Drag widgets onto the chart.
Get production MQL5.
Pick from an Equity bar, Signal Strength meter, Spread/Latency gauge and Open Positions table — or describe your own. The builder emits clean OBJ_RECTANGLE_LABEL code, wires DashInit/Update/Deinit into your event handlers, and cleans up every object on detach.
- Auto-detects existing dashboards in your saved bots
- Magic-number-prefixed objects — multi-chart safe
- EventSetTimer(1) for tick-less refresh
- Round-trip edit: change a widget, re-inject, recompile
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.
Auto self-review pass
Every generated EA is re-compiled mentally by a 2nd model that fixes compile errors, missing SL/TP, and risk gaps before it hits your editor.
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 management baked in
Risk-% sizing, ATR stops + trailing, break-even at +1R, daily-loss circuit breaker — defaults on every bot.
Visual dashboard builder
Drag widgets onto a faux chart, regenerate MQL5 object code, or auto-detect dashboards in saved bots.
Backtest-ready defaults
Grouped inputs, magic-number scoping, broker-suffix-safe symbol handling — pass through Strategy Tester cleanly.
AI dashboard prompt
Describe a HUD in English — “equity bar + daily P/L with red glow if loss > 2%” — get OBJ_RECTANGLE_LABEL code.
Export real .mq5 files
Download your file ready to drop into MetaEditor on Windows for compilation.
From idea to .mq5 in three steps
- 01Describe your strategy
“RSI + EMA crossover on V75 with 1% risk, ATR trailing.” Or paste an existing MQ4/MQ5 file.
- 02AI builds & self-reviews
Generates the EA, then a 2nd pass hardens compile errors, SL/TP, risk caps and event cleanup.
- 03Export & compile
Download the .mq5, drop it in MetaEditor, attach to a chart. Zero red squiggles.
Trusted by MT5 traders & devs.
“First AI that actually knows ENUM_BASE_CORNER. My V75 scalper compiled clean on the first export.”
“The daily-loss breaker saved a challenge. I just described the rule, the AI baked it into OnTick.”
“Dashboard builder is genius. Drag four widgets, hit insert, done. No more wrestling with OBJ_LABEL.”
