* **Self-Contained Calculator (`MAMA_Calculator.mqh`):** The entire complex, multi-stage, and highly state-dependent calculation is encapsulated within a dedicated, reusable calculator class. * **Self-Contained Calculator (`MAMA_Calculator.mqh`):** The entire complex, multi-stage, and highly state-dependent calculation is encapsulated within a dedicated, reusable calculator class.
* **Heikin Ashi Integration:** An inherited `_HA` class allows the calculation to be performed seamlessly on smoothed Heikin Ashi data, leveraging our optimized `HeikinAshi_Tools` library. * **Optimized Incremental Calculation:**
* **Stability via Full Recalculation:** The MAMA algorithm is one of the most state-dependent filters in technical analysis. To ensure absolute stability and prevent desynchronization errors (especially with the phase measurement), the indicator employs a **full recalculation** on every `OnCalculate` call. This is the only robust method for this type of complex DSP filter. 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 for the Homodyne Discriminator (`m_I1_buf`, `m_Q1_buf`, etc.) and the phase measurement persist their state between ticks. This allows the complex DSP pipeline to continue seamlessly from the last known values without re-processing the entire history.
* 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 `_HA` class allows the calculation to be performed seamlessly on smoothed Heikin Ashi data, leveraging the same optimized engine.
