Seeking Alpha - Basic Programming For MT4 Currency Trading




Programming is a common language used in software industry and with the release of MetaTrader trading platform, it introduce a programming language with is similar to C into the Forex Trading world.

With programming, Forex Trader can put their winning strategy into programming codes and run on MT4 trading platform to let the computer trades automatically. This is make possible using MQL or metaquotes languages to write and compile using metaeditor into executable ex files which are called expert advisor to run on MT4 trading account.

The programming is similar to C with declaration of variables, logic comparision and executing of files and functions.

Variables

MQL4 comes with various data types namely integer, Boolean, character, string, float, color and date & time. You can create local variable can using the standard declaration like int, double, string, etc. For global variables, you have to declare the variables before int start. To have your variable available and value retained after program ended, use static variable declaration by static int, static double, etc

Standard Constants

It comes with many standard constant that you can use which is already predefine by the program. One of the most important standard constants are time frame which comes with PERIOD_M1, PERIOD_M5, PERIOD_M15, PERIOD_M30, PERIOD_H1, PERIOD_H4, PERIOD_D1, PERIOD_W1 and PERIOD_MN1. This is useful in defining the currency chart to use for technical indicator trigger. Next is the OrderSend function which uses trade operations constant OP_BUY, OP_SELL, OP_BUYLIMIT, OP_SELLLIMT, OP_BUTSTOP and OP_SELLSTOP which covers all the 6 different trade execution. The last importance standard constant is price related which is PRICE_CLOSE, PRICE_OPEN, PRICE_HIGH and PRICE_LOW which is often used in technical charting.


Predefined Variables

Ask, Bars, Bid, Close, Digits, High, Low, Open, Point and Time are widely use thru out the programming codes. When comparing currency price, Ask, Bid, Close, Open, High and Low are often called for operand operation. Bars is used when counting the number of bars in the selected currency chart. Point is the current symbol point value in the quote currency and Digits is the number after decimal point for the current symbol price. Both are used to compute stop loss, profit take, buy and sell price.

Account Information

This is a group of function which provided important information about your trading account and is used for computing trading lots and money management system including calculating of margin and balance. The often used function are AccountBalance, AccountFreeMargin, AccountLeverage, AccountMargin and AccountProfit. You need to input some margin requirement and usually I use minimum 200% margin requirement for maximum open lots using account leverage for maximum drawdown to avoid margin call.

Date and Time Functions

The widely used functions are DayOfWeek to get the Monday to Sunday of the date, Hour and minute for time and Seconds for looping. If your strategy is time constraint, meaning it only run during 2 to 4 am and only on Monday to Wednesday, this group of function is definitely the ones that you called to compare and execute codes.

Technical Indicators

This is the most important functions you be calling if you are using technical charting to execute trading rules. The common indicator that I used are iMA which is moving average simple/exponential/linear weighted calculation, iRSI which is Relative Strength Index, iMACD which is Moving Average Convergence/Diverage, iBands which is Bollinger Bands, iCCI which is Commodity Channel Index, iStochastic which is Stochastic Oscillator and iADX which is Movement Directional Index.

Trading Functions

This is required for any trading to be successful. The widely used trade function are OrderSend, OrderSelect, OrderClose and OrderModify. You may refer to MQL4 documentation for more information of the various functions. And refer to my website for more software offers with ready to use program codes.

How did trader, John W. Henry, start out as a farmer and end up a billionaire and owner of, first the Florida Marlins and now, the Boston Red Sox? How do traders like Bill Dunn, Ed Seykota and Keith Campbell continually pull profits in the hundreds of millions from both bull and bear markets? The answer is that they are trend followers. Trend following is the only strategy to consistently make money in the markets. Leading expert Michael Covel reveals the underground network of these little-known traders and hedge fund managers who have practiced trend following for years. He pulls back the veil on their strategies by introducing the basic concepts/techniques of trend following such as why the market price contains all the information a trader needs. Covel rigorously reviews and analyzes years of detailed performance data to prove without question that trend following works. He breaks down trend following strategies including how to make volatility work; how to control risk; and how to make successful trading decisions "from the gut."Covel shows why trend following is ideal for individual traders who self-manage their portfolios or for the individual investor searching for a new type of investment advisor. Along the way he debunks an immense amount of misinformation/failed advice from pros who ought to know better. This timely book capitalizes on today's massive move back into the markets and investors' renewed determination to find strategies that really work.

