Basics of High Frequency Trading

Nanex’s High Frequency Trading Model (Sped Up)

Nanex released a video showing the results of half a second of worldwide high frequency trading with Johnson and Johnson stock. I simply sped up the footage to get a better feel of what it looked like. Blow Your Mind.

Wild High Frequency Trading Algo Destroys eMini Futures

One of the scariest high frequency trading algos ran in the electronic S&P 500 futures (eMini) contract on January 14, 2008 starting at 2:01:11Eastern. During its 7 second reign, there were over 7,000 trades (52,000 contracts), and the price eventually oscillated within milliseconds, the equivalent of about 400 points in the Dow Jones Industrial Average!


HFT trading ideally must have the lowest possible info latency (time delays) and the maximum potential automation level. So participants prefer to trade in markets with high levels of integration and automation capacities in their trading platforms. These include NYSE NASDAQ, Direct Edge and BATS.
HFT is controlled by proprietary trading firms and spans across multiple securities, including equities, derivatives, index funds and ETFs, currencies and fixed income instruments.For HFT, participants want the following infrastructure in place:
– High speed computers, which need costly and regular hardware upgrades;
– Co-location.
– Real time data feeds, which must avert even the delay which could affect profits; and of a microsecond
– Computer algorithms, which are the heart of HFT and AT.

Benefits of HFT
– HFT is beneficial to traders, but does it help the total marketplace? Some market that is overall gains that HFT assistants cite contain:
– Bid-ask spreads have reduced due to HFT trading, making markets more efficient. Empiric evidence contains that after Canadian authorities in April 2012 imposed fees that deterred HFT, studies indicated that “the bid-ask spread rose by 9%,” possibly due to diminishing HFT trades. And thus facilitates the effects of market fragmentation.

– HFT assists in the price discovery and price formation process, as it is centered on a high number of orders (see related: How The Retail Investor Profits From High Frequency Trading.)

Basics of Machine Learning in Algorithmic Trading

Algorithmic Game Theory and Practice, Michael Kearns, University of Pennsylvania,

Traditional financial markets have undergone rapid technological change due to increased automation and the introduction of new mechanisms. Such changes have brought with them challenging new problems in algorithmic trading, many of which invite a machine learning approach. I will briefly survey several algorithmic trading problems, focusing on their novel ML and strategic aspects, including limiting market impact, dealing with censored data, and incorporating risk considerations.

 

 

Machine learning for algorithmic trading w/ Bert Mouler

Harnessing the power of machine learning for money making algo strategies with Bert Mouler

Practical Tips For Algorithmic Trading (Using Machine Learning)
Evgeny Mozgunov from Caltech won an algorithmic trading competition hosted by Quantiacs. Jenia used machine learning tools to write his trading algorithm that now trades an initial $1M investment. He is talking about his approach and his main learnings. Jenia’s algorithm currently has a live Sharpe Ratio of 2.66.
 
Machine Learning and Pattern Recognition for Algorithmic Forex and Stock Trading
This is a whole course (20 videos) on machine learning and algorithmic trading. In this series, you will be taught how to apply machine learning and pattern recognition principles to the field of stocks and forex. This is especially useful for people interested in quantitative analysis and algo trading. Even if you are not, the series will still be of great use to anyone interested in learning about machine learning and automatic pattern recognition, through a hands-on tutorial series.
 

The following frontier of the technological arms race in finance is artificial intelligence. Improvements in AI research have triggered massive curiosity about the sector, where some consider a a trading, learning and thinking computer will make even today’s superfast, ultra-complicated investment algorithms appear archaic — and potentially leave human fund managers redundant. Could the next generation’s Buffett be a super-algo?

Some of the world’s largest cash managers are betting on it. AI investing may sound as, although fantastical sci-fi writer William Gibson said The future is already here, it’s simply not evenly dispersed.” Bridgewater, the world’s biggest hedge fund group, poached the head of IBM’s artificial intelligence unit Watson in 2012, and Two Sigma and last year BlackRock, another rapidly growing hedge fund that uses quantitative models, hired two former top Google engineers. Headhunters say computer scientists are now the hottest property in finance.

The quantitative investment world plays down the prospect of machines arguing that human genius still plays an important part, pointing out that the prospect of artificial intelligence that is complete is still distant, and supplanting human fund managers. But the confident swagger of the cash management nerds is unmistakable. There are quasi-AI trading strategies working their magic and the future belongs to them, they predict.

Artificial intelligence and video that is financePlay
The time will come that no human investment manager will manage to defeat the computer.” Or, as Agent Smith put it succinctly in The Matrix: “Never send a human to do a machine’s occupation.”

