Como Desenvolvedor de Sistemas dedicado e apaixonado, adoro me aventurar no mundo da programação, tanto profissionalmente quanto em meu tempo livre. Dominando Java, Python e MQL5, minha experiência se estende a outras áreas, como SQL, bancos de dados relacionais e não relacionais, PySpark, Hadoop, machine learning, deep learning (utilizando Keras, TensorFlow, Pandas e NumPy), DevOps, engenharia de dados e arquitetura.

Foi em 2016 que, por um feliz acaso, me deparei com o mercado financeiro e me encantei instantaneamente. Ao descobrir a plataforma MetaTrader e sua capacidade de integrar estratégias codificadas ao mercado financeiro, soube que tinha encontrado um novo amor.

Desenvolvendo um agente de Aprendizado por Reforço em MQL5 com Integração RestAPI (Parte 5): Escolhendo o Algoritmo do agente

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.

Developing an MQL5 RL agent with RestAPI integration (Part 4): Organizing functions in classes in MQL5

This article discusses the transition from procedural coding to object-oriented programming (OOP) in MQL5 with an emphasis on integration with the REST API. Today we will discuss how to organize HTTP request functions (GET and POST) into classes. We will take a closer look at code refactoring and show how to replace isolated functions with class methods. The article contains practical examples and tests.

Operating Principle: The "RSDForce" merges trading volume analysis and price movements to provide valuable market insights. Here's how it works: Volume and Price Analysis : The indicator examines the trading volume (quantity of traded assets) and price variations over time. Market Force Calculation : It calculates a value that reflects the market's 'force', indicating whether the price trend is strong and based on substantial trading volume. Simple Visualization : The result is displayed as a

The "ZScore Quantum Edge" is based on an advanced algorithm that combines volume analysis and price movement, providing a clear and accurate representation of market trends. Key Features: In-Depth Trend Analysis : The indicator uses a configurable period for trend analysis, allowing traders to adjust the indicator's sensitivity according to their trading strategies. Data Smoothing : With an adjustable range for data smoothing, the "ZScore Quantum Edge" offers a clearer view of the market

Developing an MQL5 RL agent with RestAPI integration (Part 3): Creating automatic moves and test scripts in MQL5

This article discusses the implementation of automatic moves in the tic-tac-toe game in Python, integrated with MQL5 functions and unit tests. The goal is to improve the interactivity of the game and ensure the reliability of the system through testing in MQL5. The presentation covers game logic development, integration, and hands-on testing, and concludes with the creation of a dynamic game environment and a robust integrated system.

Volume is a widely used indicator in technical analysis, however there is a variation that is even more useful than Volume alone: the Moving Average of Volume. It is nothing more than a moving average applied to the popular Volume indicator. As the name says, Volume + MA serves to display the transacted volume (purchases and sales executed) of a certain financial asset at a given point of time together with the moving average of that same volume over time. What is it for? With the Volume + MA

Semi-uniform strategies were the earliest (and simplest) strategies discovered to approximately solve the bandit problem. All those strategies have in common a greedy behavior where the best lever (based on previous observations) is always pulled except when a (uniformly) random action is taken.
