EA Modification & Enhancement
Upgrade and improve your existing Expert Advisors with new features, bug fixes, and performance enhancements. Add indicators, improve risk management, or modernize old EAs.
About This Service
Already have an EA but need it improved or updated? Our EA modification and enhancement service breathes new life into existing Expert Advisors. Whether you need bug fixes, new indicators added, improved risk management, or complete modernization of old code, our experienced MQL developers can help. We work with EAs written by others, protected code (when possible), legacy MT4 EAs that need MT5 conversion, and outdated systems requiring modern features. Common enhancements include adding trailing stops, breakeven logic, time filters, news avoidance, partial close functions, multi-timeframe confirmations, dashboard panels, and remote monitoring. We also optimize slow or inefficient code, fix compilation errors in outdated EAs, and add protective features against broker manipulation. Perfect for traders who have EAs that almost work but need that final touch to become truly profitable and reliable.

Frequently Asked Questions
Can you modify an EA if I only have the .ex4 file (no source code)?▼
In most cases, yes. We can decompile .ex4 files and modify the logic, though this takes longer. However, heavily protected EAs may be impossible to modify without source code.
How much does it cost to add features to an existing EA?▼
Simple additions (like a new indicator or time filter) start at $100-200. Complex enhancements (like rebuilding the risk management system) range $300-800.
My EA stopped working after a MetaTrader update. Can you fix it?▼
Absolutely! This is a common issue. MT4 and MT5 updates sometimes break old code. We'll modernize the code to work with current MetaTrader builds.
Can you make my EA work on MT5 instead of MT4?▼
Yes! MT4 to MT5 migration is one of our core services. We'll convert the EA to MQL5 while maintaining all functionality and adding MT5-specific improvements.
What if I don't know exactly what changes I need?▼
That's fine! During our consultation, we'll review your EA's current performance and recommend specific improvements to increase profitability and reduce risk.
