About 4x Engineer
4x Engineer is a team of trading software engineers. We work with traders, fund managers, signal providers and trading businesses to automate strategies across Forex, crypto and stock markets.
Every project starts with your rules and ends with software you can rely on: written cleanly, tested before it touches a live account and supported after delivery. Alongside custom development we offer MQL Lock, a licensing service that protects Expert Advisors from unauthorized use.
