Este capítulo da série aborda algoritmos de aprendizado por reforço, focando em Q-Learning, Deep Q-Network (DQN), e Proximal Policy Optimization (PPO). Explora como essas técnicas podem ser integradas para melhorar a automação de tarefas, detalhando suas características, vantagens, e aplicabilidades práticas. A seleção do algoritmo mais adequado é vista como crucial para otimizar a eficiência operacional em ambientes dinâmicos e incertos, prometendo discussões futuras sobre a implementação prática e teórica desses métodos.

Este artículo examina la transición de la codificación procedimental a la programación orientada a objetos (POO) en MQL5, enfocándose en la integración con REST APIs. Discutimos la organización de funciones de solicitudes HTTP (GET y POST) en clases y destacamos ventajas como el encapsulamiento, la modularidad y la facilidad de mantenimiento. La refactorización de código se detalla, y se muestra la sustitución de funciones aisladas por métodos de clases. El artículo incluye ejemplos prácticos y pruebas.

В этой статье рассматривается реализация автоматических ходов в игре "Крестики-нолики" на языке Python, интегрированная с функциями MQL5 и модульными тестами. Цель - улучшить интерактивность игры и обеспечить надежность системы с помощью тестирования на MQL5. Изложение охватывает разработку игровой логики, интеграцию и практическое тестирование, а завершается созданием динамической игровой среды и надежной интегрированной системы.

In this article we will talk about how MQL5 can interact with Python and FastAPI, using HTTP calls in MQL5 to interact with the tic-tac-toe game in Python. The article discusses the creation of an API using FastAPI for this integration and provides a test script in MQL5, highlighting the versatility of MQL5, the simplicity of Python, and the effectiveness of FastAPI in connecting different technologies to create innovative solutions.

In this article we will talk about the importance of APIs (Application Programming Interface) for interaction between different applications and software systems. We will see the role of APIs in simplifying interactions between applications, allowing them to efficiently share data and functionality.

This article describes the implementation of a regression model based on a decision tree. The model should predict prices of financial assets. We have already prepared the data, trained and evaluated the model, as well as adjusted and optimized it. However, it is important to note that this model is intended for study purposes only and should not be used in real trading.

This material provides a complete guide to creating a class in MQL5 for efficient management of CSV files. We will see the implementation of methods for opening, writing, reading, and transforming data. We will also consider how to use them to store and access information. In addition, we will discuss the limitations and the most important aspects of using such a class. This article ca be a valuable resource for those who want to learn how to process CSV files in MQL5.

The multilayer perceptron is an evolution of the simple perceptron which can solve non-linear separable problems. Together with the backpropagation algorithm, this neural network can be effectively trained. In Part 3 of the Multilayer Perceptron and Backpropagation series, we'll see how to integrate this technique into the Strategy Tester. This integration will allow the use of complex data analysis aimed at making better decisions to optimize your trading strategies. In this article, we will discuss the advantages and problems of this technique.

There is a Python package available for developing integrations with MQL, which enables a plethora of opportunities such as data exploration, creation and use of machine learning models. The built in Python integration in MQL5 enables the creation of various solutions, from simple linear regression to deep learning models. Let's take a look at how to set up and prepare a development environment and how to use use some of the machine learning libraries.

The popularity of these two methods grows, so a lot of libraries have been developed in Matlab, R, Python, C++ and others, which receive a training set as input and automatically create an appropriate network for the problem. Let us try to understand how the basic neural network type works (including single-neuron perceptron and multilayer perceptron). We will consider an exciting algorithm which is responsible for network training - gradient descent and backpropagation. Existing complex models are often based on such simple network models.
