MQL5 Programming for Traders

Examples from the book "MQL5 Programming for Traders" - author Stanislav Korotky

The repository is organized into the standard MQL5/ directory structure (Scripts / Experts / Indicators / Include / Files, etc.) and grouped by book sections (p1 … p7) to make it easy to:

• open the project in MetaEditor,
• compile examples as you progress through the book,
• run them in MetaTrader 5 and in the Strategy Tester.
