Earlier and recent activity

What has changed?

The recent comparison uses the last four completed weeks.

Activity centre

Higher

The recent centre moved +15.43% against the earlier part of this period.

Price and volume

No clear disagreement

Price changed -19.07% over four weeks. Volume balance is -39.5% on a scale from โˆ’100% to +100%.

Volume and price movement

More volume, limited price progress

Recent median weekly volume is 1.39ร— the earlier median. This describes price response, not the identity of buyers or sellers.

Recent closes

2 of 4 closes inside

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

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 ยท 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. โ€œStart from a dateโ€ 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.
