The AI workspace for
MetaTrader 5 developers.
Paste your MQ4 or MQ5 code. Ask the AI to explain, fix, optimize, add trailing stops, or convert MQ4 → MQ5. Export compile-safe files ready for MetaEditor — no more guessing, no more hallucinated functions.

}Add ATR-based trailing stop and risk-percent sizing.
Updated OnTick() with CalcLotByRisk and a 2× ATR trailing stop. Diff ready to apply.
Built specifically for MQL.
Generic code assistants hallucinate MQL functions. Dungeon Bot Builder is tuned for MetaTrader: it knows CTrade, ENUM_TIMEFRAMES, magic numbers, freeze levels, and synthetic-index quirks.
Monaco editor, MQL-aware
VSCode-grade editor with syntax highlighting and an AI side chat that sees your file.
Compile-safe AI
Template-grounded responses use CTrade, NormalizeDouble, magic numbers and freeze levels correctly.
MQ4 → MQ5 conversion
One-click migration that rewrites OrderSend logic into the modern Trade library.
Synthetic index aware
Knows V75/V100/Boom/Crash quirks: tick-driven, no swap, spike handling.
Risk & trailing modules
Drop in risk-percent sizing, ATR trailing stops and break-even with one prompt.
Export real .mq5 files
Download your file ready to drop into MetaEditor on Windows for compilation.
From idea to .mq5 in three steps
