Woofun AI data shows that the BTC/USDT Spot Cumulative Volume Delta chart on July 1, 2025, tracks buying and selling pressure through a Volume Heatmap and order size categorization. The heatmap identifies high-activity price clusters that may serve as future support or resistance, with brighter zones indicating significant transaction volume.

The CVD indicator distinguishes between retail orders ($100-$1,000, yellow line) and institutional orders ($1M-$10M, brown line). Divergences between these lines signal shifts in market sentiment. Rising large-order CVD during price rallies suggests strong institutional buying, while declining large-order CVD at resistance levels with high heatmap volume may indicate distribution and potential reversal.
