Don't trust AI-written EAs. Prove them.
Describe your strategy in plain English. MQL Studio writes the MetaTrader EA, compiles it, and runs a real MetaTrader 5 backtest — so you see actual results before you trust it, not just code that looks right. You keep your IP and download the full source. Prefer it done for you? Our team still builds custom EAs on request.
MQL Studio — your EA workbench
A self-serve studio: chat to build, backtest on real data, and iterate — no coding, no waiting on a developer.

📊 Real backtests
One click runs your EA in the genuine MetaTrader 5 Strategy Tester — net P/L, win rate, profit factor, drawdown, trade count, full report.
🕓 Version history

🔒 Private to you
Your strategies and results live in your account only — never shared, never resold. You own the source.

How MQL Studio works
From idea to a backtested EA in four steps — right in your browser.
Describe your strategy
Tell Studio your symbol, timeframe, entry/exit logic and SL/TP in plain English. Refine it in chat like any AI assistant.
Studio writes the EA
It generates a clean MQL5 Expert Advisor from your description and saves it as a version you can revisit.
Backtest on real data
One click runs it in the genuine MetaTrader 5 Strategy Tester. You watch the queue and get net P/L, win rate, profit factor, drawdown and trade count.
Iterate & own it
Tweak the rules, re-backtest, compare versions, and download the full source. It's yours.
Real results on your own strategy
Every build is run through the genuine MetaTrader 5 Strategy Tester on your chosen symbol and period. You see the actual report — net profit, win rate, profit factor, maximum drawdown and trade count — on your strategy, not a sample. Past performance never guarantees future results.
Frequently asked questions
What is an MQL5 Expert Advisor?
An MQL5 Expert Advisor (EA) is an automated trading program written in the MQL5 language that runs inside MetaTrader 5 and executes a strategy — entries, exits, stop-loss and take-profit — automatically. MQL4 is the equivalent for MetaTrader 4.
Do you provide backtest results before delivery?
Yes — every EA is run through the MetaTrader Strategy Tester and delivered with a report showing net profit, win rate, profit factor, maximum drawdown and trade count.
Do I get the source code?
Yes. You receive the full .mq4/.mq5 source, the compiled EA, and the tester report, so you own and can modify the strategy.
Can you convert a Pine Script strategy?
Yes, as long as the entry and exit rules are clearly defined. We reimplement the logic natively in MQL4 or MQL5.