Yin Luo first learned to code after an used Apple II computer was brought back to China by his dad from a business trip to West Germany in 1985, when he was 11. But there were no games to purchase his home town in Heilongjiang province, in Yichun, so he made a crude variation of Tanks, where the player shoots down randomly created aeroplanes and taught himself to program.
It was arduous work. The computer’s lack of memory meant it crashed the program coding grew not too simple. He’d no floppy discs, so he learnt how to save the info on cassette tapes. “I just really needed something to play with,” Mr Luo recalls.

But the expertise paid off. Now, he is part of a growing tribe of brainiacs on Wall Street investigating the bleeding edge of computer science.

A network of 20 Linux servers is needed to run the hyper-sensible “ adaptive style turning” that was linear model, which is founded on a “machine learning” algorithm.

Machine learning is a branch of AI a diffuse term that is certainly frequently misused or misunderstood. While many people comprehend AI to mean sentient computers like the archvillains SkyNet in the Terminator films or HAL 9000 in 2001: A Space Odyssey, in practice everyday tools including Google’s language translation service, Netflix’s film recommendation engine or Apple’s Siri virtual assistant install basic forms of AI.

Quants have long used increasingly powerful computers to crunch numbers and uncover statistical signs of money-making opportunities, but machine learning goes a step further.

It can learn the difference between apples and bananas and sort out them, or perhaps instruct a computer how to play and quickly master a game like Super Mario from scratch. Machine learning can also be unleashed on “unstructured data”, such as for example jumbled amounts but also pictures and videos which can be typically not easy for a computer to comprehend.

More powerful computers mean that it are now able to be applied to financial markets, although the technique is old. “It’s a very bright area,” Mr Luo says. “Artificial intelligence is able to help you find designs an individual would never see. That may give you an enormous advantage.”

But that is not the only advantage of machine learning.

When marketplaces undergo what industry participants call a regime change that is “ ” and trusted strategies no more use, one of the classic challenges for quants is that their models can often prove worthless — or worse. Algorithmic trading strategies that print cash one day can blow the next up.

A machine learning algorithm adjusting to what works in markets that day, will autonomously develop and search for new patterns.
That means they can be used by asset managers as something to develop trade and strategies by itself, or perhaps to enhance their investment process, maybe by screening for patterns undetectable by people.

For Nick Granger, a fund manager at Man AHL, a quant hedge fund, that is the advantage that is critical. “You see it creating intuitive trading strategies in the bottom up, changing styles according to what works,” he says. “ We have been using machine learning for the past few years and have an interest in investing it in more.”

Nonetheless, machine learning has pitfalls. One of the largest challenges for quants is a phenomenon called “overfitting”, when an algorithm that is coded or exceedingly complicated finds false signals or specious correlations in the noise of data. For instance, a blog called “Spurious Correlations” notes that margarine consumption is linked to Nick Cage pictures to swimming pool drownings, and divorce rates in Maine.

When confronted by actual markets even if your model functions well in testing it can fail. Also, new data can be changed by the trading algorithm, says Osman Ali, a quant at Goldman Sachs’ asset management arm. “ you’re not affecting the weather, but if you deal marketplaces they are being affected by you If you crunch weather data.”

Nor can the most complex AI think as creatively as an individual, especially in a crisis. Brad Betts, a former Nasa computer scientist now working at BlackRock’s “ active equity” arm that is scientific, emphasizes the 2009 emergency plane landing on the Hudson river by Chesley Sullenberger of when machine is trumped by man as an example.

Truly, some quants remain sceptical that machine learning — AI or more broadly — is a holy grail for investment. Many see it just as a fresh, sophisticated gizmo to supplement their present toolkit, but others claim it truly is mainly a case of intelligent marketing rather than something genuinely ground-breaking.

They do’t constantly work, although “People are always desperate to find new ways to earn money in financial markets. He points out the human brain is uniquely adept at pattern recognition, “whether it really is love, a triangle or a face. Investment management is totally amenable to being addressed by computers designed to see patterns, but I’m not going to rush to use the latest hot algo to do so.”

