 This indicator visually represents the convergence and divergence of momentum. The height and depth of the histogram bars provide an immediate sense of momentum acceleration and deceleration.
 
-It is designed as a **companion indicator** to be overlaid in the same window as the `MACD_Laguerre_Line_Pro`. When their parameters are synchronized, they form a complete, modern, and highly responsive MACD system. The signal line's smoothing method is user-selectable, offering a choice between a **Laguerre filter** or one of the four standard moving average types (SMA, EMA, SMMA, LWMA).

 * **Self-Contained Calculation:** The indicator is fully self-contained. Its engine (`MACD_Laguerre_Histogram_Calculator.mqh`) internally recalculates the entire Laguerre MACD line using the `Laguerre_Engine`. This "shared engine" architecture avoids the instability of `iCustom` calls.

+* **Optimized Incremental Calculation (O(1)):**
     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 Laguerre engines persist their state (`L0`...`L3`) between ticks, allowing the recursive calculation 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.
 
-* **Flexible Signal Line Calculation:** The calculator dynamically instantiates either a third `Laguerre_Engine` or a `MovingAverage_Engine` for the signal line, depending on the user's choice. This ensures that the signal line calculation is also fully optimized and incremental.
