1
Break
Price crosses a previously defended level.
Lesson · Volume and Order Flow
Volume Confirmation
Evaluate whether volume supports a breakout, continuation, rejection, or failed move.
Core concepts
What to understand
Keep the interpretation direct: participation, aggressive side, and actual price progress.
2
Acceptance
Price closes and continues trading outside the prior area.
3
Failure
Price crosses the level but returns inside, showing the aggressive side could not maintain progress.

Reading process
Follow the reading steps
Do not jump from one number to a trade. Describe the evidence first.
Mark the level
Define resistance, support, or the range boundary before the break.
Check participation
Compare breakout volume with normal volume.
Check acceptance
Require closes, follow-through, or a successful retest outside the level.
Knowledge check
Check your interpretation
Select one answer for each question. Feedback appears immediately.
1. Which is strongest evidence of an upside breakout?
Price must establish acceptance above the level; volume adds participation evidence.
2. Price breaks resistance on high volume, then closes back inside the range. What happened?
Buyers were active but could not maintain higher prices.
3. Does low volume automatically invalidate a breakout?
Low participation weakens confirmation, but price can still establish acceptance.
4. The break bar trades 2,700 contracts; the eighteen bars before it average 1,500. What ratio does the lab report?
2,700 ÷ 1,500 = 1.8, the same arithmetic as RVOL with the baseline drawn from the bars before the break.
Practical rules
- Define the level before the breakout.
- Volume supports a break; acceptance validates it.
- A failed high-volume break can be more informative than a weak break.
Common mistakes
- Buying only because volume is high.
- Moving the breakout level after seeing the result.
- Ignoring a close back inside the range.
