BTC spot CVD chart at 7 p.m. UTC on Sept. 18

The spot CVD chart is an order book analysis of the BTC/USDT spot trading pair. The upper panel shows the volume heatmap, while the lower panel shows cumulative volume delta, or CVD. - The volume heatmap tracks trading volume by price range. The background becomes brighter when the price stays in a specific range for an extended period or moves sharply. Brighter zones may act as support or resistance levels. - The CVD indicator shows buy and sell orders by order size. The line for each color rises as buy orders increase in that size band. The yellow line reflects orders between $100 and $1,000, while the brown line reflects large orders between $1 million and $10 million.
