Volume Delta

Both tools come from footprint buy vs sell volume. They need a footprint-capable symbol. They also need a fixed bar duration, so they are unavailable on monthly timeframes. Add them from Indicators → Orderflow.

Volume Delta

Per-bar buy volume − sell volume as columns in a new pane. Green when buyers lifted more; red when sellers hit more.

Mode switches what the delta measures:

• Total (default): total buy volume minus total sell volume (who traded more).
• Average: average trade size per side (volume ÷ trade count): who traded larger. A rising average-mode delta with a flat total-mode delta means fewer but bigger buyers.

Average mode needs per-side trade counts; bars without them leave an honest gap instead of plotting zero.

Cumulative Volume Delta

CVD is the running sum of the per-bar delta, in its own pane. Reading it answers whether pressure is accumulating: price making highs while CVD makes lower highs is the classic absorption divergence.

• Style: Candles (default, with true intra-bar wicks showing how far delta swung inside each bar), Line, or Area.
• Anchor: where the running sum resets, in UTC periods: Day, Week, Month (default), or All data.
• Mode: Total or Average, same semantics as Volume Delta.

Use Volume Delta to read each bar; use CVD to see whether that pressure is accumulating across the session.
