Examples pair trading strategies



Pairs trading is a market-neutral trading strategy that matches a long position with a short position in a pair of highly correlated instruments such as two stocks, exchange-traded funds ETFscurrencies, commodities or options. It is rrading for pairs traders to profit during a variety of market conditions, including periods when the strayegies goes up, down or sideways, and during periods of either low or high volatility.

Algorithmic trading strategiea a method of executing a large order too large to fill all at once using automated pre-programmed trading instructions accounting for variables such as time, price, and volume [1] to send small slices of the order child orders out to the market over time. They were developed so that traders do not need to constantly watch a stock and repeatedly send those slices out manually.

Popular "algos" include Percentage of Volume, Pegged, VWAP, TWAP, Implementation Shortfall, Target Close. In the past several years algo trading has been gaining traction with both retails and institutional traders. Popular platforms for algorithmic trading include MetaTraderNinjaTrader, IQBroker, and Quantopian. Algorithmic trading is not an attempt to make a trading dtrategies.

It is simply a way to minimise the cost, market impact examplew risk in execution of an order. The term is also used to mean automated trading system. These do indeed have the goal of making a profit. Also known as black box tradingthese encompass trading strategies that are heavily reliant on complex mathematical formulas and high-speed computer programs.

Such systems run strategies including market makinginter-market spreading, arbitrageor pure speculation such as trend following. Many fall into the category of high-frequency trading HFTwhich are characterized by high turnover and high order-to-trade ratios. Algorithmic trading and HFT have resulted in a dramatic change of the market microstructureparticularly in the way liquidity is provided.

In MarchVirtu Financiala high-frequency trading firm, reported that during five years the firm as a whole was profitable on 1, out of 1, trading days, [12] losing money just one day, empirically demonstrating the law of large numbers benefit of trading thousands to millions of tiny, low-risk and low-edge examplees every trading day. Securities and Exchange Commission and the Examples pair trading strategies Futures Trading Commission said in reports that an algorithmic trade entered by a mutual fund company triggered a wave of selling that led to the Flash Crash.

As a examples pair trading strategies of these events, the Dow Jones Industrial Average suffered its second largest intraday point swing ever to that date, though prices quickly recovered. See List of largest daily changes forex systems that work the Dow Jones Industrial Average. A July, report by the International Organization of Securities Commissions IOSCOan international body of securities regulators, concluded that while "algorithms and HFT technology have been used by market participants to manage their trading and risk, their usage was also clearly a contributing factor in the flash crash event of May 6, One study found that HFT did not significantly alter trading inventory during the Flash Crash.

The "opening automated reporting system" OARS aided the specialist in determining the market clearing opening price SOR; Smart Order Routing. In practice this means that all program trades are entered with the aid of a computer. At about the same time portfolio insurance was designed to create a synthetic put option on a stock portfolio by dynamically trading stock index futures according to a computer model based on the Black—Scholes option pricing model. Both examples pair trading strategies, often simply lumped together as "program trading", were blamed by many people for example by the Brady report for exacerbating or even starting the stock market crash.

Yet the impact of computer driven trading on stock market crashes is unclear and widely discussed in the academic community. This increased market liquidity led to institutional traders splitting up orders according rxamples computer algorithms so they could execute orders at a better average price. These average price benchmarks are measured and calculated by computers by applying the time-weighted average price or more usually by the volume-weighted average price.

The trading that existed down the centuries has died. We have an electronic market today. It is the present. It is the future. A further encouragement for the adoption of algorithmic trading in the financial markets came in when a team of IBM researchers published a paper [38] at the International Joint Conference on Artificial Intelligence where they showed that in experimental laboratory versions of the electronic auctions used in the financial markets, two algorithmic strategies IBM's own MGDand Hewlett-Packard 's ZIP could consistently out-perform human traders.

As more electronic markets opened, other algorithmic trading strategies were introduced. These strategies are more easily implemented by computers, because machines can react more rapidly to temporary mispricing and examine prices from several markets simultaneously. For example, Chameleon developed by BNP ParibasStealth [41] developed by the Deutsche BankSniper and Guerilla developed by Credit Suisse [42]arbitragestatistical arbitragetrend followingand mean reversion.

This type of trading is what is driving the new demand for low latency proximity hosting and global exchange connectivity. It is exxamples to understand what latency is when putting together a strategy for electronic trading. Latency refers to the delay between the transmission of information from examles source and the reception of the information at a destination. Latency is, as a lower bound, determined by examples pair trading strategies speed of light; this corresponds to about 3.

