📊 Volume Split Buy/Sell | Copytrade Tungdubai

This Pine Script calculates the estimated buy and sell volume based on price action (relative position of the close within the price range of the candle) and plots the values on the chart. Additionally, it detects significant volume spikes by comparing the current volume to a 20-period moving average of volume.

Here’s a breakdown of what each section of the script does:

1. **Inputs and Variables:**
- `vol`: This variable holds the volume of the current candle.
- `body`: This calculates the absolute difference between the close and open prices (i.e., the body size of the candle).
- `price_range`: This is the range between the high and low of the candle.
- `buy_ratio`: This is the ratio of the candle's body above the close relative to the total range, representing buying pressure.
- `sell_ratio`: This is the inverse of `buy_ratio`, representing selling pressure.

2. **Volume Calculation:**
- `buy_volume`: The estimated buying volume is calculated as the total volume multiplied by the buying ratio.
- `sell_volume`: The estimated selling volume is calculated as the total volume multiplied by the selling ratio.

3. **Volume Plots:**
- The script plots the estimated selling volume in red below the baseline (`sell_volume`).
- The estimated buying volume is plotted in lime above the baseline (`buy_volume`).

4. **Volume Spike Detection:**
- `vol_ma`: This is the 20-period simple moving average of volume.
- `vol_spike`: This condition checks if the current volume is greater than 2.5 times the 20-period moving average of volume.
- If a volume spike is detected, a tiny purple circle is plotted at the bottom of the volume bar.

This script can be useful for visualizing the relative strength of buy and sell volumes, as well as detecting unusual volume spikes that might signal significant market activity.
