This article adds a symbol metadata layer to the MQL5 portfolio framework, normalizing contract specifications across instruments with different tick sizes and profit currencies. A CSymbolRegistry class loads a symbol universe from file, queries broker data, and converts tick values into account currency, including cross-rate and CFD tick/point cases. The Portfolio Controller publishes per-symbol lot limits from this metadata, and Instrument Agents recover automatically once the controller becomes available.

This work delivers an MQL5 Expert Advisor that reads open-position symbols, builds return series, and computes a rolling Pearson correlation matrix, displayed as a CCanvas heatmap. Off-diagonal pairs that meet a warning threshold are bordered for quick scanning. The code details return processing, correlation arithmetic, and matrix indexing, with a verification script, helping you track shifting co-movements across your active book.

This article builds an MQL5 dashboard that evaluates entry timing for closed positions using tick‑based Maximum Adverse Excursion (MAE) and Maximum Favorable Excursion (MFE). It computes an entry efficiency ratio, renders an MAE/MFE scatter plot and an efficiency histogram, and prints a concise summary to the Experts tab. Deal grouping, tick‑level excursion logic, and a standalone verification script are included so you can diagnose entry quality across many trades.

The article presents an MQL5 script that reads closed deals, groups them by date, and renders a calendar grid for daily P&L and trade count. It explains the data model, normalization to midnight, robust week/weekday mapping, diverging and single-hue color scales, and CCanvas-based drawing, plus a verification script and weekday summary. This helps you quickly locate clusters and quiet periods and cross-check findings with logged totals.

This article presents an MQL5 script that extracts closed trade history, computes empirical win rate and payoff, and evaluates consecutive-loss probabilities using the geometric tail, plus risk of ruin from edge and position size. It plots a CCanvas ruin curve with a live marker at the chosen risk and prints a probability summary, including the account's worst historical streak in theoretical context.

This MQL5 dashboard aggregates closed deals by symbol and UTC hour, calculates win rate and average reward‑to‑risk, and displays the results as two color‑coded heatmaps. A companion table in the Experts tab highlights the strongest and weakest symbol/hour cells, with an option to require a minimum trade count to reduce noise.

The article presents a compact dashboard that relates trade duration to net profit using MQL5 and CCanvas. It pulls closed deals, derives duration in minutes, and renders a log‑scaled scatter by symbol, with an overlaid least‑squares line and R². A bucketed duration view identifies which hold‑time range produced the highest average result, helping assess exit timing.

A modular MQL5 toolkit computes and visualizes rolling Profit Factor over fixed trade-count windows. It presents the statistical motivation, an incremental algorithm that avoids recomputation, and a dedicated CCanvas rendering pipeline. The dashboard adds reference lines, shading for weak periods, and summary metrics, while a separate test suite validates the math, giving a practical way to monitor stability and detect deterioration in strategy behavior.

We build a drawdown analytics dashboard that derives the equity curve from deals and finds every episode's depth and recovery duration. Results appear on a CCanvas timeline spaced by point index with alternating bold annotations, and in a terminal table sorted by duration, allowing you to prioritize risk by time spent underwater rather than depth alone.

This article builds an MQL5 dashboard that classifies closed deals into Sydney, Tokyo, London, and New York trading sessions by UTC close time. It computes per-session P&L, win rate, and average hold time, then renders the results as a persistent CCanvas bar chart with an account-wide summary row, alongside an Experts tab summary table. A verification script confirms the classification and metrics logic behaves correctly.

A file-based news filter for MQL5 reads a pre-downloaded Forex Factory CSV from MQL5/Files, avoiding fragile web scraping and paid APIs. It provides a modular CNewsFilter with a quote-aware CSV parser, suffix-robust currency extraction, an inclusive time-window checker with clear block reasons, and chart zones for today's events. A demo EA and assertion tests help you integrate and verify offline filtering around scheduled releases.

This article implements a typed message bus over Windows named pipes to replace MetaTrader's untyped GlobalVariables for inter‑EA communication. A broker EA manages the server and registry, serves multiple slave EAs, and responds with a live, per‑symbol‑attributed portfolio risk measure. It also explains the non-blocking accept pattern that preserves terminal responsiveness, and includes a dashboard and a test script.

We present an MQL5 script that converts closed trade history into comparable metrics: expectancy in currency, pips, and R-multiples, plus a sample-aware win rate via the Wilson interval. These inputs form a conservative, dimensionless Trade Quality Score. The tool draws a CCanvas panel, prints an Experts-tab report, and supports an hour-based session filter to analyze a defined trading window alongside full-history results.

A robust breakeven implementation for MQL5 is built around live spread sampling and correct pip-to-price conversion by symbol digits. CBreakevenManager moves SL to open_price ± spread ± buffer once a real‑pip activation threshold is reached and prevents duplicate modifications. A demo EA shows the behavioral difference versus a naive breakeven, and a script verifies core calculations.

We build a trade throttle for MQL5 EAs using a token bucket with a priority queue to control order submission rate. Tokens refill at a configurable per‑second rate, allowing short bursts up to capacity and then enforcing sustained throughput. When the bucket is empty, requests are queued and later released by priority with FIFO tiebreaks. This keeps execution within safe limits without discarding valid signals under load.

MQL5 lacks native unit testing, so utility bugs in lot sizing, pip value, and normalization often slip into production. This article presents a zero‑dependency framework built from preprocessor assertion macros, interface‑based suites, and a central runner/formatter. It runs as a script in OnStart, executes deterministic tests, and prints pass/fail summaries to the Experts tab to catch rounding, boundary, and error-handling defects before deployment.

This article presents a circuit breaker for MQL5 that monitors combined daily P&L (realized plus floating) on every tick and compares it to a configured loss limit. On breach, it closes positions, cancels pending orders, and activates a HALTED state that blocks further order submission in the EA until server‑time midnight. The package provides a chart dashboard, a demo Expert Advisor, a verification script, and notes on extending the halt signal across EAs.

This MQL5 engine applies configurable profit ladders in R‑multiples to manage partial closes reliably. It prevents stranded remainders by rounding to lot step, computes close percentages from the original entry volume, and moves the stop to breakeven when configured. A supported filling mode is chosen automatically, and the download includes seven include files, a demo EA, and a verification script.

The article details a master–agent MQL5 framework that mitigates cross-symbol risk concentration. A single Portfolio Controller publishes risk limits and halt flags to Instrument Agents through shared channels and a readiness flag, while agents size orders only within the published budget. It contrasts global variables, named pipes, and files, and clarifies timer intervals and latency so data allocation may be up to one cycle stale without breaking coordination.

The article's system introduces CBasketManager: positions are grouped by a comment‑based basket ID, analyzed as a single snapshot, and controlled with a unified equity stop. CBasketScanner computes aggregate P&L and volume‑weighted pip performance; CBasketStopRegistry triggers coordinated closure on threshold breach; CBasketExecutor adapts to the broker's filling mode. A lightweight dashboard shows live legs, volumes, stops, and distances for faster basket decisions.
