Volume Heatmap Candles

This indicator colors each candle based on its relative volume, using a user-defined color gradient for up bars and down bars. Higher-volume candles are shown in deeper shades, while low-volume candles appear lighter. This creates an immediate visual heatmap of market participation, helping traders quickly spot strong moves, weak moves, breakouts, and volume spikes—directly on the price chart without needing to check the volume panel.
