* **Modular "Family" Architecture:** The core Laguerre filter calculation is encapsulated in a central `Laguerre_Engine.mqh` file. This engine is a **stateful class** that correctly maintains the state of its internal recursive components, ensuring a stable and accurate foundation. The `Laguerre_RSI_Calculator.mqh` is a thin adapter that uses this stable engine to generate the RSI. * **Modular "Family" Architecture:** The core Laguerre filter calculation is encapsulated in a central `Laguerre_Engine.mqh` file.

* **Heikin Ashi Integration:** An inherited `CLaguerreEngine_HA` class allows the calculation to be performed seamlessly on smoothed Heikin Ashi data.
* **Stability via Full Recalculation:** We employ a full recalculation within `OnCalculate` for maximum stability. * **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 buffers (`m_L0`...`m_L3`) persist their state between ticks, allowing the recursive Laguerre algorithm to continue seamlessly from the last known value.
* This results in **O(1) complexity** per tick, ensuring instant updates and zero lag, even on charts with extensive history.
* **Heikin Ashi Integration:** An inherited `CLaguerreEngine_HA` class allows the calculation to be performed seamlessly on smoothed Heikin Ashi data, leveraging the same optimized engine.
* **Value Clamping:** The final calculated value is mathematically clamped to the 0-100 range. * **Value Clamping:** The final calculated value is mathematically clamped to the 0-100 range.
