// DESCRIPTION:
// This script calculates and displays various volume-related metrics in real-time
// to help traders analyze buying and selling pressure in the market. It includes
// features such as volume delta, cumulative delta, volume delta pace, and price-volume
// delta relationship. This script also highlights High Volume Nodes (HVNs) and Low
// Volume Nodes (LVNs) and allows users to customize various display options.

// USAGE:
// 1. Add this script to your TradingView chart by copying and pasting the code into
// a new Pine Script indicator.
// 2. Customize the input parameters to suit your analysis needs:
// - Timeframe: Select the timeframe for analysis.
// - Mode: Choose between "Up/Down/Neutral" or "Up/Down" to consider neutral volume.
// - Show Split: Display the split of buy, sell, and neutral volumes separately.
// - Show Start Line: Display a line indicating where real-time data starts.
// - Show MA: Display a moving average of volume.
// - MA Period: Set the period for the volume moving average.
// - Show Net Delta Vol Above Bar: Display the net delta volume above the bar.
// - Show Cumulative Delta: Display the cumulative delta volume.
// - Scale Down Factor: Scale down the net delta value for better readability.
// - Highlight Threshold: Highlight bars based on a threshold of average volume.
// - Show Buying/Selling Pressure in Candlestick: Show buying and selling pressure
// directly in the candlestick.
// - HVN Threshold: Set the threshold for High Volume Nodes based on average volume.
// - LVN Threshold: Set the threshold for Low Volume Nodes based on average volume.
// 3. Interpret the volume metrics displayed in the table and on the chart to make
// informed trading decisions.

// HELPFUL TIPS:
// - Use the "Volume Delta" metric to gauge the difference between buying and selling
// pressure in real-time.
// - The "Cumulative Delta" helps track the overall buying or selling pressure over time.
// - "Delta Pace" indicates the speed at which volume delta changes, which can signal
// strong buying or selling pressure.
// - Analyze the "Price-Delta Relationship" to understand potential reversals or trend
// continuations. For instance, if the price is rising but delta is falling, it could
// suggest weakening buying pressure and a potential reversal.
// - Pay attention to HVNs and LVNs, as they can indicate significant support or resistance
// levels based on volume concentration.