 

Basics of algorithmic trading

Algo-trading provides these advantages:

 
– Trades executed at the best possible prices
– Immediate and accurate trade arrangement positioning (thereby high likelihood of performance at desired amounts)
– Trades timed right and forthwith, to avert significant cost changes
– Reduced transaction costs (see the execution shortfall example below)
– Coincident automated tests on multiple marketplace states
– Decreased risk of manual errors in placing the trades
– Backtest the algorithm, depending on available historical and real time data
– Reduced chance of errors by human traders based on variables that are mental and emotional
  

Algorithmic Trading Strategies

Any strategy for algorithmic trading requires an identified chance which will be rewarding when it comes to improved gains or cost reduction. The following are common trading strategies used in algo trading:
 
Trend Following Strategies
The most common algorithmic trading strategies follow fads in moving station breakouts, averages, price level moves and technical indicators that are related. These are most straightforward and the easiest strategies to execute through algorithmic trading because these strategies don’t involve making any predictions or price outlooks. Trades are commenced depending on the incidence of desired tendencies, which are easy and straightforward without getting into the complexity of predictive analysis to implement. The aforementioned example of 200 and 50 day moving average is a popular trend following strategy.
 
Arbitrage Opportunities
Purchasing a dual listed stock at a lower cost in one market and simultaneously selling it at an increased price in another marketplace offers the price differential as risk free gain or arbitrage. The same operation can be duplicated for stocks versus futures instruments, as price differentials do exists from time to time. Implementing an algorithm to identify such price differentials and placing the orders enables lucrative opportunities in efficient manner.
 
Index Fund Rebalancing
Index funds have defined periods of rebalancing to bring their holdings to level with their respective benchmark indices. This creates opportunities that are lucrative for algorithmic dealers, who capitalize on anticipated trades that offer 20-80 basis points gains depending upon how many stocks in the index fund, only prior to index fund rebalancing. Such trades are initiated via algorithmic trading systems for best costs and timely performance.
 
Mathematical Model Based Strategies
A lot of proven mathematical models, like the delta-neutral trading strategy, which enable trading on combination of its underlying security and alternatives, where trades are placed to cancel positive and negative deltas so that the portfolio delta is kept at zero.
 
Trading Range (Mean Reversion)
Mean reversion strategy is dependant on the idea the low and high costs of an asset are a temporary phenomenon that revert to their mean value periodically. Identifying and explaining a price range and implementing algorithm based on that allows trades to be put automatically when cost of advantage breaks in and out of its defined range.
 
Percent of Volume (POV)
Until the commerce order is fully filled, this algorithm continues sending partial orders, based on the defined contribution ratio and according to the volume traded in the markets.
 
Implementation Shortfall
The implementation shortfall strategy aims at minimizing the performance cost of an order by trading off the real time marketplace, thereby saving on the cost of the order and benefiting in the opportunity cost of delayed performance. The participation speed that is targeted will be increased by the strategy when the stock price moves positively and decrease it when the stock price moves adversely.
 
Beyond the Usual Trading Algorithms
There are a few special classes of algorithms that try to identify “happenings” on one other side. These “sniffing algorithms,” used, for instance, by a sell side market maker have the inbuilt intelligence to identify the existence of any algorithms on the buy side of a large order. Such detection through algorithms will help the market maker identify large order opportunities and enable him to gain by filling the orders at a cost that is higher. This is occasionally identified as high-tech front-running. (For more on high frequency trading and deceptive practices, see: If You Buy Stocks Online, You Are Involved in HFTs.)
 
Time Weighted Average Price (TWAP)
Time weighted average cost strategy breaks up a large order and releases determined smaller balls of the order to the marketplace using equally split time slots between a start and ending time. The intention is to carry out the order close to the average cost between the end and start times, thereby minimizing market impact.
 
Volume Weighted Average Price (VWAP)
Quantity weighted average cost strategy breaks up a large order and releases determined smaller balls of the order to the market using stock particular historic volume profiles. The aim would be to carry out the order close to the Volume Weighted Average Price (VWAP), therefore gaining on average cost.

Books on Algorithmic Trading

Algorithmic trading is usually perceived as a complicated area for beginners to get to grips with. It covers a broad range of subjects, with certain aspects requiring a substantial amount of adulthood that is mathematical and statistical. Hence it can be incredibly off-putting for the uninitiated. While the details can be learned in an
iterative, on-going manner, in reality, the overall concepts are clear-cut to understand.
The beauty of algorithmic trading is that there is no need to test ones knowledge on real capital out, as highly realistic marketplace simulators are provided by many brokerages. They provide an environment to cultivate a deep level of understanding, with zero capital risk, while there are specific caveats associated with such systems.
One post cannot hope to cover the diversity of the subject, although I ‘ve already composed a beginner’s guide to quantitative trading. Consequently I Have decided to advocate my favourite entry-level quant trading publications in this article.
The first task would be to get a solid summary of the subject. I ‘ve found it be much easier to avoid substantial mathematical discussions until the basics are covered and understood. The finest books I have found for this objective are as follows

