About This Tool

The tool offers an online MQL5 development environment that supports Expert Advisors, indicators, and scripts. It validates syntax, compiles code, and runs backtests against historical data to produce performance metrics. This is intended for traders and developers building automated strategies.
Conceptually, users supply MQL5 code, select a project type, and configure backtest parameters. The tool parses the code, ensures compliance with MQL5 standards, executes the compilation, and, when requested, runs a backtest over chosen symbols and timeframes. Outputs include profit, drawdown, win rate, and equity curves.
Value and differentiation: integrated backtesting and optimization within a single online workspace; support for multiple project types; robust error reporting and edge-case handling; exportable results for reporting; designed for speed and reproducibility without needing local MT5 installation.

How to Use

  1. Provide inputs: choose project_type (ExpertAdvisor, Indicator, Script);
  2. Paste or import your MQL5 code;
  3. Configure backtest parameters: symbol, timeframe, initial_balance, date range;
  4. Run compile and backtest;
  5. Review results and export reports as needed.

Frequently Asked Questions

Find Quick Answers

Can I run live trading from this editor?
No. The tool is designed for development, backtesting, and optimization in a sandbox environment. It provides simulated results based on historical data and does not connect to live markets or execute real trades.
What MQL5 features are supported?
Supports standard MQL5 syntax for Expert Advisors, Indicators, and Scripts, including common event handlers and functions. Advanced libraries and proprietary APIs may be limited depending on the sandbox configuration.
How is backtesting data sourced?
Backtests use integrated historical data packs for selected symbols and timeframes. If data is missing or incomplete for a given period, the tool reports gaps and may skip that segment of the test.
Can I export results?
Yes. Backtest results, trade lists, and performance metrics can be exported as CSV or JSON for reporting and further analysis.
