## 3. MQL5 Implementation Details
* **Modular Calculation Engine (`UltimateOscillator_Calculator.mqh`):** The entire calculation logic is encapsulated within a reusable include file, separating the mathematical complexity from the user interface.
Our MQL5 implementation follows a highly modular, component-based design to ensure accuracy, reusability, and maintainability.
* **Object-Oriented Design (Inheritance):** A `CUltimateOscillatorCalculator` base class and a `CUltimateOscillatorCalculator_HA` derived class are used to cleanly separate the logic for standard and Heikin Ashi price sources.
* **Modular Calculation Engine (`UltimateOscillator_Calculator.mqh`):**
The entire calculation logic is encapsulated within a reusable include file.
* **Composition:** The calculator internally uses our universal `MovingAverage_Engine.mqh` to handle the smoothing of the Signal Line. This allows for advanced smoothing types (like DEMA or TEMA) beyond the standard SMA.
* **Optional Signal Line:** The indicator is enhanced with a user-configurable moving average signal line. A `Display Mode` input allows the user to toggle the visibility of this line.
* **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.
* **Sliding Window:** The summation of Buying Pressure and True Range is handled by an efficient sliding window logic (`sum += new_value; sum -= old_value;`), which is significantly faster than recalculating the sum on every bar.
* **Stability and Efficiency:** We employ a full recalculation within `OnCalculate` for maximum stability. The summation of Buying Pressure and True Range is handled by an efficient **sliding window sum** technique (`sum += new_value; sum -= old_value;`), which is significantly faster than recalculating the sum on every bar.
* **Object-Oriented Design:**
* A `CUltimateOscillatorCalculator` base class handles the core UO algorithm.
* A derived class, `CUltimateOscillatorCalculator_HA`, inherits from the base class and overrides the data preparation step to use Heikin Ashi prices.
