Chapter 10 — Cumulative Volume Delta (CVD)
Green/red: bar delta · Blue: running sum from zero
HYPOTHETICAL LEARNING DIAGRAM · NOT LIVE DATAWhat is this concept?
CVD sums classified trade delta from a specified reset point. Session resets, venues, missing ticks and classification methods can produce different curves.
Daily learning workflow
1. Identify the instrument, venue and observation interval. 2. Read the chapter definition and reproduce its worked calculation. 3. Watch the supporting workshop and compare its platform conventions with your data. 4. Write the reset time and calculate a ten-bar sequence. 5. Record what happened, what you inferred and what would invalidate your interpretation.
Evidence and interpretation
Keep three separate notes: observed transactions or book changes; your explanation of those observations; and a paper rule with a defined failure condition. Compare at least one counterexample. Do not turn an illustration into a live claim.
Worked example
Hypothetical worked example: Bar deltas +120, −80 and +60 yield cumulative values 120, 40 and 100 from zero.
Common mistakes and limits
Do not treat this observation as a guaranteed signal. Check the venue, data classification, session boundaries and costs. A candle or aggregated order book does not reveal the identity or total holdings of traders.
Practice
Write the reset time and calculate a ten-bar sequence. Use recorded or paper data. Log the observation before revealing the outcome.
