/**
 * Volume Delta Indicator
 *
 * Approximates up/down volume by comparing close to open price.
 * When close > open, volume is considered buying pressure (up volume).
 * When close < open, volume is considered selling pressure (down volume).
 * Delta = upVolume - downVolume
 *
 * PineScript display:
 *   hline(0)
 *   plotcandle(openVolume, maxVolume, minVolume, lastVolume, "Volume Delta", color=col, bordercolor=col, wickcolor=col)
 *
 * Note: TradingView's version uses intrabar data for more precise calculation.
 * This implementation uses close vs open as an approximation.
