Indicator 20

Volume Delta + CVD

Who is actually in control of this session? Delta, cumulative delta and a color engine.

Own pane (plus optional bar coloring) · Intraday, 1m to 1h · Liquid futures, stocks and ETFs

Volume Delta shows buying volume minus selling volume per bar, and cumulative delta adds it up across the session. It answers who is in control right now. When price makes a new high and cumulative delta does not, the move is being sold into.

What it shows

A delta histogram: net buying versus selling volume per bar, from lower-timeframe data.
A cumulative delta (CVD) line, session-anchored or continuous.
A momentum read on the CVD with pressure zones, and an optional engine that tints your chart's candles by that read.

How it reads the market

Price can drift up on no participation; delta shows whether buyers actually paid up. When price makes a new high and the CVD does not, the move is thin. The color engine puts that read on the candles themselves so divergence is visible without staring at the pane.

When to use it, and when not to

It earns its place when

You want to see whether a move has real buying behind it or is drifting on thin volume.
Price and delta diverge, which is the setup this tool exists to find.
You trade intraday and need a participation read between the bars.

Leave it off the chart when

The instrument has poor volume data. Delta built on estimated volume is a guess dressed as data.
You are on a daily chart. Session-level delta is where the information lives.
It is the last minutes before the close. Rebalancing flow distorts delta in ways that mean nothing directionally.

Common questions

What is cumulative volume delta?

The running total of buying volume minus selling volume across the session. Individual bars are noisy; the cumulative line shows which side has been winning since the open.

What does a delta divergence mean?

Price makes a new high but cumulative delta does not follow. The new high was reached on less net buying than the previous one, which usually means it is being sold into. The same logic inverts at lows.

How is delta calculated without order book data?

Trades at the ask count as buying, trades at the bid as selling. Where tick data is not available the split is inferred from the bar's structure, which is an approximation and should be read as one.

Is this the same as on-balance volume?

No. On-balance volume assigns a bar's entire volume to one side based on whether it closed up or down. Delta splits volume within the bar. That difference matters most on the bars you care about, the ones that reverse.
