The upper section shows the Volume Heatmap, while the lower section shows cumulative volume delta, or CVD. - The Volume Heatmap tracks trading volume at each price level, and the background color becomes brighter when the price stays in a specific range for an extended period or makes a sharp move. Brighter zones may act as support or resistance. - The CVD indicator in the lower section reflects buy and sell orders by order size, with each colored line rising as buy orders increase. The yellow line represents orders between $100 and $1,000, while the brown line represents large orders between $1 million and $10 million, among other categories.