Review

A recent interview with Michael Covel on Bloomberg Radio (6.5 MB MP3 audio file) about trend following.
"Please read [Trend Following] whether you think you have an interest in trend following or are not quite sure. I guarantee you will be happy that you took the time. It, of course, covers how trend following works, how it's done, and who can do it, and it doesn't beat around the bush with generalities. Again, get this book. Covel has hit a homerun with it."
Gail Osten, Editor-in-Chief
Stocks, Futures & Options Magazine
Official Journal for Personal Investing in Stocks, Futures and Options

"A mandatory reference for anyone serious about alternative investments."
Jon Sundt, President and CEO of Altegris

"Michael Covel does an excellent job of educating his readers about the little-known opportunities available to them through one of the proven best hedge fund strategies. This book is like gold to any smart investor."
Christian Baha, CEO, Superfund

"A most interesting book -- definitely a 'must have' on your shelf. Pull out the plastic and get it!...Trend Following is well constructed, well written and an excellent distillation of the research undertaken by the author. Backed up by trading 'legends' like Ed Seykota, it convincingly argues that the most successful trading systems are based on trend following...While you may read the book in bed, especially the first time, it is best read at a desk with a notepad handy. While seeming to come from the perspective of technical analysis it is still a very good book on trading psychology...The book is both a great read and an insightful textbook for all traders and investors."

Preface

"Men wanted for hazardous Journey. Small wages. Bitter cold. Long months of complete darkness. Constant danger. Safe return doubtful. Honor and recognition in case of success."1
This book is the result of an eight-year "hazardous journey" for the truth about Trend Following. It fills a void in a marketplace inundated with books about finance and trading but lacking any resource or, for that matter, practically any reference to what we believe is the best strategy to consistently make money in the markets. That strategy is known as Trend Following:
"Let's break down the term 'Trend Following' into its components. The first part is 'trend.' Every trader needs a trend to make money. If you think about it, no matter what the technique, if there is not a trend after you buy, then you will not be able to sell at higher prices . . . 'Following' is the next part of the term. We use this word because trend followers always wait for the trend to shift first, then 'follow' it."2
When it is a question of money, everyone is of the same religion.
Voltaire
Trend Following seeks to capture the majority of a trend, up or down, for profit. It trades for profits in the major asset classes—stocks, bonds, currencies, and commodities. However simple the basic concepts about Trend Following are, they have been widely misunderstood. Our desire to correct this state of affairs is what, in part, launched our research. We wanted to be as objective as possible, so we based our writing on the available data:
  • Trend followers' month-by-month performance histories.
  • Trend followers' published words and comments over the last 30 years.
  • News accounts of financial disasters.
  • News accounts of the losers in those financial disasters.
  • Charts of markets traded by trend followers.
  • Charts of markets traded by losers in the financial disasters.
Education rears disciples, imitators, and routinists, not pioneers of new ideas and creative geniuses. The schools are not nurseries of progress and improvement, but conservatories of tradition and unvarying modes of thought.
Ludwig von Mises
If we could have developed a book comprised of only numbers, charts, and graphs of Trend Following performance data, we would have. However, without any explanation, few readers would have appreciated all of the ramifications of what the data showed. Therefore our approach to writing Trend Following became similar to the one Jim Collins describes in Good to Great, in which a team of researchers generated questions, accumulated data in their open-ended search for answers, and then energetically debated it.
Trend followers we studied form a sort of underground network of relatively unknown traders who, except for an occasional article, the mainstream press has virtually ignored. What we have attempted to do is lift the veil, for the first time, on who these enormously successful traders are, how they trade, and what is to be learned from their approach to trading that we might apply to our own portfolios.
Trend Following challenges much of the conventional wisdom about successful trading. We were determined to avoid being influenced by knowledge institutionalized and defined by Wall Street. We were adamant about fighting "flat earth" thinking. During our research, we tried to avoid starting with an assumption and then finding the data to support it. Instead we asked the question and then, objectively, doggedly, and slowly, let the answer reveal itself.
If there was one factor that motivated us to work in this manner, it was simple curiosity. The more we uncovered about trend followers, the more we wanted to know. For example, one of our earliest questions was who profited when Barings Bank collapsed in 1995. Our search unearthed Barings Bank–related performance data including that of trend follower John W. Henry (now the majority owner of the Boston Red Sox). His track record generated new questions, such as, "How did he discover Trend Following in the first place?" and "Has his approach changed in any significant way in the past 20 years?"
We were also curious about who won the $1.9 billion Long Term Capital Management lost during August and September 1998. We wanted to know why the biggest banks on Wall Street would invest $100 billion in an options pricing model, Nobel prize–winning or not. Further, considering what mutual fund managers have lost in the past few years and what successful trend followers have earned during the same time period, we could not understand why so few investors know anything about Trend Following. We also became interested in:
  • How trend followers win in the zero-sum game of trading.
  • Why Trend Following has been the most profitable style of trading.
  • The philosophical framework of trend followers' success.
  • Timeless principles of Trend Following.
  • The Trend Following worldview of market behavior.
  • Reasons why Trend Following is so enduring.
The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.
Sir William Bragg
Many of the trend followers we studied are reclusive and extremely low key. Some discovered Trend Following on their own and used it to make their fortunes out of home offices. Bill Dunn, a successful trend follower who has beaten the markets for over 25 years, works out of a quiet, spartan office in a Florida coastal town. For Wall Street, this approach to trading is tantamount to sacrilege. It goes against all the customs, rituals, trappings, and myths we have grown accustomed to associating with Wall Street success. In fact, it is our hope that our profiles of trend followers will correct the public's misconception of a successful trader as a harried, intense workaholic who spends 24/7 in the labyrinth of a Wall Street trading firm, surrounded by monitors and screaming into a phone.
We've assembled the first comprehensive look at Trend Following, but this is neither a course nor the only resource you will ever need. It is to be used in conjunction with our Web site at http://www.trendfollowing.com. We have tried to be comprehensive with our definitions. However, if we mention an unfamiliar word, name or reference a source you haven't heard of, please go to Google (http://www.google.com).
Fish see the bait, but not the hook; men see the profit, but not the peril.
Chinese Proverb
We have tried to make the material accessible and interesting enough so it might give you an occasional "aha" experience. However, if you're looking for trading "secrets," you need to look elsewhere. There are none. If you're in the mood for stories about what it's like inside a typical Wall Street firm or how greedy traders sow the seeds of their destruction, like in Den of Thieves, or Barbarians at the Gate, we will not meet your needs.
You may have noticed that I use "we" instead of "I" when describing the process of writing this book. That's because it could not have been written without the generosity of the traders, professors, investors, colleagues, and friends who graciously shared their wisdom and trading experiences with me. Without their support, hard work, long hours, and creativity, Trend Following would still be an ongoing hazardous journey. So if there is any "honor and recognition" to be given, it is to everyone who participated, not just the person whose name appears on the cover.
To be aware how fruitful the playful mood can be is to be immune to the propaganda of the alienated, which extols resentment as a fuel of achievement.
Eric Hoffer

