Institutional-Grade Multi-Currency Portfolio Engine in MQL5 (Part 2): Instrument Universe Management and Symbol Metadata
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.
Surrogate Data Testing: A Null Model for Any Statistic, and Why Shuffling Bars Is Not One
We implement surrogate testing for indicators in MQL5: generate synthetic series that match your data's distribution and spectrum, score any statistic, and locate the observation within its null distribution. The library provides four null models, an FFT that handles arbitrary lengths, and a plug‑in interface for custom measures. An indicator visualizes the statistical alongside its chance band for direct interpretation.
How to Detect and Normalize Chart Objects in MQL5 (Part 6): Manipulating Chart Objects with MetaTrader 5 Agentic AI Assistant
This article demonstrates how natural-language prompts generate MQL5 producer programs that place native chart objects, and how a deterministic Expert Advisor (AIObjectTrader) reads them through a structured naming and geometry contract. We compare indicator and script routes, using three cases: horizontal resistance, a persistent Andrews' Pitchfork, and Fibonacci Time Zones. Readers gain a reproducible workflow to connect AI-built objects to TOUCH/BREAK/ZONE evaluation and optional execution.
Variational Mode Decomposition: Building the Solver, and Measuring What Hindsight Buys
A from‑scratch VMD library for MetaTrader 5: radix‑2 transform, ADMM updates, mirrored windows, and a result type that reports solve quality and mode separation. We verify the solver to full double precision against a reference and test causality by sabotage. The article quantifies repaint from batch versus causal runs and compares it to volatility‑matched random walks. You get a causal indicator, usable diagnostics, and settings that avoid common pitfalls.
Beyond Clone and Commit: The Advanced Side of MQL5 Algo Forge
We map the parts of Algo Forge that impact day-to-day MQL5 work: opening repos in MetaEditor, README translation, Units, branch/tag protection, browser patching, packages, and CI on a Windows host. The article shows exact settings, required runner labels, and how to gate merges on builds. You leave with reproducible steps to protect code, automate compiles, and ship artifacts.