The Evaluation and Optimization of Trading Strategies  by Robert Pardo
 
A newly expanded and updated edition of the trading vintage, Design, Testing, and Marketing of Trading Systems Trading systems specialist Robert Pardo is back, and in “The Examination and Optimization of Trading Strategies,” a totally revised and updated version of his classic text “Style, Testing, and Optimization of Trading Systems,” he reveals how he’s improved the programming and testing of trading systems using a prosperous battery of their own time-established methods. Pardo provides information to visitors, in the style of feasible trading ways of measuring concerns like profit and risk. Published in a straightforward and accessible design, this detailed guide presents traders with an approach examine their trading strategy no matter what type they’re currently applying and to produce -stochastics, moving data patterns, averages, RSI, or breakout methods. Whether a broker is currently seeking to improve their revenue or perhaps getting started in screening, ” Trading Strategies’ Evaluation and Marketing ” gives useful education and qualified advice to the development, analysis, and application of winning physical trading systems.

Algorithmic Trading & DMA by Barry Johnson
We recommend this book for its simple literary instances of trading strategies coupled with examples and figures, which allow the reader to clearly understand the function of trading scenarios. Johnson goes to great lengths to clarify the variables determining prices, liquidity, market impact and unpredictability. He makes accessible to his readers wide-ranging references and outlines closing each chapter, which make a great addition to the publication out. Called a “model of clarity” by readers, DMA and Algorithmic Trading emerges at the perfect time to unite lay person with complicated process.
The phrase ‘algorithmic trading’, in the financial sector, usually refers to the execution algorithms used by banks and brokerages to perform trades that are efficient. I ‘m using the term to cover not only those aspects of trading, but also quantitative or systematic trading. Barry Johnson, who’s a quantitative software developer at an investment bank is primarily about the former, writing this book. Does this mean it is of no use to the retail quant? Possessing a more profound comprehension of how exchanges work and “market microstructure” can assist exceptionally the profitability of retail strategies. It’s worth picking up despite it being a heavy tome.

The Science of Algorithmic Trading and Portfolio Management  by Robert Kissell
Its emphasis on algorithmic trading processes and current trading models sets this book apart from others. As the first writer to discuss algorithmic trading across the various asset classes, assemble, and Robert Kissell provides vital insights into methods to develop, analyze trading algorithms. He summarizes market structure, the formation of prices, and how distinct participants socialize with one another, including bluffing, supposing, and betting. He shows readers the inherent details and mathematics needed to develop, assemble, and test customized algorithms, providing them with advanced modeling techniques to enhance profitability through risk management techniques that are appropriate and algorithmic trading. The accompanying web site includes examples, data sets underlying activities in the novel, and substantial projects. Readers learn the best way to value market impact models and assess functionality across algorithms, dealers, and agents, as well as acquiring the skill to execute electronic trading systems.
Prepares readers assess performance across algorithms, traders, and brokers and to evaluate market impact models.
Helps readers design systems to handle dim pool uncertainty and algorithmic danger.

You concentrate your attention on the market, absorb the effects in your cash, and promptly resolve problems that impact profits by really making trades.
Algorithmic trading began as a “ridiculous” concept in the 1970s, subsequently became an “unfair advantage” as it evolved into the lynchpin of a successful trading strategy. This book gives you the backdrop you need to effectively reap the advantages of this significant trading process. Navigate confusing markets Find the right trades and make them Develop a successful algo trading system Turn insights into strategies that are lucrative
Algorithmic trading strategies are everywhere, but they’re not all equally valuable. It is far too easy to fall for something that worked previously, but with little expectation of working later on. “A Guide to Creating a Successful Algorithmic Trading Strategy” shows you how to choose the best, leave the remainder, and make more cash from your trades.

Quantitative Trading by Ernest Chan
Dr. Chan provides a great overview of the procedure of setting up a “retail” quantitative trading procedure, using MatLab or Excel. He makes the subject highly approachable and gives the belief that “anyone can do it”. Although there are tons of details that are skipped over (mainly for brevity), the publication is a fantastic introduction to how algorithmic trading works. He discusses alpha generation (“the trading model”), risk management, automated execution systems and certain strategies (particularly impetus and mean reversion). This publication is the place to begin.

