CVD - Cumulative Volume Delta
Whether buyers or sellers are being the aggressive side.
Overview
Every trade has a buyer and a seller, so total volume alone cannot tell you which side was in control. Cumulative Volume Delta answers a narrower question: which side was impatient.
- Data Type: Order flow derivative
- Primary Use: Confirming or questioning a price move
- Best Timeframes: All, most useful intraday
Market Orders vs Limit Orders
To understand CVD you first need the distinction between the two ways to trade.
- Limit order: You post a price and wait. You are providing liquidity, and you are patient.
- Market order: You take whatever price is available now. You are removing liquidity, and you are aggressive.
Delta counts only the aggressive side. When a market buy hits a resting sell order, that volume is counted as positive. When a market sell hits a resting buy, it is counted as negative.
How CVD Is Built
Delta for one candle is aggressive buying minus aggressive selling. CVD is simply that figure added up over time, producing a running line you can compare against price.
A rising CVD means aggressive buyers have been dominant. A falling CVD means aggressive sellers have been.
Reading CVD Against Price
CVD is most useful when it disagrees with price. Four combinations are worth knowing.
Price Up, CVD Up
Healthy. Buyers are lifting offers and price is responding. The move is supported by genuine aggression.
Price Up, CVD Flat or Down
Price is rising without aggressive buying. This usually means sellers have simply stopped offering, so it takes little effort to lift price. Such moves can be fragile, because nothing was actually bought with conviction.
Price Down, CVD Down
Healthy downside. Sellers are hitting bids and price is falling accordingly.
Price Down, CVD Flat or Up
Aggressive buying is occurring but price is still falling, which means large passive sellers are absorbing it. This absorption often appears near the end of a move, but it can also continue for a long time.
Absorption
Absorption is the key concept. When CVD moves strongly but price does not, someone large is sitting on the other side using limit orders. That participant is patient and well capitalised, and when they stop absorbing, price usually moves quickly in their direction.
Psychology Behind CVD
Aggression signals urgency. Traders who use market orders are willing to pay a worse price to be filled immediately, which typically means fear or fear of missing out. CVD lets you see which emotion is currently paying up.
Confirmation Signals
- CVD divergence occurring at a significant support or resistance level
- Absorption visible on high volume with little price movement
- CVD trend agreeing with the higher-timeframe price trend
- Consistency across major exchanges rather than a single venue
Weaknesses & Limitations
- CVD is exchange-specific, and crypto liquidity is spread across many venues
- Spot and perpetual CVD often disagree, and both can be valid
- Divergences can persist far longer than a position can survive
- Not all platforms calculate it identically
- It says nothing about size held, only about aggression
Example Use
Price grinds to a new high but CVD makes a clearly lower high, showing the push was not driven by aggressive buying. A trader already long uses this as a reason to take partial profit, rather than as a reason to enter a short.
Risk Management Notes
CVD describes what has happened, not what must happen next. Absorption can continue for a long time before it resolves, and a divergence is not a timing signal. Treat it as a reason to adjust conviction and size, never as a standalone entry.
