Earlier and recent activity
What has changed?
The recent comparison uses the last four completed weeks.
Price and volume
No clear disagreement
Price changed -3.23% over four weeks. Volume balance is -22.1% on a scale from −100% to +100%.
Volume and price movement
More volume, clear price movement
Recent median weekly volume is 2.60× the earlier median. This describes price response, not the identity of buyers or sellers.
Recent closes
3 of 4 closes inside
Price was inside 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
Watch which boundary price moves beyond and whether later closes remain outside it.
Returning inside
Price is currently inside the earlier area. Repeated closes here would show that activity remains in the same price range.
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.
| After | Examples | Median change | Sample |
|---|---|---|---|
| 4 weeks | 9 | -1.46 | Available |
| 13 weeks | 3 | — | Too few examples |
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.