Building Winning Algorithmic Trading Systems: A Trader’s Journey From Data Mining to Monte Carlo Simulation to Live Trading by Kevin Davey
In Constructing Algorithmic Trading Systems: A Trader’s Trip From Data-Mining to Monte Carlo Simulation award-winning, to Reside Instruction trader Kevin Davey gives his tricks for developing trading systems that create multiple-digit earnings. With both display and clarification, Davey manuals you step-by-step through the complete means of testing techniques, placing access and exit factors, verifying and making an idea, and employing them in live trading. You’ll find real policies for increasing or decreasing allowance to your system, for when to abandon one and rules. The companion site incorporates Davey Montecarlo simulator and other tools that will enable you test and to automate your own trading ideas.
A purely discretionary way of trading usually reduces over the long term. With data and market knowledge readily available, dealers are increasingly opting to hire algorithmic trading system—enough or an automated that algorithmic positions now account for the bulk of stock trading volume. Building Algorithmic Trading Systems teaches you just how to acquire your own programs with the attention toward market variations as well as also the top algorithm’s impermanence.
Learn the methods that made double-digit dividends in the World Cup Trading Tournament Develop an algorithmic approach for almost any trading notion using off-the-shelf software or common programs Check your system using traditional and current market Data-Mine marketplace information for mathematical habits that may form the idea of the new system
Market styles change, and thus do technique outcomes. Prior performance is not a guarantee of future achievement, therefore alter methods that are recognized in reaction to changing statistical habits and the key would be to frequently build new techniques. For specific professionals seeking the next revolution, Building Algorithmic Trading Systems delivers expert useful and assistance assistance.

Inside the Black Box by Rishi K. Narang 
In this book Dr. Narang explains in detail how a professional quantitative hedge fund functions. It’s pitched at a knowledgeable investor who’s contemplating whether to invest in such a “black box”. Despite the seeming irrelevance to a retail dealer, the book really includes a wealth of information on how a “suitable” quant trading strategy should be carried out. For example, the significance of transaction costs and risk management are summarized, with thoughts on where to look for further info. Many retail algo dealers could do well to pick this up and see the ‘professionals’ carry out their trading.

Trading and Exchanges by Larry Harris
This publication concentrates on market microstructure, which I personally believe is an essential place to learn about, even at the beginning phases of quant trading. Marketplace microstructure is the “science” of how market participants socialize and the dynamics that appear in the order book. It’s closely related to what actually occurs when a trade is set and how exchanges function. This book is less about trading strategies such, but more about matters to be aware of when designing execution systems. Many professionals in the quant finance space regard this as a superb novel and I also highly recommend it.

Constructing Winning Algorithmic Trading Systems by Kevin Davey
Written by a well-qualified, seasoned trader, Davey does more than give rules and examples, although they are in there also. In his novel, Davey reveals his personal strategy that won him the World Cup Championship of Futures Trading. The novel is un-presumptuous and engaging. It comprises real-world guidance and readily understood direction. From an author who actually makes his living at what he is trying to sell here, this book is inspiring and dynamic. Davey understands how exactly to talk the talk, but he goes a step further and reveals his audience which he can just as easily walk the walk- and he does. Readers’ reviews say the novel is worth every penny it costs. Most refer to it as an investment or a down payment of sales to come.

Algorithmic Trading: Winning Strategies and their Reasoning by Ernie Chan
This second book on algorithmic trading by Chan delves. While his audience fairly well received Quantitative Training, its primary focal point was never about strategy in trading. Reader opinions brought about the writing of this second book, which really brings home the practical and useful strategy that brings results in the market. This more practical guide includes wide-ranging examples of strategies that unique insight that can only come from someone who has spent a whole lot of time trading has been executed, together with by Chan himself. An interesting read, Algorithmic Trading reveals many different strategies including-
To choose the automated execution platform that is right
* Simple techniques for trading mean-reverting portfolios
* Mean-reverting strategies for stocks
* Newer momentum strategies
Chan’s book takes into consideration that applications and mathematics are the basic languages of algorithmic trading- and does’t deviate quite far from that comprehension at any time along the way.

 


 

