## MQL5 Indicator & Script Collection: Comprehensive Catalogue

### Introduction

This document provides a comprehensive overview of our custom-developed MQL5 indicator collection. Every tool in this library was built following three core principles:

1. **Stability Over Premature Optimization:** All indicators utilize a "full recalculation" model, ensuring robust and glitch-free performance. Recursive calculations are carefully and manually initialized.
2. **Pragmatic Modularity:** Complex logic is encapsulated into centralized, object-oriented calculator engines (`_Calculator.mqh` or `_Engine.mqh`), promoting clean, maintainable, and reusable code across indicator families.
3. **Definition-True Implementation:** Our indicators are implemented to match the original author's mathematical formula as closely as possible, aligning with the global standard used on professional platforms.

A key feature of our "Pro" series is the unification of standard and Heikin Ashi calculations into a single, flexible indicator, allowing the user to choose the desired data source via input parameters.
