Lee De Tai

I write MetaTrader Expert Advisors and indicators in native MQL4/MQL5 — no DLLs, no decompiling, no black boxes.

How I work: I read your specification first and come back with the questions that actually change the code — how the stop loss is defined, where the session boundary sits, what exactly counts as a confirmed signal — and then implement what is written. You get commented source, the compiled file, inputs named the way your document names them, and a Strategy Tester run on real ticks so you can watch the logic do what the spec says.

What I do not do is promise that a strategy will be profitable. I implement your rules exactly; the market decides the rest. Jobs where "done" means "the results look good" are not ones I take on, because neither of us can verify them.

Typical work: new EAs from a written specification, debugging and cleaning up existing EAs, turning indicator logic into automated entries, risk and money-management blocks, trade panels and utilities. MT4 and MT5, forex, metals and indices.

Anything that does not match the agreed specification gets fixed free of charge after delivery.

New to MQL5 Freelance in 2026 — my quotes for the first projects are priced accordingly. I answer questions in the order discussion quickly; if something in your spec is unclear, you will hear about it before I start, not after.