Unlike other books that focus on the complex mathematical theories behind money management, this book presents its system in straightforward, easy-to-understand terms that will allow you to quickly see how these concepts work and immediately benefit from the value of effectively managing risk.

From the Inside Flap

Risk control tends to be the last thing that most traders focus on, perhaps because of the popular belief that it's their trading strategy that will generate great fortunes. But ultimately, a strategy alone won't create riches. A trader or investor needs to develop discipline, a strong financial psychology, and a sound money management system to maximize profits and keep them out of financial danger. In A Trader's Money Management System, veteran trader Bennett McDowell offers readers an expert guide to the most important elements of money management in trading.McDowell shares his personal money management system, with the ultimate goal of helping you design your own system, customized to fit your risk tolerance, your experience level, and financial needs. He identifies the six types of risk to consider every time you make a trade—trade risk, market risk, margin risk, liquidity risk, overnight risk, and volatility risk—covering each in detail.
In easy-to-understand terms, the author then breaks down his system into five key elements. He first explains the psychology of risk control, telling what issues to look for and how to address them in order to more effectively implement your money management system. McDowell then details a variety of stop-loss approaches and gives you tips on how to make sure you adhere to them when they're hit. He follows with a discussion of trade size, showing how to determine how large or small your trade size should be so that you are not overextending your risk. McDowell then covers the crucial element of record keeping, and explains how it pays significant dividends. Finally, he shows how to design a realistic personal plan—one that you will continue to use and profit from.
This book also equips readers with two valuable tools: A one-month free trial of Trade Size Calculator software and The Trader's Assistant recordkeeping materials. The trial Trade Size Calculator software is downloadable at www.traderscoach.com (see Appendix A for details), and The Trader's Assistant recordkeeping materials can be photocopied directly from the book. These two tools complement the text and together provide a complete package that will deliver better results to your bottom line.
