre-digital limitations of human deception. The networking of finance occurred independently and in advance of the rise of the familiar Internet. There were different technical protocols over different infrastructure, though similar principles applied. Some of the early, dimly remembered steps toward digitally networked finance included: 1987’s Black Monday (a market anomaly caused by automated trading systems), Long-Term Capital, and Enron. I will not recount these stories here, but those readers who are not familiar with them would do well to read up on these rehearsals of our current global troubles. In all these cases there was a high-tech network scheme at play that seemed to concentrate wealth while at the same time causing volatility and trauma for ordinary people, particularly taxpayers who often ended up paying for a bailout.

He sent out his résumé to headhunters. But this time he wanted a real technology company, not another Wall Street firm. One of the headhunters called him and said, “I know you said you would kill me if I even proposed the finance thing, but there’s this opportunity that’s actually a very unusual financial company.” That company was D. E. Shaw. It was founded in 1988 by David Shaw to create a newfangled computer-automated trading system for Wall Street. Shaw was a computer science professor at Columbia University who was lured to Wall Street to help computerize stock trading systems, and then started his own company. At the time, computer software was already being used to track small differences in stock prices around the world, allowing arbitrageurs to buy the stock at one price and immediately sell it for a profit at the higher price.

Nevertheless, Knight was a key player in the U.S. stock market, executing 17 percent of all trades on the New York Stock Exchange and NASDAQ. Their slogan was, “The Science of Trading, the Standard of Trust.” Like many high-frequency trading firms, their business was lucrative. On the morning of July 31, 2012, Knight had $365 million in assets. Within 45 minutes, they would be bankrupt. At 9:30 a.m. Eastern Time on July 31, U.S. markets opened and Knight deployed a new automated trading system. Instantly, it was apparent that something was wrong. One of the functions of the automated trading system was to break up large orders into smaller ones, which then would be executed individually. Knight’s trading system wasn’t registering that these smaller trades were actually completed, however, so it kept tasking them again. This created an endless loop of trades. Knight’s trading system began flooding the market with orders, executing over a thousand trades a second.

There also was a David-and-Goliath effect: the scrawnier traders with the intellectual know-how, though perhaps not the athletic prowess that had once dominated the pits, were finally able to match wits against the brawnier traders, without fear of physical retribution. On Wall Street, the move to the screen was inciting a technological arms race among the banks and hedge funds, which began sinking millions of dollars into state-of-the-art automated trading systems that could move at near-lightning speeds, outpacing the floor traders, many of whom still traded with no more than paper and pencil. The New York floor traders, whose brutality had once crushed the Marine Corps officers, were now getting a dose of their own medicine on their home turf—and they did not like it. Bo Collins, the ex–Nymex president, rang up journalists from his hedge fund to tell them that ICE was beating Nymex.

Once on the screen, the energy traders in arcades around the world became so intent on hitting their financial targets, they lost sight of the potential human repercussions. The screens had desensitized them to what was happening on the ground. Any harm done to energy consumers in the crossfire of their trading games was blithely categorized as collateral damage. Banks and hedge funds, whose automated trading systems bought and sold millions upon millions of energy contracts in just milliseconds, followed the same credo. Computer programmers were being hailed as the new gunslingers of Wall Street, fetching breathtaking salaries. Veteran energy traders began reporting that some of the computerized trading systems were letting banks and funds trade on the screen in ways that would have been illegal in the pits.

These new fund managers take risks, with assurance that the companies they invest in provide accurate information, have liquid shares, trade cheaply and quickly and exist free of stock manipulation. These funds rarely own Russian gas refiners, as they fail all of the above assurances. But funds do own weird companies that make components for optical wave division multiplexing or some new biopharma company or the latest in supply chain management software, but they require automated trading systems to stay quick of foot. The New York Stock Exchange is still a people intensive exchange. Its specialist system was created in 1871. And we are still stuck with the NYSE monopoly on listed shares. Lots of reasons are offered, such as centralized pools of liquidity or orderly markets, etc. But also to blame are some subtle regulatory technicalities that the NYSE hides behind. One technicality is a network called the Intermarket Trading System, which was also set up in 1975, ostensibly to execute trades between exchanges.

If the intention is to increase staff and trading volume, as well as venture into different asset classes, a scalable in-house software solution may be the answer. 13.6 Conclusion The sell side will continue to undertake the difficult task of maintaining strong relationships with the buy side, which will allow them to grasp a foothold on market share. Major broker-dealers will enhance their market data infrastructure in order to translate large quantities of real-time data demanded by algorithmic and other automated trading systems for best execution. This will eliminate as much latency as possible. Direct market access companies, OMSs, and ECN aggregators will continue to be acquired by broker-dealers. Individual investors will put further pressure on their brokers and mutual fund managers for more transparency and to better understand management and operation fees. ECN aggregation is a natural progression and will continue to pressure the competition for desk space for the buy-side trader.

