This article introduces a lightweight OS-like helper for MQL5 that streamlines file and path operations using a Python-inspired interface. We implement getcwd, listdir, scandir with DirEntry, remove, rmdir, rename, mkdir, stat, and an os.path subset (exists, isfile, isdir, join, split, pardir). You will learn how to work consistently within the terminal Files/common sandbox and simplify everyday filesystem tasks.
Code and build Python-based trading robots just like MQL5 Expert Advisors (EAs). In this article, we develop a Python-based replica of the MetaTrader 5 Python package, providing methods that closely resemble those of MetaTrader 5 during simulation. This allows us to backtest Python EAs in a simplified environment, using an approach similar to developing and testing Expert Advisors in MQL5.
This article presents reusable MQL5 utilities for managing trailing and break-even stops. It covers fixed-point, moving average, ATR, Parabolic SAR, money-based, and time-periodic trailing, plus break-even by points and by money, with activation thresholds, step logic, reverse-move protection, and broker-level validation. Code examples and Bootstrap classes show how to integrate these helpers into Expert Advisors to standardize position control and reduce duplicate code.

This article presents a unified news model and a set of reusable MQL5 classes for working with the MetaTrader 5 Economic Calendar. You will retrieve, filter, and cache events by time, currency, country, and importance using a single interface across three providers: built-in calendar, CSV, and SQLite. The framework supports export/import, next/previous event lookup, and reliable strategy‑tester backtesting without changing trading logic.
Channel Studio — you draw it, the EA trades it Two tools in one: a full vector markup editor that lives on the chart, and a semi-automatic expert advisor that trades what you have drawn. You do not tune parameters and you do not hand your account to a black box. You mark up the chart exactly the way you already do it by eye, and the EA takes over only the execution: it waits for the touch, opens the trade, trails the stop along your curve and reverses according to a rule you described in
Drawing Studio — a simple tool for drawing vector elements right on your chart, helping you see what the eye alone can't. Trend lines, channels, parabolas, Fibonacci levels and a ruler — everything is drawn on a high-performance canvas with true anti-aliasing, not as standard terminal objects. The result is speed, cleanliness and beauty: thin, smooth lines instead of jagged "staircase" edges, and a chart that never gets cluttered with dozens of objects.

The article builds a reusable validation layer for Expert Advisors in MQL5. It implements lot-size rules and normalization, SL/TP and freeze-level guards, price digit normalization, margin sufficiency checks, unchanged-level filtering on modifications, account order-limit control, new-bar detection, symbol tradability checks, economic-calendar news windows, and session detectors. The result is cleaner code and fewer terminal errors in live trading.
