Combined Predictive Indicator

### Summary
The **Combined Predictive Indicator** is a comprehensive tool designed to provide traders with a multi-faceted view of potential future price action. It merges several well-known analytical concepts into a single, cohesive indicator, helping to identify key levels of support, resistance, and volatility-based price targets.

This script is an amalgamation of two different concepts:
1. A prediction model based on historical range, ATR, and Fibonacci levels.
2. The "Predictive Ranges" concept, which uses an adaptive ATR-based moving average to project dynamic support and resistance zones.

### Key Components

**1. Original Prediction Model:**
* **Bollinger Bands (BB):** Standard volatility bands that help gauge whether prices are high or low on a relative basis.
* **ATR-Based Predicted Range:** A channel calculated using the Average True Range (ATR) and the average historical bar range. This provides a statistically-based estimate of the potential trading range for the next period. The upper band (green) and lower band (red) represent potential bullish and bearish targets.
* **Fibonacci Levels:** Automatically drawn based on the highest high and lowest low over a user-defined lookback period. These classic 0.382 and 0.618 levels act as potential retracement or target zones.
* **HH/LL Markers:** Small triangles appear above or below the price bars to signal a new Highest High (HH) or Lowest Low (LL) within the lookback period, helping to identify shifts in market structure.

**2. Predictive Ranges (PR):**
* This component calculates five dynamic levels based on an adaptive moving average. When the price moves significantly away from the average, the levels recalculate and project new zones.
* **Resistance Levels (PR Upper 1 & 2):** Red zones that indicate potential areas of selling pressure.
* **Support Levels (PR Lower 1 & 2):** Green zones that indicate potential areas of buying pressure.
* **Average (PR Average):** The blue line serves as the centerline or equilibrium point for the ranges.

**3. Data Table:**
* A convenient table is displayed on the top-right of the chart, showing the real-time values of all key predictive levels. This allows for a quick glance without having to hover over the plotted lines.

### How to Use
* **Confluence is Key:** Look for areas where multiple levels from different components overlap. For example, if the `Predicted Upper Range` aligns with a `PR Upper` resistance level and a `Fibonacci` level, it signifies a strong area of potential resistance.
* **Range Trading:** The `Predicted Range` (gray-filled area) can be used to identify the expected volatility. Prices moving outside this range could signal a strong breakout.
* **Trend Confirmation:** Use the `New HH/LL` markers to confirm trend direction. A series of new higher highs and higher lows suggests an uptrend, and vice-versa.
* **Dynamic S/R:** The `Predictive Ranges` are excellent for identifying dynamic support and resistance in trending or ranging markets. Watch for price reactions as it approaches these zones.

### Settings
* **Original Indicators:** Customize the lengths for Bollinger Bands, ATR, and the HH/LL lookback period. Adjust Fibonacci levels if needed.
* **Predictive Ranges:** Adjust the `Length`, `Factor` (multiplier for ATR), `Timeframe`, and `Source` to fine-tune the sensitivity and responsiveness of the PR levels.
