Cumulative volume delta (CVD): what it shows, and what it cannot tell you

Every trade has a buyer and a seller, so "more buyers than sellers" cannot be literally true. What can differ is who was in a hurry. Cumulative volume delta, or CVD, counts exactly that: the volume of trades where the buyer hit the seller's price, minus the volume where the seller hit the buyer's price, added up over time. This guide explains how the line is built, how to read it, and what it did and did not tell us in 720 hours of recorded Bitcoin, Ethereum and Solana trades.

How CVD is built, step by step

An exchange keeps a list of waiting orders, the order book. A trade happens when someone sends an order that is filled at once against a waiting order. The side that waits is called the maker. The side that fills at once is called the taker, and the taker is the one who wanted the trade now.

• First, sort every trade. If the taker bought, the trade counts as buy volume. If the taker sold, it counts as sell volume. Crypto exchanges publish this with every trade; Binance, for example, marks for each trade whether the buyer was the maker.
• Then take the difference. Buy volume minus sell volume in a period, for example one minute, is the volume delta of that period.
• Then add it up. The running total of all these differences is the cumulative volume delta.

A small example: in one minute, takers buy 12 Bitcoin and takers sell 9. The delta of that minute is +3. In the next minute, takers buy 5 and sell 11: the delta is −6, and the cumulative line stands at −3.

Two details matter when you compare charts. First, the starting point is arbitrary. A CVD line begins at zero wherever the chart begins, so its level means nothing; its direction and its steepness do. Second, not every chart has trade-by-trade data. Many chart platforms estimate buying and selling from small candles inside each bar. That is an approximation, and two platforms can show different lines for the same market.

How to read a CVD line

• CVD and price rise together. Urgent buyers are pushing the price up. This is the ordinary picture of a rising market.
• CVD and price fall together. Urgent sellers are pushing the price down.
• CVD rises, price does not. Takers are buying, but waiting sell orders absorb them. Traders call this absorption.
• CVD falls, price holds or rises. Takers are selling into waiting buy orders, or the price is moving on another exchange.

The last two cases are called divergences. They are popular in trading videos, and they are also common: in our record below, flow and price pointed in opposite directions in about one hour out of four. A divergence is a reason to look closer. It is not a forecast.

Spot CVD and perpetual futures CVD

In crypto there are two very different markets for the same coin. In the spot market, people exchange dollars for coins. In perpetual futures ("perps"), people take leveraged positions on the price without owning the coin. Each market has its own CVD, and the two often disagree.

The difference matters. Spot buying changes who owns the coins. Futures buying builds leveraged positions that pay funding and can be closed by force when the price turns. A rise carried by spot buyers and a rise carried by leveraged futures buyers look the same on a price chart. On a CVD chart they look different.

The replay shows 3 and 4 November 2026 on Binance. Bitcoin rose 4.8 % over the two days. Net taker buying was about $125 million in the spot market and about $511 million in perpetual futures: four fifths of the push came from leverage. Ethereum looked similar (about $55 million spot, $266 million futures, price up 7.5 %). Solana did not: its spot market saw about $20 million of net buying while its futures saw about $4 million of net selling, and the price still rose 3.8 %.

What 720 hours of recorded trades say

We record every trade in Bitcoin, Ethereum and Solana and store the net taker flow of each hour. For this guide we compared each hour's net flow on Binance (spot and perpetual futures together) with the price change of the same hour and of the next hour. The record covers about 720 hours, from 14 October to 13 November 2026.

Binance, hourly, 14 Oct – 13 Nov 2026	Bitcoin	Ethereum	Solana
Flow and price in the same direction, same hour	75 %	77 %	72 %
Same, only in the quarter of hours with the biggest moves	91 %	93 %	89 %
Correlation of net flow with the price change, same hour	0.77	0.81	0.64
Flow and price in the same direction, next hour	51 %	50 %	49 %
Correlation of net flow with the next hour's price change	0.10	0.06	0.03
Share of net flow that came from perpetual futures	86 %	88 %	82 %
Hours in which spot and futures flow pointed in opposite directions	34 %	32 %	40 %

Three things stand out.

CVD describes the present well. In three hours out of four, the net flow and the price moved the same way, and in the hours with large moves it was about nine out of ten. When the price moves a lot, the CVD almost always shows who pushed it.

CVD did not predict the next hour. Knowing whether takers were net buyers in one hour said almost nothing about the direction of the next: 51 %, 50 % and 49 % are a coin flip. In this record, CVD was a description of the move, not an early warning of the next one.

Futures do most of the talking. More than four fifths of the net flow came from perpetual futures, and in about a third of all hours the spot market and the futures market pointed in opposite directions. A single CVD line that mixes both, or shows only one of them, hides that.

What CVD cannot tell you

• It only sees takers. A large investor who buys patiently with waiting orders appears on the sell side of the CVD, because the people selling to him are the takers.
• It only sees one place. The CVD of one exchange is not the market. Coins trade on many exchanges, in spot and in futures, and large trades are also agreed away from exchanges.
• It does not say why. A futures buy can be a new bet on a higher price, the forced closing of a bet on a lower price, or one half of a hedge. The CVD counts all three the same.
• It is not a forecast. In our hourly record the flow of one hour did not tell the direction of the next.
• Its level is arbitrary. Only the change over a stated period can be compared, never the level of two lines that started at different times.

How to use CVD sensibly

Read it next to the price, not instead of it. Keep spot and futures apart. Compare the same period on more than one exchange before drawing a conclusion. And treat it as a way to understand a move that has happened: who pushed, with cash or with leverage, and how much it took to move the price.
