BTC spot CVD chart at 7 p.m. UTC on Sept. 14

Spot CVD is an order-book analysis chart for the BTC/USDT spot trading pair. The upper section shows the volume heatmap, while the lower section represents cumulative volume delta, or CVD. - The upper volume heatmap tracks trading volume at each price level, and 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 lower CVD indicator reflects buy and sell orders by fund size, and the line for each color rises as buy orders increase in that category. The yellow line represents orders between $100 and $1,000, while the brown line is based on large orders between $1 million and $10 million, among others.
