Fredrick Chege Muiruri / プロファイル

I am an expert MQL5 developer specializing in the design, development, and optimization of advanced Expert Advisors and custom indicators for MetaTrader 5. I work with traders, funds, and trading businesses to convert complex trading concepts into reliable, scalable, and production-ready automated trading systems.

My development approach is engineering-driven and focused on real-market performance. I build EAs with structured architecture, modular logic, and strict execution control to ensure stability under varying market conditions, including high volatility, spread changes, and execution delays. All systems are designed with robust risk and money management at their core, not as an afterthought.

I have deep experience implementing advanced trade logic, including dynamic position sizing, partial closes, break-even and trailing mechanisms, session-based trading, news filters, and complex order management. I also develop custom indicators from raw market data, including multi-timeframe calculations, custom buffers, signal filtering, and performance-optimized plotting.

My work includes optimization and backtesting using high-quality historical data, parameter validation, and logic verification to ensure strategies behave exactly as intended. I focus on clean, readable, and well-documented MQL5 code that is easy to maintain, extend, and audit. Performance, execution accuracy, and error handling are key priorities in every project.

I maintain clear and professional communication throughout the project lifecycle, provide realistic technical feedback on strategy feasibility, and offer post-delivery support to ensure smooth deployment and long-term usability. My objective is to deliver not just working code, but a dependable automated trading solution built to professional standards.
