Our MQL5 implementation follows a modern, object-oriented design pattern to ensure stability, reusability, and maintainability. Our MQL5 implementation follows a modern, object-oriented design pattern to ensure stability, reusability, and maintainability.
* **Modular Calculator Engine (`Aroon_Calculator.mqh`):** * **Modular Calculator Engine (`Aroon_Calculator.mqh`):**
All core calculation logic is encapsulated within a reusable include file. This separates the mathematical complexity from the indicator's user interface and buffer management. The logic cleanly implements the "sliding window" search for highs and lows. All core calculation logic is encapsulated within a reusable include file. This separates the mathematical complexity from the indicator's user interface and buffer management.
* **Optimized Incremental Calculation (O(1)):**
Unlike basic implementations that recalculate the entire history on every tick, this indicator employs an intelligent incremental algorithm.
* **State Tracking:** It utilizes `prev_calculated` to process only new bars.
* **Persistent Buffers:** Internal buffers persist their state between ticks, ensuring seamless updates without full recalculation.
* **Object-Oriented Design (Inheritance):** * **Object-Oriented Design (Inheritance):**
* A base class, `CAroonCalculator`, handles the entire shared calculation logic. * A base class, `CAroonCalculator`, handles the entire shared calculation logic.
* A derived class, `CAroonCalculator_HA`, inherits from the base class and **overrides** only one specific function: `PrepareSourceData`. Its sole responsibility is to calculate and provide Heikin Ashi high/low data to the base class's calculation engine, which then proceeds without needing to know the source of the data. This is a clean and efficient use of polymorphism. * A derived class, `CAroonCalculator_HA`, inherits from the base class and **overrides** only one specific function: `PrepareSourceData`. Its sole responsibility is to calculate and provide Heikin Ashi high/low data to the base class's calculation engine.
* **Simplified Main Indicator (`Aroon_Pro.mq5`):**
The main indicator file is extremely clean. Its primary roles are:
1. Handling user inputs (`input` variables).
2. Setting fixed window boundaries (`#property indicator_minimum 0`, `#property indicator_maximum 100`) for correct visualization.
3. Instantiating the correct calculator object (`CAroonCalculator` or `CAroonCalculator_HA`) in `OnInit()`.
4. Delegating the entire calculation process to the calculator object with a single call in `OnCalculate()`.
* **Stability via Full Recalculation:** We use a full recalculation on every tick. For a state-dependent indicator like Aroon, this "brute-force" approach is the most robust method, ensuring perfect synchronization with the price data at all times.
