Trading with the MQL5 Economic Calendar (Part 12): SQLite Storage and Deduplication

Trading with the MQL5 Economic Calendar (Part 12): SQLite Storage and Deduplication

In this article, we replace the embedded CSV snapshot with a SQLite layer that persists calendar events and triggered trade IDs across restarts. The database lives in the common terminal folder and is shared by live charts and the strategy tester, so both modes read the same data without recompiling. An on-demand downloader with a canvas progress bar fetches history from the calendar API and stores it for offline reuse.

Kohonen Self-Organizing Maps in an MQL5 Expert Advisor

Kohonen Self-Organizing Maps in an MQL5 Expert Advisor

Kohonen's self-organizing maps transform the chaos of market data into an ordered two-dimensional map, where similar patterns are grouped together. The article demonstrates a complete implementation of a SOM in an MQL5 Expert Advisor with 400 neurons and continuous learning. We break down the Best Matching Unit search algorithm, weight updates using a Gaussian neighborhood function, integration with quantum effects, and the generation of trading signals. The code is open-source, the math is clear, and the results are verifiable.

Building an Object-Oriented Session VWAP Engine in MQL5

Building an Object-Oriented Session VWAP Engine in MQL5

This article shows how to implement a session vwap in MQL5 as a reusable include class with a strict daily reset at broker midnight. The engine computes VWAP and volume‑weighted deviation bands only on closed bars and anchors accumulation with MqlDateTime to avoid distortions from missing candles. A companion indicator plots the baseline and bands, while an Expert Advisor reads signals once per bar for consistent, CPU‑efficient execution and reliable testing.

Building Automated Daily Trading Reports with the SendMail Function

Building Automated Daily Trading Reports with the SendMail Function

We build an MQL5 Expert Advisor that emails a structured daily trading report. The article shows how to configure SMTP in MetaTrader 5, collect and filter closed trades for the previous day, compute totals for profit, wins, losses, and trade count, and assemble account details into the subject and body. You also schedule one send per day and prevent duplicates using daily candle detection.

Automating Trading Strategies in MQL5 (Part 51): The Bread and Butter Judas Swing Model with Premium and Discount

Automating Trading Strategies in MQL5 (Part 51): The Bread and Butter Judas Swing Model with Premium and Discount

We build a session-based reversal program in MQL5 using the Bread and Butter Judas Swing model. It derives a higher-timeframe daily bias, defines New York kill zones, maps each session's premium and discount from the live range, and requires a sweep before a market structure shift confirms entry. Readers get a ready approach to arm setups only during active sessions and execute in the bias direction with clear, testable rules.

MQL5 Trading Tools (Part 36): Adding Shape and Annotation Tools with In-Place Label Editing to the Canvas Drawing Layer

MQL5 Trading Tools (Part 36): Adding Shape and Annotation Tools with In-Place Label Editing to the Canvas Drawing Layer

We add eight shape tools and nine annotation tools to the canvas and implement a full in-place label-editing system. The article walks through geometry, AA rendering, shared word-wrap and supersampled text helpers, and the caret-driven state machine for typing, navigation, and selection. This yields a complete, consistent annotation toolkit with editable labels that plugs into the prior interaction pipeline.

Building a Synthetic Custom Symbol in MQL5 Using Multi-Symbol Price Averaging

Building a Synthetic Custom Symbol in MQL5 Using Multi-Symbol Price Averaging

This article shows how to build a synthetic custom symbol in MQL5 by averaging OHLC data from multiple instruments into a single derived price series. It covers symbol collection and validation, custom symbol creation and configuration, timestamp alignment, historical reconstruction, and lightweight live updates. The result is a reusable method for creating synthetic instruments suitable for correlation analysis, index-style modeling, indicator development, and strategy testing.

Monochronic Trading (Part 1): How to Detect Broker Timezone and DST in MQL5

Monochronic Trading (Part 1): How to Detect Broker Timezone and DST in MQL5

We describe an MQL5 framework that aligns entries with session rhythms and scheduled clock events. A script identifies the broker's time zone and DST by detecting NFP spikes on EURUSD and matching them to EU/US/AU transition dates, producing EA‑ready settings. Session-to-broker time conversion and 15-minute marks constrain execution. A multi‑timeframe AMA signal aggregates trends for strategy selection and optimization.

Overcoming Accessibility Problems in MQL5 Trading Tools (Part V): Gesture-Based Trading With Computer Vision

Overcoming Accessibility Problems in MQL5 Trading Tools (Part V): Gesture-Based Trading With Computer Vision

This article shows how to build a hands-free trading workflow for MetaTrader 5 by translating webcam-tracked hand gestures into MQL5 trade commands. We cover the architecture (MediaPipe/OpenCV in Python plus an MQL5 EA), gesture-to-action mapping, and interprocess communication via Global Variables or HTTP polling. You will implement the EA, execute BUY/SELL/CLOSE actions, and validate latency and reliability under real‑time conditions.

A Reinforcement Learning System for Algorithmic Trading in MQL5

A Reinforcement Learning System for Algorithmic Trading in MQL5

The article describes the development of a multi-agent machine learning system for algorithmic trading on MetaTrader 5 based on reinforcement learning. The system has a three-tier architecture: memory neurons store experience, agents make independent decisions, and the collective mind combines them through weighted voting. The system is continuously improved through Q-learning, pruning of ineffective neurons, and evolutionary reduction of exploration.

Engineering a Self-Healing Expert Advisor in MQL5 (Part 3): Restart-Aware Breakeven and Trailing Systems

Engineering a Self-Healing Expert Advisor in MQL5 (Part 3): Restart-Aware Breakeven and Trailing Systems

Building on Part 2, the implementation introduces restart-aware breakeven and trailing-stop systems for MetaTrader 5. The EA persists the state, such as breakeven activation, last trailing price, and virtual SL in SQLite, then restores them on startup. This preserves dynamic protection flow and prevents lost progress after terminal interruptions.