The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It  by Scott Patterson
In March of 2006, the world’s richest men sipped champagne in an opulent Ny hotel. They were getting ready to compete in a poker tournament with million-money stakes, but those figures meant nothing to them. These were accustomed to risking billions.
In the card table that night was Peter Muller, an eccentric, whip-smart whizkid now handled a wonderfully successful hedge fund named PDT…when he wasn’t enjoying his keyboard for day commuters on the Ny subway and who’d examined theoretical math at Princeton. Was Ken Griffin, who made profit one of many bear areas of all time and as an trading convertible securities out of his Harvard dorm room had outsmarted the Wall Street pros. Now he was the difficult-as-nails mind of Citadel Investment Group, one of the most effective cash machines on the planet. There too were Cliff Asness, the sharp tongued, mercurial president of the hedge fund AQR, a man as well-known for his pc-smashing rages in terms of his elegance, and Boaz Weinstein, chess life-master and king of the credit default exchange, who while juggling $30 million value of positions for Deutsche Bank identified occasion for frequent trips to Vegas together with the famed MIT cardcounting team.
On that night in 2006, these four guys as well as their cohorts were Wall Street’s brand new leaders. Muller, Griffin, Asness, and Weinstein were among the best and brightest the quants, of a new type. Within the preceding 20 years, this variety of math whiz –technocrats who produce billions not with gut calls or simple research but with formulas and high speed computers– had usurped the testosterone-fueled, kill-or-be-killed risktakers who’d always been the alpha men the world’s biggest casino. The quants believed a wild, indecipherable-to-pure-mortals drink of differential calculus, quantum physics, and advanced geometry used the key to enjoying riches in the financial markets. Plus they helped develop a digitized cash-trading unit that may shift millions around the world with the press of the mouse.
Few understood that night, however, that in making this machine that was unprecedented, guys like Muller, Griffin, Asness and Weinstein had sowed the vegetables for history’s greatest economic disaster.
Drawing on unprecedented access to these four-number-bashing titans, The Quants tells the interior account of the things they imagined and believed in the days and months once they helplessly saw much of their networth vaporize – and wondered so how their mindbending formulas and genius-level IQ’s had directed them-so wrong, so fast. Had their decades of accomplishment been stupid luck, fool’s platinum, a great work that may come to an end on any given time? What if The Facts they sought — the secret of the areas knowable? Worse, imagine if there wasn’t any Fact?
Within The Quants, Scott Patterson tells the story not only of the guys, but of Jim Simons, the reclusive founder of the very most profitable hedge fund in history; Aaron Brown, the quant who used his math skills to embarrass Wall Street’s old guard at their logo sport of Liar’s Poker, and years later identified herself with a front-row seat for the rapid introduction of mortgage-backed securities; and gadflies and dissenters for example Paul Wilmott, Nassim Taleb, and Benoit Mandelbrot.
Using the immediacy of today’s NASDAQ close as well as the tragedy’s timeless energy, The Quants are at once a masterpiece of informative literature, a gripping history of goal and hubris…and an ominous warning about Wall Street’s potential.

Definitely give you a better knowledge and while using reputable books like these can enhance the trading experience and insight into the commerce world, it’s always needed to keep in mind that no one formula is foolproof; nothing is a guarantee of success. With increased hands on experience and great guidance from the pros, combined with devotion and hard work, it is possible to build a portfolio in trading. These publications will undoubtedly give you the greatest possible advantage.

