Stock Volume Tool

Big Volume Day, now what?

The Stock Volume tool reads today's volume multiplier, and fires when it detects higher than usual volume activity.

Volume is the conviction behind a move. A stock that climbs 2% on a quiet tape is a different animal from one that climbs 2% on triple its usual turnover, the second one had real money behind it, and big institutions leave footprints in the volume long before they leave them in the headlines.

But a single big-volume day is ambiguous on its own. Heavy buying can mean a trend is being born, or that the last buyers are piling in at the top. Heavy selling can mean capitulation, or the start of a slide. The only way to settle it for a particular stock is to look at what the price did the last times the stock printed similar high-volume numbers.

What the Tool Shows You

A live volume read, a 45-day forward price cone, a Chance of Move bar graph, a full sortable event log, and a watchlist scan of today's highest-conviction volume days.

Signal

Live Volume Read

One glance tells you whether today is a quiet drift or an unusually heavy print.

Headline

45-Day Projected Price Cone

Projects the next 45 days by applying forward returns from past similar volume days.

Probability

Probability Graph

How often price rose or fell by a set percentage after similar volume days.

Metric

The Volume Multiplier

Today's volume divided by the trailing 30-day average. A multiplier of 2.0 means today traded twice its recent average volume.

Scan

Auto-Detection

The tool scans the market and auto-highlights stocks with unusual daily volume.

Log

Historical Log

The Historical Log displays every past instance when price showed similar unusual activity.

How Traders are using the Volume Detection Tool

1

Spot the unusual volume day

Check if any stocks on your watchlist or in the market had unusual volume days.

2

Check the projected price

Open the 45-day price cone. It shows how price behaved after similar high-volume conviction days in the past. This gives you a realistic view of what typically happens next instead of guessing.

3

Size the move with the bar graph

Switch to Bar Graph view and set your target price level. The bars show how often similar volume days reached that distance by upcoming expirations. Toggle between "By Touch" and "By Close" depending on your strategy.

4

Review the events log for context

Before acting on the signal, open the events log. Check how many historical matches exist and whether they cluster in one period. A small sample or regime-specific cluster tells you the signal may be less reliable than the percentages suggest.
