Candle Price Movement

This Pine Script indicator calculates and visualizes the price movement for each candlestick on the chart.

- **Calculation**: The price movement for each candle is determined by subtracting the opening price from the closing price.

- **Visualization**: The price movement is plotted as a histogram, with positive values indicating upward movement (green bars) and negative values indicating downward movement (red bars).

- **Options**:
- The histogram bars are colored blue with zero opacity, providing a clear visual distinction from the background.
- A horizontal line at zero (the "Zero Line") is added for reference, helping to identify periods of no price movement.
