BTC spot CVD chart at 7 p.m. UTC on Oct. 20

Spot CVD is an order-book analysis chart for the BTC/USDT spot trading pair. The top panel shows the volume heatmap, while the bottom panel shows cumulative volume delta, or CVD.

- The volume heatmap tracks trading volume at each price level. The background becomes brighter when the price stays in a specific range for an extended period or makes a large move. Brighter areas may act as support or resistance.

- The CVD indicator shows buy and sell orders by order size. As buy orders increase, the corresponding colored line rises. The yellow line reflects orders between $100 and $1,000, while the brown line reflects large orders between $1 million and $10 million.
