BTC spot CVD chart at 7:00 p.m. UTC on Aug. 17

The spot CVD chart analyzes the BTC/USDT spot pair order book, with the upper section showing a volume heatmap and the lower section showing 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 makes a large move, and brighter zones may act as support or resistance. - The CVD indicator shows buy and sell orders by capital size. As buy orders increase, the line in the corresponding color rises. The yellow line represents orders between $100 and $1,000, while the brown line represents large orders between $1 million and $10 million.
