Trade-Based CVD vs Candle-Based CVD: Why Results Differ

Two CVD lines on the same market can trend in opposite directions. The method behind each, trades or candles, usually explains why.

Short answer

Trade-based CVD sums each trade's volume signed by its taker side. Candle-based CVD, like TradingView's, signs each lower-timeframe bar's whole volume by whether the bar closed up or down. They agree when sub-bars are one-directional and disagree when buying and selling mix inside sub-bars, which is common in fast, choppy markets. Precision of candle-based CVD also falls on older history as coarser bars are used.

Two methods

How each CVD is builtHow each CVD is built. Left, Candle-based: Signs whole sub-bar volume; Up close = +, down close = −; Coarser on older history; Works without trade data. Right, Trade-based: Signs each trade by taker side; Exact aggressor split; Needs trade data; Same precision while trades exist.CANDLE-BASEDSigns whole sub-bar volumeUp close = +, down close = −Coarser on older historyWorks without trade dataTRADE-BASEDSigns each trade by taker sideExact aggressor splitNeeds trade dataSame precision while trades exist

Worked example

Illustrative 1-minute sub-bar: 40 BTC of aggressive sells, then 25 BTC of aggressive buys that lift the close 1 tick above the open.

Delta for that minute (BTC)Delta for that minute (BTC): Candle-based +65 BTC; Trade-based -15 BTC.DELTA FOR THAT MINUTE (BTC)Candle-based+65 BTCTrade-based-15 BTCCandle-based assigns all 65 BTC to buying because the bar closed up; trade-based nets −40 + 25.

Choosing which CVD to use

If you trade one crypto venue and need to know who aggressed at each moment, prefer trade-based delta on that venue. If you need a quick view across many assets, including non-crypto markets, candle-based CVD on a general platform is convenient and good enough for broad direction.

Whichever you use, label it. A screenshot captioned 'CVD rising' says little; 'trade-based CVD, venue A perp, reset 00:00 UTC, rising' can be checked and compared by someone else.

If two traders disagree about what CVD showed, the first question is which method each used. Often both are right about their own line.

Questions readers ask

Why do two CVDs disagree?

Different methods, intrabar timeframes, venues or resets.

Which is more accurate?

Trade-based measures aggressor side directly; candle-based is an estimate.

Is candle-based CVD useless?

No; it is useful for broad context, especially when trade data is unavailable.
