Expected Relative Volume Stock Screener
Screen rolling volume against session expectations in ChartsWatcher. Compare 1-, 5- or 15-minute activity with a baseline from the prior 15 trading days.
Understand the metric
What is Expected relative volume (%)?
Expected relative volume compares rolling 1-minute, 5-minute or 15-minute volume with expected average session volume for the matching interval, using the previous 15 trading days. Its reference is historical session activity, rather than the last 15 candles. It also differs from same-time relative volume, which describes cumulative activity up to the current point in the session.
An illustrative example
Expected relative volume (%) in practice
If the expected 5-minute session volume is 40,000 shares and the rolling 5-minute volume is 80,000, activity is 200% of that expectation. The example compares an interval with its expected activity; it does not say that the entire day has traded twice its usual cumulative volume.
Make it part of your workflow
A more deliberate stock screen.
Use this ChartsWatcher filter to locate short windows of activity that stand out against historical session expectations. Combine it with absolute volume to distinguish percentage intensity from share count, then inspect the chart for the timing and price behavior within the active interval.
ChartsWatcher lets you combine this filter with other criteria in a toplist and rank the results by the columns you care about. Keep the shortlist beside charts, stock news, and watchlists in your own layout.

How do I add Expected relative volume (%) in ChartsWatcher?
Open or create a toplist and add Expected relative volume (%) to its filter configuration. Choose the available options and the bounds that fit your screen. Combine it with other metrics to narrow the results. Filters can also refine which stocks qualify for an alert.
What should I check when interpreting this filter?
The baseline is derived from previous sessions and may not describe unusual event days well. Do not interchange this measure with a recent-candle or cumulative same-time volume ratio.
From an idea to your own scan.
Use Expected relative volume (%) with the other conditions that define your setup. Keep matching stocks, charts, and news together, with a configuration you can refine as you go.
