Send us your trading strategy or your existing EA. We reply with questions or a quote, code or optimize it, and hand you a tested EA together with its MT5 Strategy Tester reports.
Tell us where you are. The quote says exactly what is included before any work starts.
You describe the rules: entries, exits, indicators, money management. We turn them into an MQL5 Expert Advisor for MT5, then backtest it on real ticks so you see how the rules really behaved.
Your EA works, but not well enough. We search its settings on real-tick history, check the result on periods it was not tuned on and through crisis windows, and tell you what is robust and what is luck.
An EA that throws errors, misses trades, needs a new feature, or only exists for MT4. We fix it, add what you need, or rewrite it in MQL5 for MetaTrader 5.
The form below or Telegram. Two minutes is enough.
Usually within 24 hours: scope, price and timeline.
You get progress updates on Telegram.
Real-tick MT5 backtests, every period shown.
We help you get it running on your MT5.
The tools and checks we use on every client project.
MT5 Strategy Tester on real ticks, on tick history going back to 2010 as well as your broker's own data.
A farm of MT5 terminals runs optimizations side by side, so a full search finishes in hours instead of weeks.
Settings are checked on periods they were not tuned on, walk-forward, and through crisis windows such as the 2020 crash.
You see every period we tested, the bad ones too. If a strategy does not hold up, we tell you before you trade it.
Yes. Your rules, code and files are used only for your project. We never resell or publish a client's strategy.
It depends on the size of the job. A simple EA or a fix can take a few days; a full optimization takes longer. Your quote states the timeline.
By default you receive the compiled EA (.ex5). If you need the source code (.mq5), say so - it is agreed in the quote.
No one honestly can. We build and test exactly what was agreed and show you the real backtest results, good and bad, so you can decide.
With USDT or PayPal. The payment terms are written in your quote before any work starts.
Yes. Choose "Fix or convert" in the form and we will rewrite it in MQL5 for MetaTrader 5.
The quote is free. We read every request personally and usually reply within 24 hours.
We usually reply within 24 hours by email (check your spam folder) or on Telegram. Send any files to @Thangforex and mention your request number.
Message on TelegramI’m Ho Tuan Thang — a solo quant who spent ten years in a small room in Chicago, building EAs no one asked for, blowing up demo accounts so live ones wouldn’t, and waiting for the technology to catch up to the idea. When large language models finally landed, the door opened. This is the short version of how we got here, and why I’m now spending most of my days helping other traders walk through it.
“I never wanted to sell signals. I wanted to build a co-pilot — something a serious trader could actually trust at 2 a.m. when the chart goes sideways. That’s the only thing I work on now.”
— Ho Tuan Thang · Founder, eatrading.ai
Started trading stocks and forex out of curiosity. Got humbled fast. Spent two years studying price action, risk management and the work of people like Van Tharp and Andreas Clenow — convinced the edge had to be systematic, not discretionary.
Learned MQL5 the hard way. Shipped a handful of rule-based EAs for friends, then a small client base. Every system traded my own money first. Lesson burned in: backtests lie, slippage is real, and an EA that needs a perfect market dies in a normal week.
When GPT-4 and Claude opened up reasoning at machine speed, I rebuilt the engine from scratch. Started wiring multi-model ensembles into MT5 — real models, real keys, real accounts. Six iterations later, the Quant AI Agents framework was born.
Today I split my week between shipping product and walking traders — in Vietnam, the Philippines, India, the EU and the US — through the messy migration from indicator EAs to AI-native systems. The goal is unchanged: arm the independent trader with the same firepower a hedge-fund desk takes for granted.
