# 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**](https://www.metatrader5.com/en/metaeditor/help/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.
