🛠️ Basic Class Construction
→ How to declare a class, use property, define method, and create object instances properly

🔒 Encapsulation & Access Control
→ Use private, protected, and public effectively

🔁 Inheritance
→ Build reusable components and extend functionality the smart way

🧠 Advanced Concepts (Rarely Taught in MQL4):

• 🌀 Polymorphism & virtual functions
• 🧷 Class pointers and memory-safe usage
• 🔍 Getter/Setter patterns
• 🧬 Abstract classes and real-world interface design
• 🧰 Class template (generic-style programming in MQL4!)

MT4 doesn’t support deep Windows control by default —
But MQL4 allows direct access to User32.dll — a powerful Windows API rarely used by beginners.

This module shows you how to leverage it safely and effectively to go beyond normal EA limits.

🔓 You’ll Learn How To:

• 🪟 Open, resize, and manage MT4 chart windows
• 📦 Create custom dialog boxes and alerts
• 🔄 Refresh history tab or simulate user actions
• ⌨️ Trigger keypresses or even simulate virtual ticks

The tools are already there.
We’ll show you how to use them like a pro.

Writing code is the easy part.
Debugging and fixing errors? That’s the real challenge.

In this module, you'll master the 3 critical types of errors every MQL4 developer faces:

🧠 What You'll Learn:

• 📌 Syntax Errors — Catch and fix issues before compile time
• 🧭 Logic Errors — Find hidden bugs that break your EA silently
• 🐢 Performance Errors — Identify slow loops and memory traps
• 🧩 OrderSend() Error Mastery — Understand every return code and how to handle each scenario
• 🔍 Pro Debug Techniques — Trace, log, and isolate bugs like a professional
