About This Tool

The tool offers a browser-based MQL5 code editor and project workspace for developers and traders building Expert Advisors, indicators, and scripts for MetaTrader 5. It supports multiple source files (.mq5 and .mqh) and provides language-specific syntax highlighting and context-aware hints to accelerate coding. A sandbox build engine validates syntax and performs basic runtime checks, returning precise compiler diagnostics with line references.
Users can create or upload projects, organize files, reference libraries, and compile to verify correctness before testing. The online environment enables quick onboarding for new team members and brokers seeking reproducible workflows.
Backtest scaffolds and sample data help evaluate strategy behavior without local installations, while sharing and versioning enable collaboration and knowledge transfer. The combination of accessibility, language-focused tooling, and project-centric collaboration differentiates this tool from generic code editors.
Project management, syntax highlighting, error diagnostics, code snippets for MQL5 patterns, auto-completion for built-in functions, include resolution, and import/export support speed up development and testing for individual developers and teams.

How to Use

Provide inputs by creating or uploading MQL5 source files (.mq5) and headers (.mqh) and setting project metadata.
Choose target type (EA, Indicator, Script) and configure optional backtest templates.
Run compile to view diagnostics; fix syntax or dependency issues based on line references.
Iterate edits with code suggestions and snippets; run backtests with built-in test data when needed.
Save, export, or share the project with teammates; manage versions and dependencies.
