Articles with MQL5 programming examples

The article considers several methods of applying the Moving Average indicator. Each method involving a curve analysis is accompanied by indicators visualizing the idea. In most cases, the ideas shown here belong to their respected authors. My sole task was to bring them together to let you see the main approaches and, hopefully, make more reasonable trading decisions. MQL5 proficiency level — basic.

Many workstations contain some representative image which shows something about the user. These images make the working environment more beautiful and exciting. Let's see how to make the charts more interesting by adding a background.

In this article, I will consider the implementation of the independent dragging of any form objects using a mouse. Besides, I will complement the library by error messages and new deal properties previously implemented into the terminal and MQL5.

The article considers the use of the CCanvas class in MQL applications. The theory is accompanied by detailed explanations and examples for thorough understanding of CCanvas basics.

In this article, I will start creating the functionality for handling mouse events in form objects, as well as add new properties and their tracking to a symbol object. Besides, I will improve the symbol object class since the chart symbols now have new properties to be considered and tracked.

In this article, I will consider the toolkit for managing composite graphical objects - controls for managing an extended standard graphical object. Today, I will slightly digress from relocating a composite graphical object and implement the handler of change events on a chart featuring a composite graphical object. Besides, I will focus on the controls for managing a composite graphical object.

In this article, I will start the development of various composite graphical object events. We will also partially consider moving and deleting a composite graphical object. In fact, here I am going to fine-tune the things I implemented in the previous article.

In this article, I will start developing the functionality for creating composite graphical objects. The library will support creating composite graphical objects allowing those objects have any hierarchy of connections. I will prepare all the necessary classes for subsequent implementation of such objects.

In the article, I will create the class of the standard graphical object memory allowing the object to save its states when its properties are modified. In turn, this allows retracting to the previous graphical object states.

In this article, I will refine the basic functionality for providing control over graphical object events from a library-based program. I will start from implementing the functionality for storing the graphical object change history using the "Object name" property as an example.

In this article, I will implement the basic functionality for tracking standard graphical object events. I will start from a double click event on a graphical object.

Currently, the library is able to track standard graphical objects on the client terminal chart, including their removal and modification of some of their parameters. At the moment, it lacks the ability to create standard graphical objects from custom programs.

In this article, we will further develop the idea of drawing graphical objects on charts using keyboard shortcuts. New tools have been added to the library, including a straight line plotted through arbitrary vertices, and a set of rectangles that enable the evaluation of the reversal time and level. Also, the article shows the possibility to optimize code for improved performance. The implementation example has been rewritten, allowing the use of Shortcuts alongside other trading programs. Required code knowledge level: slightly higher than a beginner.

In this article, I offer my set of trading functions in the form of a ready-made EA. This method allows getting multiple trading strategies by simply adding indicators and changing inputs.

In this article, I will create a dynamic multidimensional array class with the ability to change the amount of data in any dimension. Based on the created class, I will create a two-dimensional dynamic array to store some dynamically changed properties of graphical objects.

In this article, I will continue my work on tracking standard graphical object events and create the functionality allowing users to control changes in the properties of graphical objects placed on any charts opened in the terminal.

In this article, I will consider tracking property value modification, as well as removing and renaming graphical objects in the library.

Do you wish to become a successful Freelance developer on MQL5? If the answer is yes, this article is right for you.

In this article, I will complete the development of the descendant classes of the abstract graphical object class and start implementing the ability to store these objects in the collection class. In particular, I will create the functionality for adding newly created standard graphical objects to the collection class.

In this article, I will consider creation of descendant objects for the terminal abstract standard graphical object. The class object describes the properties that are common for all graphical objects. So, it is simply some kind of a graphical object. To clarify its affiliation with a real graphical object, we need to set the properties inherent in this particular graphical object in the descendant object class.

It's not always all about writing the code that leads to effective coding. There are certain habits that I have found in my experience that lead to effective coding. We are going to discuss some of them in detail in this article. This is a must-read article for every programmer who wants to improve their ability to write complex algorithms with less hassle.

In this article, I will create the class of the abstract graphical object. This object is to serve as a basis for creating the class of standard graphical objects. Graphical objects feature multiple properties. Therefore, I will need to do a lot of preparatory work before actually creating the abstract graphical object class. This work includes setting the properties in the library enumerations.

Determing the broker offset and GMT automatically. Instead of asking the support of your broker, from whom you will probably receive an insufficient answer (who would be willing to explain a missing hour), we simply look ourselves how they time their prices in the weeks of the time changes — but not cumbersome by hand, we let a program do it — why do we have a PC after all.

In this article, I will improve all library objects by assigning a unique type to each object and continue the development of the library graphical objects collection class.

It is time to start the integration of the already created objects into the previously created library objects. This will ultimately endow each library object with its own graphical object allowing users to interact with the program.

Every developer wants to be able to write code faster, and being able to code faster and effective is not some kind of special ability that only a few people are born with. It's a skill that can be learned, that is what I'm trying to teach in this article.

In this article, I will optimize the code of classes from the previous articles and create the geometric animation frame object class allowing us to draw regular polygons with a given number of vertices.

In this article I will address the possibilities of creating customized indicators with candlesticks, pointing out their advantages and disadvantages.

In this article, I will develop the class of a single animation frame and its descendants. The class is to allow drawing shapes while maintaining and then restoring the background under them.

Every developer wants to be able to write code faster, and being able to code faster and effective is not some kind of special ability that only a few people are born with. It's a skill that can be learned by every coder, regardless of years of experience on the keyboard.

This is the must-read article for anyone wanting to improve their programming career. This article series is aimed at making you the best programmer you can possibly be, no matter how experienced you are. The discussed ideas work for MQL5 programming newbies as well as professionals.

In this article, I will define the animation principles to be used in some parts of the library. I will also develop a class for copying a part of the image and pasting it to a specified form object location while preserving and restoring the part of the form background the image is to be superimposed on.

There are a lot of bad habits that newbies and even advanced programmers are doing that are keeping them from becoming the best they can be to their coding career. We are going to discuss and address them in this article. This article is a must read for everyone who wants to become successful developer in MQL5.
