Looi Kah Fung

I'm an independent algorithmic trading systems developer specializing in MetaTrader 5 Expert Advisor design, based in Malaysia. Under the A1 brand, I build institutional-style automated trading systems from the ground up — strategy logic, risk management, licensing infrastructure, and dashboard interfaces — as a single developer rather than a team, which means every line of every product is built, tested, and supported directly by me.

My current lineup spans multi-symbol portfolio EAs, pivot-based grid systems, and near-close strategy portfolios, each built on a consistent architecture with per-symbol risk controls, persistent state recovery, and real-time performance dashboards. I've also engineered a custom licensing and protection system used across all my products, and built standalone risk-guardrail tools (news/event blackout protection) to help protect live accounts during high-impact market events.

I work directly with clients — no resellers, no marketplace middlemen — which means direct support and continuous refinement based on real usage.
