Volume Pairwise Highlight

### Volume Pairwise Highlight

**Overview:**
The "Volume Pairwise Highlight" Pine Script is designed to analyze and visualize the relationship between the volumes of consecutive candlesticks in a trading chart. This script calculates the high-low difference of each candlestick and plots it, while also highlighting specific conditions in the volume histogram.

**Key Features:**

1. **High-Low Difference Calculation:**
- The script calculates the difference between the high and low prices of each candlestick.
- This difference is plotted as a histogram on the main chart for easy visualization.

2. **Volume Condition Highlight:**
- The script checks if the volume of the previous candlestick is higher than the volume of the current candlestick.
- If this condition is met, the current volume bar is highlighted in red; otherwise, it is colored green.
- This helps traders quickly identify periods where there was a drop in volume compared to the previous period.

3. **Volume Display:**
- The volume is plotted as a histogram on a separate pane, making it easy to compare volumes across different periods.
- The coloring of the volume bars provides a quick visual cue for significant changes in trading volume.

4. **Information Display:**
- The script dynamically updates and displays the volume and high-low difference values on the chart.
- This provides traders with immediate feedback on the current trading activity.

5. **Optional Moving Average:**
- The script includes an optional moving average of the high-low difference.
- This moving average can be customized in length and helps smooth out the data for better trend analysis.

**Customization:**
- **Volume Threshold:** Customize the volume threshold to highlight specific volume conditions.
- **Highlight Color:** Adjust the highlight colors to suit your visual preferences.
- **Moving Average Length:** Modify the length of the moving average to better fit your analysis needs.

**Usage:**
This script is useful for traders looking to:
- Identify significant changes in trading volume.
