Trading bots, built and tested properly.

What I build

Built for live accounts.

Most bots fail on the details: broker symbol suffixes, stop levels, spread spikes, daylight-saving session times, RPC limits, slippage. Those details are the job.

01 / MT5

Expert Advisors and indicators

New EAs from your rules, or fixes and upgrades to one you already have.

Questions

Straight answers.

Can you build me a profitable bot?

Nobody honest can promise that. I build exactly what you specify, test it properly and tell you what the numbers show. If a strategy fails testing, you'll know before you pay for more.

Do I get the source code?

Yes. You get the full source code, not just a compiled file.

What do you need from me?

Your rules in plain language (or the existing EA or bot), the platform or chain, your broker or exchange, and a deadline. Screenshots of your setups help.

How do payments work?

A fixed price agreed before work starts. 50% to begin, 50% on delivery, in USDC or USDT. Other methods on request.

Send your rules.

Rough is fine: a list of entry and exit rules, a screenshot of a setup, or the EA or bot you want changed.

  • Fixed quote within 24 hours
  • Source code included
  • Honest test results