It was one of the first in a long line of automated trading systems spawned by the hedge-fund industry.26 Weymar was initially skeptical of Vannerson’s project.27 His trend-following concept seemed disarmingly simple: Buy things that have just gone up on the theory that they will continue to go up; short things that have just gone down on the theory that they will continue to go down. Even though Vannerson’s program took a step beyond that—it tried to distinguish upticks that might signify a lasting trend from upticks that signified nothing—Weymar still doubted that anyone could make serious money from something apparently so trivial. But by the summer of 1971, Weymar had reversed himself. The humiliation of the corn episode was one reason: The great virtue of an automated trading system was that risk controls had to be programmed into the computer from the start, and there was no danger of overconfident traders exceeding their allowed limits.

The market was so tilted in their favor that in March 2011, Credit Suisse saw a big business opportunity in launching a new kind of trading platform—an Electronic Communication Network (ECN) that had rules favoring institutional investors and disadvantaging high-frequency traders. The SEC was so out of touch with the markets, it actually believed that the consolidated tape was the best source of information for the best prices in a listed security, precluding the need for investors to subscribe to data feeds from each of the 10 exchanges and 70-plus automated trading systems (ATS).4 In fact, right under the SEC’s nose, a duel market had developed: a high-end market for the moneyed traders and a low-end, less efficient market for retail investors. The SEC never noticed until Saluzzi and Arnuk got its attention in 2009. Regulators also failed to grasp a more fundamental fact. Because the high-frequency traders were executing related trades simultaneously on all the stock venues and all the commodity venues, the equities and the commodities markets in effect had been unified.

A fourth investor was told, by three different banks, that they didn’t want to connect to IEX because they didn’t want to pay the $300-a-month connection fee. Of all the banks that dragged their feet after their customers asked them to send their stock market orders to IEX, Goldman Sachs had offered the best excuse: They were afraid to tell their computer system to do anything it hadn’t done before. In August 2013, the Goldman automated trading system generated a bunch of crazy and embarrassing trades that lost Goldman hundreds of millions of dollars (until the public exchanges agreed, amazingly, to cancel them). Goldman wanted to avoid giving new instructions to its trading machines until it figured out why they had ceased to follow the old ones. There was something about the way Goldman had treated Brad when he visited their offices—listening to what he had to say, bouncing him up the chain of command rather than out the door—that led him to believe their excuse.

New quants can easily be overwhelmed by the challenge of trying to develop alphas. They ask themselves, “How do I find alphas? How do I start the search?” Even experienced quants working with many alphas can miss key components required to build a robust, diversified portfolio. For instance, one of the most difficult aspects of alpha portfolio construction is the need to optimize the level of diversification of the portfolio. In automated trading systems, decisions on diversification make up a major area of human intervention. It’s not easy to visualize the many pieces of the portfolio, which contain hundreds or thousands of alphas, and their interactions. TAP emerged from those concerns. When new quants start conducting alpha research, many begin by searching the internet for articles about developing alphas. Most of those articles focus on reversion and momentum, and as a result, beginners may initially spend a lot of time building reversion or momentum alphas.

The consolidation of the regionals culminated in one major exchange, the New York Stock Exchange (NYSE); a handful of regionals, such as Boston, Philly and P-coast; and an over-the-counter (OTC) market, NASDAQ, for small growth issues. NASDAQ NASDAQ began trading as the world’s first electronic stock market in 1971. NASDAQ was an acronym for National Association of Securities Dealers Automated Quotation system and was member-owned by the National Association of Securities Dealers (NASD). What started as a bulletin board quotation system grew into a full stock market, as the NASDAQ added volume reporting and automated trade systems. Due to less stringent listing requirements, small startups would raise money via initial public offerings (IPOs) on NASDAQ as opposed to the NYSE. It is hard to believe, but Intel Corp. started out as a $6.8 million IPO and Microsoft as a $60 million IPO. Through NASDAQ, broker dealers competed with each other by providing two-sided quotes in each stock listed. Actual trades would predominantly be agreed to over the telephone.

Brokers and platforms If you are not running a fully automated trading system, I hesitate to recommend a specific broker. A key selection criteria is price. Estimate the expected annual total fee from how often you’re trading, in what size, and with what total account value. Then use this for comparison purposes. Equally important is whether you can trade the products you want and with leverage if needed. Customer service should be a factor, but it is hard to evaluate in advance.

