Articles with MQL5 programming examples

In this article, I will continue the development of TabControl and implement the arrangement of tab headers on all four sides of the control for all modes of setting the size of headers: Normal, Fixed and Fill To Right.

Bulit-in OpenCL support in MetaTrader 5 still has a major problem especially the one about device selection error 5114 resulting from unable to create an OpenCL context using CL_USE_GPU_ONLY, or CL_USE_GPU_DOUBLE_ONLY although it properly detects GPU. It works fine with directly using of ordinal number of GPU device we found in Journal tab, but that's still considered a bug, and users should not hard-code a device. We will solve it by recreating an OpenCL support as DLL with C++ on Linux. Along the journey, we will get to know OpenCL from concept to best practices in its API usage just enough for us to put into great use later when we deal with DLL implementation in C++ and consume it with MQL5.

In this article, I will revise the logic of specifying the base and main objects for all WinForms library objects, develop a new Hint base object and several of its derived classes to indicate the possible direction of moving the separator.

This article presents a sophisticated Expert Advisor for forex trading, combining machine learning with technical analysis. It focuses on trading Apple stock, featuring adaptive optimization, risk management, and multiple strategies. Backtesting shows promising results with high profitability but also significant drawdowns, indicating potential for further refinement.

In this article, I will develop display styles and description text for the progress bar of the ProgressBar control.

Trading across multiple currencies is not available by default when an expert advisor is assembled via the wizard. We examine 2 possible hacks traders can make when looking to test their ideas off more than one symbol at a time.

In the second part of the article, we will move on to the practical implementation of the BSO algorithm, conduct tests on test functions and compare the efficiency of BSO with other optimization methods.

In this article, I will create the functionality for hiding object sections located beyond their containers. Besides, I will create auxiliary arrow button objects to be used as part of other WinForms objects.

In this article, we will look at creating a service app for sending notifications to a smartphone about trading results. We will learn how to handle lists of Standard Library objects to organize a selection of objects by required properties.

In the current article, I will implement the ability to change the properties and appearance of the newly created SplitContainer control.

In this article, I will continue the development of the ProgressBar control. In particular, I will create the functionality for managing the progress bar and visual effects.

Of all the things that we have developed so far, this system, as you will probably notice and eventually agree, is the most complex. Now we need to do something very simple: make our system simulate the operation of a trading server. This need to accurately implement the way the trading server operates seems like a no-brainer. At least in words. But we need to do this so that the everything is seamless and transparent for the user of the replay/simulation system.

The article presents a complete exploration of the Nelder-Mead method, explaining how the simplex (function parameter space) is modified and rearranged at each iteration to achieve an optimal solution, and describes how the method can be improved.

It is sometimes necessary to perform identical operations with a group of files. If you have a list of files included into a group, then it is no problem. However, if you need to make this list yourself, then a question arises: "How can I do this?" The article proposes doing this using functions FindFirstFile() and FindNextFile() included in kernel32.dll.

The article uses block diagrams to examine the logic of the candlestick-based training EAs located in the Experts\Free Robots folder of the terminal.

Among the dozens of examples of how to work with charts, there is a method of manual marking a template. Trend lines, channels, support/resistance levels, etc. are imposed in a chart. Surely, there are some special programs for this kind of work. Everyone decides on his/her own which method to use. In this article, I offer you for your consideration the methods of manual marking with subsequent automating some elements of the repeated routine actions.

The moving averages are by far the best indicators for our AI models to predict. However, we can improve our accuracy even further by carefully transforming our data. This article will demonstrate, how you can build AI Models capable of forecasting further into the future than you may currently be practicing without significant drops to your accuracy levels. It is truly remarkable, how useful the moving averages are.

While manual trading you have to keep an eye on the values of several indicators. It is a little bit different from mechanical trading. If you have two or three indicators and you have chosen a one timeframe for trading, it is not a complicated task. But what will you do if you have five or six indicators and your trading strategy requires considering the signals on the several timeframes?

In this article, I will create the class of an auxiliary panel separator object for the SplitContainer control.
