01 — Overview
Read the delta engine and Volume status first
Auto intrabar attempts lower-timeframe volume delta and falls back to Tick-rule when unavailable. Intrabar CVD, Tick-rule and CLV range-weighted are selectable, but approximate engines do not reconstruct true bid/ask aggressor flow or an order book.
How it works
CVD slope, delta share, CVD Z-score and prior-state persistence form a weighted Pressure Score clamped to -100 through +100. Enter and release thresholds plus hysteresis maintain Positive, Negative and Neutral states. Rolling normalization history continues across resets.
Delta depends on the engine
Intrabar uses official lower-timeframe delta, Tick-rule uses bar direction and recent close change, and CLV weights volume by close location. Fallback is reported in the ledger.
Pressure is a composite score
Slope, delta share, Z-score and prior-state persistence are weighted together. The result is not probability or a trade signal.
Agreement and Effort/Response
Normalized price slope times normalized CVD slope identifies mismatch, while absolute delta versus average volume and price change versus ATR classify effort and response.

CVD Pressure Ledger – Cumulative Volume Delta Flow
Open the public CVD Pressure Ledger – Cumulative Volume Delta Flow page and add it to a TradingView chart. No SG Group account is required.
- Open the “Use on TradingView” link below.
- Select “Use on chart” on TradingView to add the script to your chart.
- Open the gear icon, then Settings → Inputs, and observe the default configuration first.
- Change one input at a time for the symbol and timeframe you are studying.
Prevent misreads when indicators overlap
Overlapping lines, bands, backgrounds or tables can be duplicate drawings of the same kind of information. Never treat visual overlap by itself as stronger evidence or signal agreement. Another CVD, Volume Delta, delta histogram or order-flow-style oscillator can duplicate the CVD line, candles, histogram, zero line, backgrounds and table. The Pressure plot is also rescaled into CVD coordinates and must not be mistaken for another CVD value.
- Start with Clean display or the CVD line and hide any other CVD or Volume Delta study.
- Toggle CVD candles, bar-delta histogram and Pressure Score one at a time to identify each scale and color.
- Read Pressure from the ledger or Data Window, not from its rescaled plot height.
- Keep the ledger clear of another table and do not combine reset tint or Neutral background with another state background.
03 — How to read it
A practical reading order
Do not turn one value or color into a conclusion. Check the condition, persistence and relationship to price in order.
Check Engine and Volume
Read Intrabar, Tick-rule, CLV or Auto->Tick together with Available or Unavailable / flat CVD before interpreting flow.
Read the true Pressure value in the table
The plotted Pressure line is rescaled into the CVD range. Use the ledger or Data Window for the actual -100 to +100 value.
Separate State, Agreement and Effort
Positive/Negative/Neutral, price-flow mismatch and High effort / muted response are related but different descriptions, not one trade direction.

05 — Alerts
Alerts report events, not decisions
Alerts are state, touch or transition events defined in the public source. They are not trade instructions.
- Pressure state changed, Positive pressure state started, Negative pressure state started and Pressure returned to neutral.
- New positive CVD extreme and New negative CVD extreme.
- Price-flow mismatch started and Price-flow mismatch expanded.
- High effort / muted response context, Reset period started and Data fallback active.
06 — Limitations and responsible use
Not a buy/sell signal
This tool is for analysis and visualization. It is not investment advice, a trade recommendation, a forecast, or a promise of profit or accuracy. Results depend on inputs, symbol, timeframe, and data feed. You remain responsible for every trading decision.
Not true order flow
Tick-rule and CLV are bar-based estimates. They do not reconstruct bid/ask trades, a footprint, an order book or true aggressor side.
Intrabar availability varies
Lower-timeframe history and precision depend on symbol, exchange, feed, TradingView plan and selected LTF. Auto can fall back.
Volume and realtime constraints
FX or CFD feeds may use tick volume; absent volume can leave CVD flat. Plots can update until the realtime bar closes.
Important
Bar delta, CVD, Pressure, Agreement and Fingerprint derive from the same price and volume series. Do not count them as independent signals. Positive or mismatch does not provide an entry, exit, target or stop.
07 — FAQ
Frequently asked questions
Clarify delta engines, fallback, Pressure scaling and volume constraints.
Is CVD Pressure Ledger – Cumulative Volume Delta Flow free to use?
Yes. It is a free, open-source indicator published by SG Group on TradingView. Review TradingView’s terms and the conditions attached to the public script before reuse or redistribution.
Should I change the settings immediately?
Start with the published defaults and observe the drawings and state changes first. Then change one input at a time for the symbol, timeframe and data feed so you can identify what caused each visual change.
Can I display it with other indicators?
Yes, but similar lines, bands, backgrounds and tables can overlap and obscure their source. Isolate each indicator first and hide duplicate components. Visual overlap alone is not stronger evidence or signal agreement.
Does the display provide trade signals?
No. It is analysis and visualization context consistent with the public description. It does not provide entries, exits, targets, stops, price forecasts, or promises of profit, win rate or accuracy.
Does the plotted Pressure line directly use the -100 to +100 scale?
No. It is rescaled into the recent CVD range for display. Read the actual score in the ledger or Data Window.
Source basis and update policy