The gloves were coming off. WHILE Maschler’s Datek traders were good at SOES, they had little edge over skilled competitors such as Houtkin. That quickly changed after Josh Levine began tinkering with Datek’s SOES trading system. Levine was still working at Russo and freelancing, but he started to poke around Datek’s operation at 50 Broad Street soon after he’d heard they’d been using an automated trading system. While he didn’t know the ins and outs of SOES at first, he quickly caught on—and liked what he saw. The greedy fat-cat insiders were getting their lunches eaten by Datek’s hit-and-run traders. It was a thing of beauty, a pristine example of how technology could shift the ground beneath the entrenched elite and transfer the power to their smarter, faster rivals. Datek’s grizzled traders at first didn’t know what to make of the slight, baby-faced programmer named Josh.

For example, virtually all of Wall Street's records are in electronic form and a computer system attack could cause serious problems, including potentially large financial losses. The financial networks of the world are interconnected in a relatively fragile way. A problem in the trading systems of one firm can cause a cascade effect in the world markets. In spring of 2010 the U.S. stock markets experienced a “Flash Crash” during which the Dow Jones stock index sunk by 1,000 points within five minutes before quickly recovering. During this time, automated trading systems piled on sell orders, making the problem escalate quickly before finally coming back under control (some investors who had set stop losses in their accounts took large losses as they were automatically traded out of positions that recovered almost immediately and other bad trades were later backed out and canceled). The Flash Crash was reportedly caused by a combination of automated and high-frequency trading systems gone awry.

Ninety percent of billionaires in finance with MBAs got their degrees from only three Ivy League schools: Harvard, Columbia, and the University of Pennsylvania.11 All of this education has reshaped the culture of finance. Back in the fabled 1980s, the flood of MBAs onto Wall Street was just beginning, and many top earners made do with BAs. Things changed as c01.indd 24 5/11/10 6:17:19 AM educated, rich, and liberal 25 finance became more complicated—as “quants” found new ways to make money using statistical techniques and algorithms, as automated trading systems came online, and as new financial products for managing risk or structuring debt, such as derivatives, came into being. Top universities spat out PhDs in fields such as mathematical finance and computational finance. Newly created master’s programs sprang up in financial engineering. MBA programs bolstered their quantitative offerings. More lawyers went into finance, applying their legal skills to the ever more complex deals that were going on.

Tuttle’s physics background gave him the tools to understand many of the complex trades PDT executed. But since he didn’t have any computer programming skills, it limited his ability to design and implement models. Instead, he became PDT’s “human trader.” At the time, there were still certain markets, such as stock index futures, that weren’t fully automatic. Trades spat out by PDT’s models had to be called in over the telephone to other desks at Morgan. That was Tuttle’s job. The automated trading system didn’t always go smoothly. Once PDT mistakenly sold roughly $80 million worth of stock in about fifteen minutes due to a bug in the system. Another time Reed, who was running the Japanese stock system at the time, asked another trader to cover for him. “Just hit Y every time it signals a trade,” he said. He failed to mention the need to also hit enter. None of the trades went through properly.

Think about financial trading. In time, fewer trades will be executed by screaming stockbrokers on trading floors, and more by intelligent trading algorithms that respond to market events at lightning speed. There used to be 600 US cash equities traders at Goldman Sachs’ headquarters in New York. Now there are just two. One-third of the bank’s staff are computer engineers.6 The introduction of automated trading systems has made financial regulation a nightmare for human officials. The algorithms are often too fast, too complex, and too adaptable to be subject to human oversight. OUP CORRECTED PROOF – FINAL, 26/05/18, SPi РЕЛИЗ ПОДГОТОВИЛА ГРУППА "What's News" VK.COM/WSNWS Force 103 Increasingly, the most practical method of enforcing the law is through the use of other algorithms programmed to detect and prohibit errant behaviour, or at least flag it for human attention.7 One of the digital systems being used to keep tabs on financial behaviour is a version of IBM’s Watson.8 The idea of digital law enforcement may seem weird but it doesn’t really disrupt our notion of what the law is.

In 2006, the NYSE became an electronic exchange, saying goodbye to the traditional floor brokers and specialists who ran around on those old wooden floors, screaming prices as they went.2 Stock purchases and sales can be completed through a variety of networks: a national exchange such as the NYSE, an electronic communication network (ECN), a large broker-dealer, or a dark pool. Most trading—64%—takes place on the exchanges. Broker-dealers account for another 18%, about 10% occurs through ECNs, and the remaining 8% occurs in dark pools.3 The exchanges consist of highly automated trading systems that respond to stock orders in less than one millisecond. ECNs are alternative trading systems that offer services that are very similar to those offered by the exchanges. They try to match buyers and sellers at the best bid and offer prices. All the trades that occur on the exchanges and the ECNs must be posted on the consolidated tape, including price and quantity traded.4 The consolidated tape is a real-time history of every trade in the U.S. markets.