Some random thoughts on algorithmic trading

The future is most algorithmic. This really is a potential scenario for disintermediation. The human trader’s attention span, processing and endurance only cannot match the functionality demands of marketplace action and intricacy and the volatile developments in trade volume which is increasing exponentially. The Tier 1 firms will increasingly have to rely on algorithmic trading and will shrink their trader headcount in the act, as the avalanche of information to be processed and responded to goes from gigabytes to terabytes. The substantial investment in algorithmic trading will give you – ‘intelligent’ algorithms which make their ‘own’ decisions to optimize trades to many surprises. The area of artificial intelligence is not adequately explored and will finally yield some important advances in the near future. Predictive algorithms will emerge with a hit rate that is reasonable and the predictive horizon will stretch farther into the future. As Artificial Intelligence (AI) and Artificial Neural Networks and Genetic Networks develop to reach critical mass with the increased ability of predictive estimators we envisage a shoal of rapacious ALPHA ALGOS will be released into the algorithmic trading space. In our miniscule way we’re the vanguard supplying the first dose of ALPHA ALGOS for the individual trader. We will be studying P1: OTA/XYZ P2: ABC c10 JWBK496/ Leshik 2011 8:7 Printer Name: Yet to Come 38 Introduction to Trading Neural Networks to expand the trading toolbox of the individual dealer. Or even counseling on the choice of the Head Dealer. In the long run it seems like it will wind up as a conflict between supercomputers, with the person trader almost entirely out of the actual trading picture – but that may be a while. There may be enough time to turn or flatten out the tendency a bit. Ray Kurzweil’s vision of the singularity’ that is ‘ does, nevertheless, loom on the horizon. This type of supercomputer scenario is filled with potential disasters of most kinds – functional, regulatory and human. It’d not be frighteningly difficult to subvert this type of powerful system as the architectural complexity would be beyond the intellectual grasp of any single individual, regardless of how talented. The system could then succumb to your disciplined team approach. It’d be a fantastic accomplishment for the marketplaces if more and more people would enter the fray and take liability for trading their own hard earned funds. To them it is their lifeblood. To the professional dealers it’s a well paid job. We would like to give to this hoped for tendency by supplying applications of algorithmic trading, the requisite concepts and background information. Leveling the playing field from tipping over and keeping it, is a gigantic job, but in our opinion, a rewarding one.
To Err Is Human. Blunders are made by Individual. Thats why we make machines to overcome our errors.
Algorithmic trading of securities is now a staple of modern approaches to monetary investment.
Artificial Intelligence plays a massive part in our lives and will play a larger part.
Algo-trading has proven to be quite precise and can be a rewarding instrument for investors in determining profitable stock picks.
I Know First’s algorithm has a success rate that speaks for itself.
There’s tons of advantages of algorithmic trading : –
–Enhanced Order Entrance Rate
–Minimize Emotions
–Skill to Backtest
–Preserve Discipline
–Attain Consistency
Disadvantages of Automated Trading
–Mechanical failures
–Over-optimization
–Monitoring
Judgment on algorithmic trading – although appealing for a number of factors, automated trading systems should not be considered a substitute for carefully carried out trading.
Given the evolution of the financial markets, many analysts and researchers today believe that algorithms that are only are the future of trading. But there are reasons. Within an attempt to estimate the future of algorithmic trading, your opinion is wanted by the Algorithmic Traders Association.
Market arrangement, and the markets, are always changing. Already largely technology dependent, the financial markets are becoming electronic, and researchers and quite several analysts now believe that algorithms that are only are the future of markets. Nevertheless, upon a consideration that is bit deeper, this statement doesn’t appear to be so obvious, and we can identify two important reasons for that.
If we take a look at the history of markets, we can see that progress within their construction and infrastructure never supplied any marketplace participants with a long term edge. Really, any such improvements may provide an advantage just until it becomes common. During the era of early computerization of markets, nearly anyone with a computer had a major advantage over those that traded within an old fashioned manner; when computers became part of regular life yet, this edge was partially levelled. One of the latest examples – latency arbitrage can be mentioned by us, high frequency trading and other similar techniques – that edge completely depends merely on the advantage in technology.
While just several market participants were not physically unable to trade on the sub-millisecond level, it indeed provided a fantastic border to them, but with more extensive distribution of this technology, this border is gradually reducing. Many former high frequency dealers turn to lower-frequency options, introducing elements of directional trading. The same issues now are associated with algorithms aiming to find the best performance, be they liquidity seekers, iceberg or others. Thus we can assume that algorithmic trading in general may provide an edge just for a certain limited time, finally asking for better trading decisions that are human.
Another reason to consider that the future may be not as algorithmic now as you can envision is the perpetual changes in regulations. All of us remember what happened in 2013 and specially 2014 when new requirements aiming for better transparency resulted in unprecedented low volatility and afterwards caused lots of trading algorithms to fail (see my previous article on the subject, “The Great Comeback of Unpredictability-Based Alpha-Generating Strategies”).
Lately I was encouraged by Algorithmic Traders Association to head their educational and research section, and as part of the project we decided to arrange a survey asking for opinions of various professionals more or less related to trading in general and algorithmic or systematic trading in particular: developers, risk managers, prop traders, institutional dealers, retail dealers. We consider that the investigation of the survey’s results may show the authentic public opinion, and we all know that in many cases public opinion is what determines the real future.
Please take part in this brief survey, which can be found here. We are going to release the results on our web site, but also here, so you may have easy access to it the moment it’s complete. We’re really intrigued to see the actual distribution of votes, and hope that it will not be uninteresting to you as well.
