* **Universal Calculation Engine (`VIDYA_Calculator.mqh`):**
A single, powerful engine file contains all the core calculation logic. This eliminates code duplication and ensures that both `VIDYA_Pro` and `VIDYA_Color_Pro` produce identical average values.
* **Composition with CMO Engine:** The VIDYA calculator does not re-implement the CMO logic. Instead, it internally instantiates our robust `CMO_Calculator` class. This ensures that the momentum measurement is mathematically identical to the standalone CMO indicator.

This ensures that the momentum measurement is mathematically identical to the standalone CMO indicator, while maintaining high performance.
* **Optimized Incremental Calculation:**
* **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 buffers (`m_price`, `m_cmo_buffer`) persist their state between ticks. This allows the recursive VIDYA calculation to continue seamlessly from the last known value without re-processing the entire history.
* This results in **O(1) complexity** per tick, ensuring instant updates and zero lag.
* **State Tracking:** It utilizes `prev_calculated` to process only new bars.
* **Persistent Buffers:** Internal buffers persist their state between ticks.
* **Efficiency:** The recursive VIDYA calculation continues seamlessly from the last known value without re-processing the entire history.
* **Method Overloading:** The `CVIDYACalculator` class features two versions of the `Calculate` method:
1. `Calculate(..., double &vidya_buffer[])`: A version that accepts a single output buffer. This is automatically called by `VIDYA_Pro`.
2. `Calculate(..., double &vidya_up_buffer[], double &vidya_down_buffer[])`: A version that accepts two output buffers. This is automatically called by `VIDYA_Color_Pro`.
1. `Calculate(..., double &vidya_buffer[])`: For `VIDYA_Pro`.
2. `Calculate(..., double &vidya_up_buffer[], double &vidya_down_buffer[])`: For `VIDYA_Color_Pro`.
* **Object-Oriented Design (Inheritance):**
The engine uses a `CVIDYACalculator` base class and a `CVIDYACalculator_HA` derived class. The child class only overrides the `PreparePriceSeries` method to supply Heikin Ashi data, inheriting the entire complex calculation logic from its parent.

## 4. Parameters (`VIDYA_Pro` & `VIDYA_Color_Pro`)
The input parameters are identical for both indicators.
* **CMO Period (`InpPeriodCMO`):** The lookback period for the Chande Momentum Oscillator. Default is `9`.
* **EMA Period (`InpPeriodEMA`):** The base period for the EMA smoothing. Default is `12`.
* **Applied Price (`InpSourcePrice`):** The source price for the calculation. This unified dropdown menu allows you to select from all standard and Heikin Ashi price types.
* **CMO Period (`InpPeriodCMO`):** The lookback period for the Chande Momentum Oscillator. (Default: `9`).
* **EMA Period (`InpPeriodEMA`):** The base period for the EMA smoothing. (Default: `12`).
* **Applied Price (`InpSourcePrice`):** The source price for the calculation. (Standard or Heikin Ashi).
## 5. Usage and Interpretation
### `VIDYA_Pro` (Single Color)
* **Adaptive Trend Line:** Use it as a more intelligent, responsive trend line. It hugs the price during strong trends and flattens out during consolidation, helping to reduce whipsaws.
* **Trend Filter:** A flat or sideways VIDYA line is a strong indication of a ranging market, suggesting that trend-following strategies should be paused.
* **Dynamic Support/Resistance:** In a trending market, the VIDYA line can act as a dynamic level of support (in an uptrend) or resistance (in a downtrend).
* **Adaptive Trend Line:** Hugs the price during strong trends and flattens out during consolidation.
* **Trend Filter:** A flat or sideways VIDYA line indicates a ranging market.
* **Dynamic Support/Resistance:** Acts as a dynamic level of support/resistance in trending markets.
### `VIDYA_Color_Pro` (Multi-Color)
This version includes all the benefits of the standard `VIDYA_Pro` but adds an immediate visual cue for momentum direction.
* **Trend Direction at a Glance:**
* **Green Line:** Indicates that the underlying momentum is bullish (CMO > 0).
* **Red Line:** Indicates that the underlying momentum is bearish (CMO < 0).
* **Confirmation of Trend Change:** A color change from red to green can act as an early confirmation that bullish momentum is taking over, and vice-versa. This can be particularly useful for timing entries after a pullback. For example, in a larger uptrend, a brief switch to red followed by a return to green can signal a good entry point.
* **Green Line:** Bullish momentum (CMO > 0).
* **Red Line:** Bearish momentum (CMO < 0).
* **Confirmation:** A color change can act as an early confirmation of a trend change.