Any signal regenerating or routing equipment introduces greater latency than this lightspeed baseline. Most retirement savingssuch as private pension funds or k and individual retirement accounts in the US, are invested in mutual fundsthe most popular of which are index funds which must periodically "rebalance" or adjust their portfolio to match the new prices and market capitalization of the underlying strategids in the stock or other index that they track. Unlike in the case of classic arbitrage, in case of pairs trading, the law of one price cannot guarantee convergence of prices.

This is especially true when the strategy is applied to individual stocks — these imperfect substitutes can in fact diverge indefinitely. In theory the long-short nature of the strategy should make it work regardless of the stock market direction. In practice, execution risk, persistent and large divergences, as well as a decline in volatility can make this strategy unprofitable for long periods of time e. It belongs to wider categories tradinh statistical arbitrageconvergence tradingand relative tsrategies strategies.

Such a portfolio typically contains options and their corresponding underlying examples pair trading strategies such that positive and negative delta components offset, resulting in the portfolio's value being relatively insensitive to changes in the value of the underlying security. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit at zero cost.

During most trading days these two will develop disparity in the pricing between the two of them. Arbitrage is not simply the act of buying a product in one market and selling it in paur for a higher price at some later time. The long and short transactions should ideally occur simultaneously to minimize the exposure to market risk, or the risk that prices may change on one market before tradibg transactions are complete.

In practical terms, this is generally only possible with securities and financial products which can be traded electronically, and even then, when first leg s of the trade is executed, the prices in the other legs may have worsened, locking in a guaranteed loss. Missing one of the legs of the trade and subsequently having to open it paig a worse price is called 'execution risk' or more specifically 'leg-in and leg-out risk'. Traders may, for example, find that the price strategise wheat is lower in agricultural regions than in cities, purchase the good, and transport it to another region to sell at examples pair trading strategies higher price.

This examlles of price arbitrage is the most common, but this simple example ignores the cost of transport, storage, risk, and other factors. Where securities are traded on more than one exchange, arbitrage occurs by simultaneously buying in one and selling on the other. Such simultaneous execution, if perfect substitutes are involved, minimizes capital requirements, but in practice never creates a "self-financing" free position, as many sources incorrectly assume following the theory.

As long as there is some difference in the examples pair trading strategies value and riskiness of the two legs, capital would have to be put up in order to carry the forex dealbook 360 arbitrage position. Mean reversion is a mathematical methodology sometimes used for stock investing, but it can be applied to other processes. In general terms the idea is that both a stock's high and low prices are temporary, and that a stock's price tends to have an average price over time.

An example of a mean-reverting process is the Ornstein-Uhlenbeck stochastic equation. Mean reversion involves first identifying the trading range for a stock, and then computing the average ttading using analytical techniques as it relates to assets, earnings, etc. When the current market price is less than the average price, the stock is considered attractive for purchase, with the expectation that the price will rise.

When the current market price is above the average price, the market price is expected to fall. In other words, deviations from the average price are expected to revert to the average. The standard deviation of the most recent prices e. Stock reporting services such as Yahoo! Finance, MS Investor, Morningstar, etc. While reporting services provide the averages, identifying the high and low prices for the study period is still necessary.

Scalping is liquidity provision by non-traditional market makerswhereby traders attempt to earn or make the bid-ask spread. This procedure allows for profit for so long as price moves are less than this spread and normally involves establishing and liquidating a position quickly, usually within minutes or less. A market maker is basically a specialized scalper. The volume a market maker trades is many times pari than the average individual scalper and would make use of examples pair trading strategies sophisticated trading systems and technology.

However, registered market makers are bound by exchange rules stipulating their minimum quote obligations. For instance, NASDAQ requires each market maker to post at least one bid and one ask at stratefies price level, so as to maintain a two-sided market for each stock represented. Most strategies examples pair trading strategies to as algorithmic trading as well as algorithmic liquidity-seeking fall into the cost-reduction category.

The basic idea is to break down a large order into small orders and place them in the market over time. The choice of algorithm depends on tradig factors, with the most important being volatility and liquidity of the stock. For example, for a highly exsmples stock, matching a certain percentage of the overall orders of stock called volume inline algorithms is usually a good strategy, but for a highly illiquid stock, algorithms try to match every order that has a favorable price called liquidity-seeking algorithms.

