This separates the mathematical complexity from the indicator's user interface and buffer management. +* **Optimized Incremental Calculation:** + Unlike basic implementations that recalculate the entire history on every tick, this indicator employs an intelligent incremental algorithm. + * It utilizes the `prev_calculated` state to determine the exact starting point for updates. + * **Persistent State:** The internal price buffer (`m_price`) persists its state between ticks. This allows the calculation to efficiently access historical price data for the Efficiency Ratio without re-copying the entire series. + * This results in **O(1) complexity** per tick, ensuring instant updates and zero lag, even on charts with extensive history. + * **Object-Oriented Design (Inheritance):** * A base class, `CAMACalculator`, handles the core AMA algorithm, including the ER, SSC, and the final recursive calculation. * A derived class, `CAMACalculator_HA`, inherits from the base class and **overrides** only one specific function: the price series preparation. Its sole responsibility is to calculate Heikin Ashi candles and provide the selected HA price to the base class's AMA algorithm. This is a clean and efficient use of polymorphism. -* **Simplified Main Indicator (`AMA_Pro.mq5`):** - The main indicator file is now extremely clean. Its primary roles are: - 1. Handling user inputs (`input` variables). - 2. Instantiating the correct calculator object (`CAMACalculator` or `CAMACalculator_HA`) in `OnInit()` based on the user's choice. - 3. 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 recursive indicator like AMA, this "brute-force" approach is the most robust method, eliminating potential errors from `prev_calculated` logic. The recursive calculation is carefully initialized with the current price to provide a stable starting point. - ## 4.
