## 3. MQL5 Implementation Details
* **Modular and Composite Design:** The core logic is encapsulated in the `Stochastic_CMO_Slow_Calculator.mqh`. This calculator uses a composition-based design: it **contains an instance** of our robust `CCMOCalculator` to generate the base CMO data. This ensures mathematical consistency and leverages our modular design principles.
Our MQL5 implementation follows a modern, component-based, object-oriented design.
* **Reusable Components:** The calculator efficiently reuses our universal `CalculateMA` helper function to apply the selected moving average types for the %K and %D line smoothing.
* **Full Engine Integration:**
The calculator (`Stochastic_CMO_Slow_Calculator.mqh`) orchestrates three powerful engines:
1. **CMO Engine:** It reuses the `CMO_Calculator.mqh` to compute the base Chande Momentum Oscillator.
2. **Slowing Engine:** It uses the `MovingAverage_Engine.mqh` to smooth the Raw %K.
3. **Signal Engine:** It uses another `MovingAverage_Engine.mqh` instance to calculate the %D line.
This ensures mathematical consistency and allows for advanced smoothing types (like DEMA or TEMA).
* **Object-Oriented Design (Inheritance):** The standard `_HA` derived class architecture is used to seamlessly support calculations on Heikin Ashi price data.
* **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 (CMO, Raw %K) persist their state between ticks.
* **Robust Offset Handling:** The engine correctly handles the initialization periods of the chained calculations.
* **Object-Oriented Logic:**
* The Heikin Ashi version (`CStochasticCMOSlowCalculator_HA`) is achieved simply by instructing the main calculator to instantiate the Heikin Ashi version of the CMO module.
