Downward movement can contain evidence of demand
A down bar records a lower close than its open, but its colour does not reveal the full interaction between supply and demand. When heavy selling produces a wide decline yet the bar closes well above its low, lower prices have been rejected within that bar. At an important location, that can be an early observation of strength.
It remains only potential strength until the sequence supports it. A responsive rally, reduced activity on a later reaction, or an inability to revisit the low can strengthen the case. Renewed downside progress on expanding activity would challenge it.
Evidence to inspect on a down bar
Volume
Exceptional activity can show that substantial business occurred, but cannot identify the winning side by itself.
Spread
A wide decline shows movement, while high effort with limited continued downside progress can indicate opposition or absorption.
Close
A close well off the low records rejection. A close near the low records that sellers retained more of the bar's downward result.
Background
Potential strength matters more after a decline or near support than in an arbitrary location, and it still needs a later response.

Read the chart as text and inspect its values
A twelve-bar illustrative decline reaches a wide high-volume down bar that rejects its low, responds upward, reacts on lower activity and then advances.
- Bars 1 through 5 decline with gradually increasing volume.
- Bar 6 has the widest spread and highest volume, reaches the sequence low and closes near its high.
- Bars 7 and 8 respond upward.
- Bars 9 and 10 react on narrower spreads and lower volume.
- Bars 11 and 12 advance, with Bar 12 closing near its high on increased volume.
| Bar | Open | High | Low | Close | Volume |
|---|---|---|---|---|---|
| Bar 1 | 120 | 121 | 116 | 117 | 43 |
| Bar 2 | 117 | 119 | 113 | 114 | 48 |
| Bar 3 | 114 | 116 | 110 | 111 | 54 |
| Bar 4 | 111 | 113 | 106 | 108 | 62 |
| Bar 5 | 108 | 110 | 102 | 104 | 73 |
| Bar 6 | 104 | 106 | 95 | 103 | 100 |

Separate observation from confirmation
1. Record the decline
Bars 1–5 make lower prices while volume rises. Supply is producing continued downside result.
2. Inspect the stopping bar
Bar 6 has the widest spread and highest volume. It reaches a new low but closes near its high, showing substantial rejection within the bar.
3. Look for response
Bars 7–8 close higher. That response supports the idea that demand became effective around Bar 6.
4. Evaluate the next reaction
Bars 9–10 move down with narrower spreads and clearly lower volume than Bar 6. Selling appears less active in this simplified sequence.
5. Demand confirmation
Bars 11–12 advance and Bar 12 closes near its high on increased activity. This confirms current strength within the example, without guaranteeing future direction.
Common mistakes
Treating every down bar as weakness
Inspect whether selling retained the low and whether demand responded afterward.
Buying the first high-volume rejection
A potential sign of strength still requires background, response and risk-defined confirmation.
Ignoring location
Rejection near prior support has different context from the same shape in the middle of a range.
Calling volume demand
Volume is total activity; the price result and later sequence show which side became effective.
Forgetting invalidation
State what renewed supply would make the strength reading no longer reasonable.
Practice: build a strength case
- Describe the trend and volume change through Bars 1–5.
- Measure where Bar 6 closes within its full range.
- List the observations in Bars 7–8 that support demand.
- Compare the volume and spread of Bars 9–10 with Bar 6.
- Write a conditional strength thesis and identify the price behaviour that would invalidate it.
Reflect
- How would the reading change if Bar 6 closed on its low?
- Why is the lower-volume reaction useful but not conclusive on its own?
