Price Went Up. Did Anyone Actually Buy?
By CryptoTraders · Market Education · 2026-08-20
A green candle tells you price closed higher. It does not tell you whether buyers drove it or sellers simply stepped aside. Those are two different markets, and only one of them keeps going. Cumulative volume delta is how you tell them apart.
What delta actually measures
Every trade has an aggressor. Either a buyer lifts the ask, which is an aggressive buy, or a seller hits the bid, which is an aggressive sell. Delta for a single candle is the aggressive buy volume minus the aggressive sell volume. Cumulative volume delta, or CVD, is the running sum of that delta over time.
When CVD rises alongside price, real takers are paying up to get in. The move has fuel. When price grinds higher but CVD stalls or rolls over, price is drifting on thin participation and passive bids rather than aggressive demand. That gap is the signal.
Divergence and absorption
The classic read is divergence. Price makes a higher high while CVD makes a lower high. Buyers are not confirming the new high, which is a bearish divergence and a common exhaustion tell. The mirror, price making a lower low while CVD makes a higher low, is bullish.
Absorption is the close cousin. Aggressive volume pushes hard, so CVD moves a lot, but price barely budges. That means a large passive limit order is soaking up everything the aggressors throw at it. When the aggressors run out of size, price tends to snap the other way, toward the side that was quietly absorbing.
How to read it yourself
CVD is built into TradingView and shows up on Coinglass, Velo, Aggr.trade, and Bookmap. One caveat trips people up constantly: CVD belongs to a specific venue. A single exchange's delta can mislead you, and spot CVD and perp CVD tell different stories, because spot is real ownership changing hands while a perp is leveraged synthetic exposure that expands and contracts much faster. Read them together rather than trusting one number.
Where the Reversal Scanner fits
Reading delta live across dozens of pairs is a full-time job, and the exhaustion moment is easy to miss if you look away. The Reversal Scanner does the watching for you. It surfaces short-term reversal setups on the 15-minute timeframe, catching the turn at the EMA tap, confirmed by stochastic and candle structure, and posts an annotated dark-theme chart with a confluence score. It does not ask you to read order flow by hand. It tells you when a setup with real structure behind it has formed.