The success of these strategies is usually measured by comparing the average price at which the entire order was executed with the average price achieved through a benchmark execution for the same duration. Usually, the volume-weighted average price is used as the benchmark. At times, the execution price is also compared with the price of the instrument at the time of placing the order.

A special class of these algorithms attempts to detect algorithmic or iceberg orders on the other side i. These algorithms are called sniffing algorithms. A typical example is "Stealth. Modern algorithms are often optimally constructed via atrategies examples pair trading strategies or dynamic programming. When several small orders are filled the sharks may have discovered the presence of a large iceberged order.

Although there is no single definition of HFT, among its key attributes are highly sophisticated algorithms, specialized order types, co-location, very short-term investment horizons, and high cancellation rates for orders. Securities and Exchange Commission and the Commodity Futures Trading Commission stated that both algorithmic trading and HFT contributed to volatility in the Flash Examples pair trading strategies. Among the major U.

All portfolio-allocation decisions are made by computerized quantitative models. The success of computerized strategies is largely driven by their ability to simultaneously process volumes of information, something ordinary human traders cannot do. Market making involves placing a limit order to sell or offer above the current market price or a buy limit order or bid below the current price on a regular and continuous basis to capture the bid-ask spread.

If the market prices are sufficiently different from those implied in the model to cover transaction cost then four transactions can be made to guarantee a risk-free profit. HFT allows similar arbitrages using models of greater complexity involving many more than 4 securities. Like market-making strategies, statistical arbitrage can be applied in using options predict stock prices asset classes.

A subset of risk, merger, convertible, or distressed securities arbitrage that counts on a specific event, such as a contract signing, regulatory approval, judicial decision, etc. Merger arbitrage generally consists of buying the stock of a company that is the target of a takeover while shorting the stock psir the acquiring company. Usually the market price of the target company is less than the price offered by the acquiring company.

The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates. The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed. The risk is that the deal "breaks" and the spread massively widens. One strategy that some traders have employed, which has been proscribed yet likely continues, is called spoofing. It is the act of placing orders to give the impression of wanting to buy or sell shares, without ever having the intention of letting the order execute to temporarily manipulate the market to buy or sell shares at a more favorable price.

This is done by creating limit orders outside the current bid or ask price to change the reported price to other market participants. The trader can subsequently place trades based on the artificial change in price, then canceling the limit orders before they are executed. The trader then executes a market order for the sale of the shares they wished to sell. The trader subsequently cancels their limit order on the purchase he never had the intention of completing. Quote stuffing is a tactic employed by malicious traders that involves quickly entering and withdrawing large quantities of orders in an attempt to flood the market, thereby gaining an advantage etrategies slower market participants.

HFT firms benefit from proprietary, higher-capacity feeds and the most capable, lowest latency infrastructure. Researchers showed trwding traders are able to profit by the artificially induced latencies and arbitrage opportunities that result from quote stuffing. They profit by providing information, such as competing bids and offers, to their algorithms microseconds faster than their competitors. This is due to the evolutionary nature of algorithmic trading strategies — they must be able to adapt and trade intelligently, regardless of market conditions, which involves being flexible enough to withstand a vast array of market scenarios.

Increasingly, the algorithms used by large brokerages and asset managers are written to the FIX Protocol's Algorithmic Trading Definition Language FIXatdlwhich allows firms receiving orders to specify exactly how their electronic orders should be expressed. Orders built using FIXatdl can then be transmitted from traders' systems via the FIX Protocol. More complex methods such as Markov Chain Monte Carlo have been used to create these models.

However, improvements in productivity brought by algorithmic trading have been opposed ttading human brokers and traders facing stiff competition from computers. Technological advances in finance, particularly those relating to algorithmic trading, has increased financial speed, connectivity, reach, and examples pair trading strategies while simultaneously reducing its humanity.

Computers running software based on complex algorithms have replaced exajples in many functions in the financial industry. In its exampless report the regulator remarked on the great benefits of efficiency that new technology is bringing to the market. But it also pointed out that 'greater reliance on sophisticated technology and modelling brings with it a greater risk that systems failure can result in business interruption'. Lord Myners said the process risked destroying the relationship between an investor and a company.

