Everything you need to build, fix and run MetaTrader programs

Build

Describe a trading strategy in your own words, or design it step by step in the Strategy Creator. The Lab asks only what is missing to make the rules exact, shows you a review of what it will build, and builds it after you confirm.

• AI EA builder: Expert Advisors for MT4 or MT5 from a description or a confirmed specification.
• AI indicator builder: custom indicators with buffers, arrows and alerts.
• Large programs are planned module by module first, with the size and price shown before any code is written.

Convert

Move a program between MetaTrader 4 and MetaTrader 5, or between an EA and an indicator, with a report of every difference that matters.

• MT4 → MT5: orders become positions, indicators become handles, and the trading logic is kept.
• MT5 → MT4: positions become orders, with a rule-based port where it is exact.
• Indicator → EA and EA → Indicator: trade an indicator's signals, or draw an EA's entries as arrows.

Fix and change

Upload code with or without MetaEditor errors. The Lab compiles it, finds the cause of each error, fixes it and checks the result again. Changes you describe, such as a break-even, a spread filter or a daily loss limit, are made without touching anything else.

Check and explain

Check my code runs ten checks and issues a verification certificate: compile check with MetaEditor, right platform functions, right kind of program, trading code reached, real-broker issues, inputs, risk protection, the confirmed strategy, safety, and an AI dry run. The same code always gets the same certificate. Explain my code describes any file in plain words.

Monitor live EAs with FXNook Telemetry

Add a small reporting library to your EA in one click, and see what it does in the real market: every rule it checks, every decision, every order, trade and error, with insights and daily summaries. Telemetry only observes; it never trades.

Built to be trusted

• Your code stays yours and is never used to train AI models.
• Every change is a new version; the original is kept.
• Prices in credits are shown before a job starts; failed jobs are not charged.
• Downloads are signed links that expire after 15 minutes.

Questions

Does FXNook AI Code Lab work with MT4 and MT5?

Yes. It reads and writes MQL4 (MetaTrader 4) and MQL5 (MetaTrader 5) code, including the .mqh files a program includes, and converts between them.

Do I need to know how to code?

No. You can describe a strategy in plain words and the Lab asks only for what is missing. Developers can upload their own code and use the Lab to fix, convert, check or change it.

Is the code checked before I download it?

Yes. Every result goes through the Lab's own checks and, when connected, MetaEditor itself. Anything that could not be resolved is listed in the report.
