My name is Park Sung Chan, a developer specializing in MetaTrader 5 algorithmic trading systems.
I design and research long-term, reliable automated trading models based on the structural characteristics and statistical patterns of financial markets.
Rather than building simple trading strategies, I focus on interpreting the market from multiple perspectives and developing high-level algorithmic frameworks that can adapt and evolve over time.
🔥 Introduction to the NEXA EA Project (Strategy Ecosystem)
The NEXA EA Project is an expandable strategy-development program built upon my research philosophy.
Its goal is not to create a single EA, but to establish a sustainable and stable automated trading ecosystem.
Each strategy is designed from various market perspectives—trend, swing, volume, volatility, and more—and developed through long-term backtesting and structural validation processes.
🔧 Expertise
• Structural market analysis based on Trend / Swing / Volatility / Breakout models
• Algorithm design focused on reproducibility with 3–10 year long-term backtests
• Drawdown reduction and risk-structure optimization
• Multi-timeframe system architecture with refined entry logic
• Technical support for users across 11 countries worldwide
In addition, I continuously conduct internal research projects to build more advanced automated trading frameworks, strengthening the reliability and structural integrity of future strategies.
(Core engines and internal technologies are not publicly disclosed.)
🎯 Development Philosophy
For me, an EA is not just a “trading script,” but a structural model that continually adapts to market changes.
I follow four essential principles:
✔ Stability
A robust framework that remains steady despite market fluctuations.
✔ Clarity
Clear, intuitive, and elegant algorithmic design.
✔ Consistency
Performance that can be reproduced and maintained over long periods.
✔ Evolution
Continuous research and improvement to evolve the strategy.
This philosophy is the foundation of the entire NEXA EA lineup, where every system is designed with a focus on long-term survivability rather than short-term results.
🌍 NEXA EA — Long-Term Strategy Ecosystem
NEXA EA is a long-term algorithmic ecosystem that grows and improves over time.
Each EA functions as an independent strategy, while simultaneously forming part of a broader portfolio structure—providing users with a stable and diversified automated trading environment.
🤝 Commitment to Users
• Clear and transparent explanation of all strategy logic
• Systems designed to perform reliably under diverse market conditions
• Continuous updates and trustworthy technical support
I am committed to ensuring that your automated trading experience becomes more stable, reliable, and consistent.
Thank you.
