* **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. * **Flexible Signal Line Calculation:** The calculator dynamically instantiates either a third `Laguerre_Engine` or a `MovingAverage_Engine` for the signal line.
