Does support survive a longer view?

Advancing-week volume share against price return and closing pressure.

A high advancing-volume share alongside weak closing pressure can mean price rose between closes but finished low within its weekly ranges. The two measures answer different questions.

Effort and result

22% price efficiency

Four-week net price movement as a share of the total close-to-close path. Lower readings indicate more back-and-forth movement, regardless of volume.

Latest close: 45% of the way from the weekly low to high.

Volume-weighted return tilt

-0.74 percentage points

The volume-weighted average weekly return minus the ordinary average over thirteen weeks. Positive means more volume coincided with stronger returns; negative means volume leaned toward weaker returns.

An association within this listing, not measured capital flow.

Price direction30.0 / 30
Closing pressure2.9 / 30
Up-week volume12.3 / 25
Volume confirmation13.3 / 15

Fixed weights favour supported advances. A low score can still contain useful bearish or reversal research.

Test the volume contribution

Did heavier trading change what followed?

Compare high-volume and ordinary-volume weeks with the same price direction.

High volume is at least 1.5× its preceding 26-week median; ordinary volume is 0.75–1.25×. Returns start at that week’s close. Each group uses non-overlapping completed outcomes.

At least eight completed examples in both groups are required. Groups may overlap each other, and differ in volatility, trend and market conditions; their difference is not a causal volume effect or a statistical claim of edge. Up to six years of available history; price returns exclude dividends, costs and execution. Fixed definitions have not been validated out of sample.

Move over the chart, tap a week, or use the arrow keys to inspect it. The profile estimates where volume sits within weekly price ranges. The lower chart accumulates volume weighted by where each week closed in its range; its starting point changes with the selected period. This is not trade-based CVD.

Earlier and recent activity

What has changed?

The recent comparison uses the last four completed weeks.

Activity centre

Higher

The recent centre moved +27.34% against the earlier part of this period.

Price and volume

No clear disagreement

Price changed +5.27% over four weeks. Volume balance is +9.7% on a scale from −100% to +100%.

Volume and price movement

More volume, clear price movement

Recent median weekly volume is 1.49× the earlier median. This describes price response, not the identity of buyers or sellers.

Recent closes

4 of 4 closes above

Price was above the earlier area before these four weeks. The earlier boundaries stay fixed for this comparison.

Activity over time

Darker cells show more estimated volume at that price. Use the chart to see where activity has moved. For longer periods, a column combines several weeks.

Volume and price movement

Each dot is a week. Compare weekly volume with the move from open to close.

What to check next

Holding outside the area

Further closes above the earlier area would show that price is staying outside it. Compare them with the direction of recent volume balance.

Returning inside

A close back inside the earlier area would weaken the move outside it. Check whether the return lasts more than one week.

Price and volume disagreeing

There is no clear disagreement at present. Check whether volume balance continues to support any further price move.

Same stock · Earlier observations

Previous examples

Descriptive history, not a forecast.

Comparisons use the same period length, position relative to the earlier activity area and direction of recent volume balance. Outcomes do not overlap for each following period. At least five examples are needed to show a matched median. The median is the middle result; the all-period median includes earlier periods regardless of their volume reading.

Returns are close-to-close price changes. Interim lows show the lowest price reached during the period. Dividends, fees and trade execution are not included. The available history contains up to six years of weekly observations.

How to read this report

Choose the period

The selected period sets the profile and volume balance starting point. “Start from a date” uses the first available week on or after that date. At least 13 consecutive weeks are required.

Compare earlier activity

The earlier activity area contains most of the estimated volume before the last four weeks. The activity centre is the average estimated price, weighted by volume. Compare subsequent closes with its boundaries, then read the volume balance alongside the price move.

Check the data

Volume is reported for the whole week. The distribution within the range and the direction of pressure are estimates. They cannot identify individual trades, investor holdings or institutional buying.

Reports use saved weekly data and refresh when those records change. Missing or invalid weeks restrict the available periods.
