Volume and Order Flow Trading Rules
Convert market context, participation, aggressive flow, and price confirmation into explicit testable rules.
Core concepts
What to understand
Keep the interpretation direct: participation, aggressive side, and actual price progress.
2
Evidence
Relative volume, VWAP location, delta, CVD, tape, or depth behavior.
3
Confirmation
An observable price action that proves the aggressive side is making progress.

Reading process
Follow the reading steps
Do not jump from one number to a trade. Describe the evidence first.
Define context
State where the setup is valid.
Require participation and flow
Specify measurable thresholds and side.
Require price confirmation
Add entry, invalidation, target, and no-trade conditions.
Knowledge check
Check your interpretation
Select one answer for each question. Feedback appears immediately.
1. Which condition is measurable?
The threshold, baseline, and comparison are explicit.
2. A long rule requires price below VWAP and sustained acceptance above VWAP at the same bar. This is:
The simultaneous conditions cannot both be true under a clear definition.
3. What should order flow confirm?
Flow is evidence about current behavior, not certainty.
4. A long rule uses buying absorbed at the ask as its flow evidence and a close above resistance as its confirmation. What does the validator say?
The lab flags it: ask-side absorption is buying that is not moving price, which conflicts with a long continuation rule that needs the buying to win.
Practical rules
- Avoid contradictory requirements.
- Normalize volume inputs where appropriate.
- Export rules before backtesting them in Backtesting and Trading Systems.
Common mistakes
- Using vague words such as strong or heavy without thresholds.
- Combining multiple versions of the same evidence.
- Optimizing a rule on one chart.
