On Aug. 18 at 9:00 a.m., the Bitcoin spot market displayed notable order flow activity, as captured by the cumulative volume delta (CVD) chart for the BTC/USDT trading pair. The chart, which tracks the balance between aggressive buying and selling, offers traders a granular view of market pressure at specific price levels.
Understanding the Spot CVD Chart
The spot CVD chart is a tool used by traders to analyze order book dynamics. It consists of two primary components: the volume heatmap in the upper panel and the cumulative volume delta in the lower panel.
The volume heatmap visualizes trading volume at each price level, with brighter colors indicating areas where the price lingered or moved sharply. These zones often act as support or resistance levels, as they represent clusters of historical activity where traders have previously shown interest.
The lower panel’s CVD indicator reflects the net volume of buy and sell orders, segmented by order size. The yellow line tracks orders between $100 and $1,000, while the brown line represents large orders between $1 million and $10 million. When these lines rise, it indicates increasing buying pressure; when they fall, selling pressure dominates.