Societal benefits of HFT and Algo trading – regulators should embrace them
The enormous increase in fiscal trading volumes in the past number of decades continues to be made possible just with the usage of technology. Technology has helped in
– automating the dissemination of market data and other pertinent information by trading participants and exchanges
– capturing and consolidation of market data from various exchanges and other sources of related information
– making intricate calculations on data that is historical and live, leading to trade conclusions
– trading and handling danger
– lowering cost and the latency of trading
– various post-commerce procedures
Technology is heavily and usually economically used by brokerages (supplying various retail and institutional investors access to financial markets), high frequency traders (who trade in tremendous volumes aggregating little profits in as many trades as possible, this usually contains arbitrageurs and market makers), quant algo dealers (who use quantitative models to forecast the future prices etc.), exchanges (who are the liquidity aggregators forming marketplaces), and various other market participants. Each stake holder mentioned above has an important function in the orderly function of the financial markets. Complete Risk Management is the leading demand in handling these fiscal algorithmic trading companies.
There has been a major backlash against the fiscal firms (primarily the ones driven by technology including HFT and algorithmic trading companies) specially since the Flash Crash – US marketplaces in 2010, Knight Capital posting a major loss due to algo technology glitch in 2012, and various other occasions. According to some estimates, over 60% of US equity trading and over 30% of UK equity trading can be accounted to HFT firms. Politicians and regulators across the world have attempted to control high frequency trading and the algo in particular by coming up with some pretty interesting suggestions and arguments,
– European regulator needing Half-second delay before performance of a trade or cancelling an order in a bid to check motivators of trading fast.
It’s like introducing a speed breaker on a high way. Individuals will drive very fast up to the breaker, and speed up again after they cross it. It’s not that hard for HFT and algorithmic trading companies to adjust their algorithms to accommodate with this regulatory change and still do what they think to do.
– Indian regulator proposed that the exchanges to accept orders alternately from a co-location member (whose servers are located in exactly the same physical place as the exchange) and a non co-location member.
Depending upon the cost-benefit analysis, an HFT company can setup a colocation server and a server in proximity to the exchange and alternative sending through those 2 servers of these orders by fixing their strategy.
– Limiting the order to commerce ratios for all marketplace participants.
Technically the algos can work too. But this can surely help reduce some overfishing in the marketplace(i.e. algos sending too many smaller orders at extensive limit prices and then cancelling them to search for trading opportunities which are not easily transparent).
– the regulator of the algos or Particular regulators trying to have HFT and algorithmic players notify the exchange
Its part of Germany and India’s regulatory system, but does not control the automated trading related over- trading triggers as exchanges or the regulators will unable to understand the detailed operation of the algos. They are able to only try and ensure sound risk management is ensured by the HFT firms and follow the practices strictly at the time of audit or algo approval.
– Retail Investor has a disadvantage and cannot get the same arbitrage opportunities due to dearth of access to same technology as HFT and algorithmic businesses
Retail Investor should not be striving to do sub second arbitrage the market in the first place. It’s like saying a cyclist cannot ride as quickly as a car on a high way and car-drivers should be stopped or slowed down. Retail investors should look to take somewhat longer term perspective as they was doing historically.
– Institutional investors can additionally not compete with the HFT companies’ rise in technology
HFT and algorithmic trading firms was driving the use of algorithmic technology and promotion to low latency trading. In their constant RnD process, they’ve stepped up in the technology value chain and have empowered the Institutional investors with efficient and good trading tools at affordable costs. For example, performance algorithms like VWAP, Smart Routers were not available to Institutional Investors a decade or two ago, but HFT companies led RnD and trading styles have made performance algorithms accessible to Retail Investors in addition to other Institutional indirectly. Also, the object of the Institutional Investors is generally to manage portfolios over with longer horizon targets rather than intra-day small price movements.
– HFT companies lead to market catastrophe and failures like Flash Crash in 2010, Knight Capital’s loss in 2012, etc.
In the absence of HFT and low latency algorithmic trading, there had been considerable disasters in the financial business (and in various other industries also) including the LTCM Crisis in 1998, Subprime disaster in 2007, where the human processes have led to major catastrophe in the markets. The use of algorithmic technology if handled well and regulated economically can reduce the probability and scale of such occasions.
For example, If an airplane crashes, it does not make the Air Travel an awful company. Air travel brings lots of benefits to our societal and economical growth that it’s worth it despite unlucky that is uncommon crashes. The regulators in that sector focus on ensuring the safety of passengers and plans is an extreme priority for the airlines.
In the same way, manage and HFT firms recognize the risk management priority and generally target to mitigate risk first, and then focus on profits.
HFT and algorithmic trading businesses actually help in supplying better liquidity in the market, lower cost of trading, tighter spreads, that help institutional investors and retail investors in getting their executions at better costs.
– Visiting extra-taxes on HFT  (like a regulatory proposal out there in Germany). Make it expensive for HFT players and reduce their net profits.
The technology developments that are constructive should be embraced by regulators across the world in financial markets that support growth of the economies and businesses. Their aim should be to understand the market behaviour, advancements in technology, bring transparency to the market, introduce risk management measures like a kill switch (for cancelling all trades when things go wrong), push for stronger pressure testing of automation tools, apply conformity, track patterns that can result in systemic risks, and cause a sound and complete risk management across the financial sector.
