Volume/Price Divergence v2

The "Volume/Price Divergence v2" indicator is designed to analyze the relationship between volume and price movements in a financial market. It helps traders identify potential divergences that may indicate a change in market trends. Here’s a breakdown of how it works:

### Key Components

1. **Volume Calculation**:
- **Buying Volume**: This is calculated based on the relationship between the closing price and the high/low range. If the closing price is closer to the low, more volume is attributed to buying.
- **Selling Volume**: Conversely, if the closing price is closer to the high, more volume is considered selling.

The formulas used are:
```pinescript
buyVolume = high == low ? 0 : volume * (close - low) / (high - low)
sellVolume = high == low ? 0 : volume * (high - close) / (high - low)
```

2. **Plotting Volume**:
- The total volume is plotted in red and buying volume is plotted in teal. This helps visualize the volume distribution during different price movements.

3. **Rate of Change (ROC)**:
- The indicator calculates the rate of change for both volume and price over a specified period. This allows traders to see how volume and price are changing relative to each other.
```pinescript
roc = source / source[length]
roc2 = source2 / source2[length2]
```

4. **Volume/Price Divergence (VPD)**:
- The VPD is derived from the ratio of the ROC of volume to the ROC of price. This ratio helps identify divergences:
- A VPD significantly above 10 may indicate strong divergence, suggesting that price movements are not supported by volume.
- A VPD around 1 indicates that volume and price are moving in harmony.

5. **Horizontal Lines**:
- The indicator includes horizontal lines at levels 10 (high divergence) and 1 (low divergence), serving as visual cues for traders to assess the market's state.

### Interpretation
- **Divergence**: If price makes a new high but volume does not follow (or vice versa), it may signal a potential reversal or weakness in the trend.
- **Volume Trends**: Analyzing the buying vs. selling volume can provide insights into market sentiment, helping traders make informed decisions.
- **Potential for a Strong Move**: A high VPD during a breakout indicates that while volume is increasing, the price isn’t moving significantly, suggesting that a big price move could be imminent.
- **Caution Before Entry**: Traders should be aware that the lack of price movement relative to high volume may signal an impending volatility spike, which could lead to a rapid price change in either direction.

Overall, this indicator is useful for traders looking to gauge the strength of price movements and identify potential reversals or breakouts based on volume trends.
