If we thoroughly examine any complex trading system, we will see that it is based on a set of simple trading signals. Therefore, there is no need for novice developers to start writing complex algorithms immediately. This article provides an example of a trading system that uses semaphore indicators to perform deals.
The article gives a description of ways of use of the multiple regression analysis for development of trading systems. It demonstrates the use of the regression analysis for strategy search automation. A regression equation generated and integrated in an EA without requiring high proficiency in programming is given as an example.
This article seeks to upgrade the indicator created earlier on and briefly deals with a method for estimating forecast confidence intervals using bootstrapping and quantiles. As a result, we will get the forecast indicator and scripts to be used for estimation of the forecast accuracy.
In the article "Dr. Tradelove..." we created an Expert Advisor, which independently optimizes parameters of a pre-selected trading system. Moreover, we decided to create an Expert Advisor that can not only optimize parameters of one trading system underlying the EA, but also select the best one of several trading systems. Let's see what can come of it...
Hiding of the implementation details of classes/functions in an .ex5 file will enable you to share your know-how algorithms with other developers, set up common projects and promote them in the Web. And while the MetaQuotes team spares no effort to bring about the possibility of direct inheritance of ex5 library classes, we are going to implement it right now.
Most developers need to have their code secured. This article will present a few different ways to protect MQL5 software - it presents methods to provide licensing capabilities to MQL5 Scripts, Expert Advisors and Indicators. It covers password protection, key generators, account license, time-limit evaluation and remote protection using MQL5-RPC calls.
The purpose of this article is to create the most simple trading strategy that implements the "All or Nothing" gaming principle. We don't want to create a profitable Expert Advisor - the goal is to increase the initial deposit several times with the highest possible probability. Is it possible to hit the jackpot on ForEx or lose everything without knowing anything about technical analysis and without using any indicators?
When developing a trading system, there usually arises a problem of selecting the best combination of indicators and their signals. Discriminant analysis is one of the methods to find such combinations. The article gives an example of developing an EA for market data collection and illustrates the use of the discriminant analysis for building prognostic models for the FOREX market in Statistica software.
How many cores do you have on your home computer? How many computers can you use to optimize a trading strategy? We show here how to use the MQL5 Cloud Network to accelerate calculations by receiving the computing power across the globe with the click of a mouse. The phrase "Time is money" becomes even more topical with each passing year, and we cannot afford to wait for important computations for tens of hours or even days.
The MQL5 program usability is determined by both its rich functionality and an elaborate graphical user interface. Visual perception is sometimes more important than fast and stable operation. Here is a step-by-step guide to creating display panels on the basis of the Standard Library classes on your own.

The interactive graphical environment simplifies the design process and eliminates the need to write MQL5 code.
The market price is formed out of a stable balance between demand and supply which, in turn, depend on a variety of economic, political and psychological factors. Differences in nature as well as causes of influence of these factors make it difficult to directly consider all the components. This article sets forth an attempt to predict the market price on the basis of an elaborated regression model.
This article is a logical continuation of my article Statistical Probability Distributions in MQL5 which set forth the classes for working with some theoretical statistical distributions. Now that we have a theoretical base, I suggest that we should directly proceed to real data sets and try to make some informational use of this base.
This is the last of the three articles devoted to graphical controls. It covers the creation of the main graphical interface component - the form - and its use in combination with other controls. In addition to the form classes, CFrame, CButton, CLabel classes have been added to the control library.
This article describes how object-oriented programming can be used for creating multi-timeframe and multi-currency panels for MetaTrader 5. The main goal is to build a universal panel, which can be used for displaying many different kinds of data, such as prices, price changes, indicator values or custom buy/sell conditions without the need to modify the code of the panel itself.
On the eleventh week of the Automated Trading Championship, Andrea Zani (sbraer) got featured very close to the top five of the competition. It is on the sixth place with about 47,000 USD now.

If you are interested on how to implement and analyze different statistics from ATC 2011 in real time, this article is just for you.
The task of writing an Expert Advisor trading on multiple currency pairs is complex both in terms of finding suitable strategies and from the technological side. But if the goal is set clear, nothing is impossible then. It was four times already that Vitaly Mazurenko (notused) submitted his multi-currency Expert Advisor. It seems, he has managed to find the right way this time.
You don't need to know what are polymorphism, encapsulation, etc. all about in to use object-oriented programming (OOP)... you may simply use these features. This article covers the basics of OOP with hands-on examples.
Since the first Automated Trading Championship we have seen plenty of trading robots in our TOP-10 created with the use of various methods. Excellent results were shown both by the Exper Advisors based on standard indicators, and complicated analytical complexes with weekly automatic optimization of their own parameters.
It was only this summer that Vitaly Antonov (beast) has learned about the upcoming Automated Trading Championship and got to know MetaTrader 5 terminal. Time was running out, besides, Vitaly was a newcomer. So, he randomly chose GBPUSD currency pair to develop his trading system. And the choice turned out to be successful. It would have been impossible to use other symbols with the strategy.
The article addresses probability distributions (normal, log-normal, binomial, logistic, exponential, Cauchy distribution, Student's t-distribution, Laplace distribution, Poisson distribution, Hyperbolic Secant distribution, Beta and Gamma distribution) of random variables used in Applied Statistics. It also features classes for handling these distributions.
I think financial markets are like manic-depressive patients. Sell when they have mania, and buy when they have depression. The envelope helps me determine where these levels of depression and mania are. There is a joke: "A neurotic is a man who builds castles in the skies, psychotic is the one who lives in them, and a psychiatrist is a person who collects the rent." I want to be a psychiatrist in the market. I want to collect the rent from the madness of the crowd.
There is no trouble finding the Holy Grail of testing, it is however much more difficult to get rid of it. This article addresses the selection of the Expert Advisor operating parameters with automated group processing of optimisation and testing results upon maximum utilisation of the Terminal performance capabilities and minimum end user load.
Interview with Boris Odintsov (bobsley) is the last one within the ATC Champions League project. Boris won the Automated Trading Championship 2010 - the first Championship held for the Expert Advisors in the new MQL5 language. Having appeared in the top ten already in the first week of the ATC 2010, his EA brought it to the finish and earned $77,000. This year, Boris participates in the competition with the same Expert Advisor with modified settings. Perhaps the robot would still be able to repeat its success.
Just over a year ago joo, in his article "Genetic Algorithms - It's Easy!", gave us a tool for implementation of the genetic algorithm in MQL5. Now utilizing the tool we will create an Expert Advisor that will genetically optimize its own parameters upon certain boundary conditions...
The Expert Advisor by Ge Senlin (yyy999) from China got featured in the top ten of the Automated Trading Championship 2011 in late October and hasn't left it since then. Not often participants from the PRC show good results in the Championship - Forex trading is not allowed in this country. After the poor results in the previous year ATC, Senlin has prepared a new multicurrency Expert Advisor that never closes loss positions and uses position increase instead. Let's see whether this EA will be able to rise even higher with such a risky strategy.