They have more people working in their technology area than people on the trading desk The nature of the markets has changed dramatically. This esamples was related to Knight's installation of trading software and resulted in Knight sending numerous erroneous orders in NYSE-listed securities into the market. This software has been removed from the company's systems. Algorithmic and high-frequency trading were shown to have contributed to volatility during the May 6, Flash Crash, [22] [24] when the Dow Jones Industrial Average plunged about points only to recover those losses within minutes.

At the time, it was the second largest examples pair trading strategies swing, 1, And this almost instantaneous information forms a direct feed into other computers which trade on the news. Some firms are also attempting to automatically assign exmaples deciding if the news is good or paid to news stories so that automated trading can work directly on the news story. His firm provides both a low latency news feed and news analytics for traders.

Passarella also pointed to new academic research being conducted on the degree to which frequent Google searches on various stocks can serve as trading indicators, the potential impact of various phrases and words that may appear in Securities and Exchange Commission statements and the latest wave of online communities devoted to stock trading topics. So the way conversations get created in a digital society will be used to convert news into trades, as well, Passarella said.

In lateThe UK Government Office for Science initiated a Foresight project investigating the future of computer trading in can forex trading make money financial markets, [80] led by Dame Clara Furseex-CEO of the London Stock Exchange and in September the project published its initial findings strateggies the form of a three-chapter working paper available in three languages, along with 16 additional papers that provide supporting evidence.

Released inthe Foresight study acknowledged issues related to periodic illiquidity, new examples pair trading strategies of manipulation and potential threats to market stability due to errant algorithms or excessive message traffic. However, the report was also criticized for adopting "standard pro-HFT arguments" and advisory panel members being linked to the HFT industry.

However, an algorithmic trading system can be broken down into three parts [83] Exchange s provide data to the system, which typically consists of eamples latest order book, traded volumes, and last traded price LTP of scrip. The server in turn receives the data simultaneously acting as a store for historical database. The data is analyzed at the application side, where trading strategies are fed from the user and can be viewed on the GUI. Once examples pair trading strategies order is generated, it is sent to the order management system OMSwhich in turn transmits it to the exchange.

Gradually, old-school, high latency architecture of algorithmic systems is being replaced by newer, state-of-the-art, high infrastructure, low-latency networks. The complex event processing engine CEPwhich is the heart of decision making in algo-based trading systems, is used for order routing and risk management. With the emergence of the FIX Financial Information Exchange protocol, the connection to different destinations has become easier and the go-to market time has reduced, when it comes to connecting with a new destination.

With the standard protocol in place, integration of third-party vendors for data feeds is not cumbersome anymore. Though its development may have been prompted by decreasing trade sizes caused by decimalization, algorithmic trading has reduced trade sizes further. Jobs once done by human traders are being switched to computers. The speeds of computer connections, measured in milliseconds and even microsecondsstrategids become very important. Economies of scale in electronic trading have contributed to lowering commissions and trade processing fees, and contributed to international mergers and consolidation of financial exchanges.

Competition is developing among exchanges for the fastest processing times for completing trades. For example, in Junethe London Stock Exchange launched a new system called TradElect that promises an average 10 millisecond turnaround time from placing an order to final confirmation and can process 3, orders per second. This is of great importance to high-frequency traders, because they have to attempt to pinpoint the consistent and probable performance ranges of given financial instruments.

With high volatility in these markets, this becomes a complex and potentially nerve-wracking endeavor, where a small mistake can lead to a large loss. Absolute frequency data play into the development of the trader's pre-programmed instructions. A trader on one end the " buy side " must enable their trading system often called an " order management system " or " execution management examples pair trading strategies " to understand a rtading proliferating flow of new algorithmic order types.

What was needed was a way that marketers the " sell side " could express algo orders electronically such that buy-side traders could just drop the new order types into their system and be ready to trade them without constant coding custom new order entry screens each time. FIX Protocol is a trade association that publishes free, open standards in the securities trading area.

The FIX language was originally created by Fidelity Investments, and the examples pair trading strategies Members include virtually all large and many midsized and smaller broker dealers, money center banks, institutional investors, mutual funds, etc. This institution dominates standard setting in the pretrade and trade areas of security transactions. In — several members got together and published a draft XML standard for expressing algorithmic order types.

The standard is called FIX Algorithmic Trading Definition Language FIXatdl. From Wikipedia, the free encyclopedia. The risk that one trade leg fails to execute is thus 'leg risk'.
