Our MQL5 implementation follows a modern, component-based, object-oriented design. Our MQL5 implementation follows a modern, component-based, object-oriented design.
* **Component-Based Design:** The StochRSI calculator (`StochRSI_Fast_Calculator.mqh`) **reuses** our existing, standalone `RSI_Pro_Calculator.mqh` module. This eliminates code duplication and ensures consistency. * **Component-Based Design (Composition):**
The StochRSI calculator (`StochRSI_Fast_Calculator.mqh`) is a powerful orchestrator that reuses two of our core engines:
1. **RSI Engine:** It delegates the RSI calculation to the robust `RSI_Pro_Calculator.mqh`.
2. **MA Engine:** It delegates the %D signal line smoothing to the universal `MovingAverage_Engine.mqh`.
This ensures mathematical consistency across the entire suite and eliminates code duplication.
* **Optimized Incremental Calculation:** * **Advanced Smoothing Options:**
Thanks to the integration with the `MovingAverage_Engine`, the %D signal line supports **seven** different smoothing methods (SMA, EMA, SMMA, LWMA, TMA, DEMA, TEMA).
* **Optimized Incremental Calculation (O(1)):**
Unlike basic implementations that recalculate the entire history on every tick, this indicator employs an intelligent incremental algorithm. 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. * **State Tracking:** It utilizes `prev_calculated` to process only new bars.
* **Persistent State:** The internal buffers (like `m_rsi_buffer`) persist their state between ticks. This allows the calculation to efficiently access historical RSI data for the High/Low range search without re-copying or re-calculating the entire series. * **Persistent Buffers:** Internal buffers persist their state between ticks.
* This results in **O(1) complexity** per tick, ensuring instant updates and zero lag, even on charts with extensive history. * **Robust Offset Handling:** The engine correctly handles the initialization periods of the chained calculations (RSI -> StochRSI -> %D), ensuring that each step starts only when valid data is available. This prevents artifacts and "INF" errors at the beginning of the chart.
* **Object-Oriented Logic:** * **Object-Oriented Logic:**
* The `CStochRSI_Fast_Calculator` contains a pointer to an `CRSIProCalculator` object. * The Heikin Ashi version (`CStochRSI_Fast_Calculator_HA`) is achieved simply by instructing the main calculator to instantiate the Heikin Ashi version of the RSI module.
* The Heikin Ashi version (`CStochRSI_Fast_Calculator_HA`) is achieved simply by instructing the main calculator to instantiate the Heikin Ashi version of the RSI module (`CRSIProCalculator_HA`).
* **Full MA Type Support:** The calculator contains a complete, robust implementation for all standard MQL5 MA types (SMA, EMA, SMMA, LWMA) for the "%D" signal line smoothing.
