Features  /  Stock Screener

Quick scans for movers

Only the stocks actually moving, nothing else.

Set a percentile threshold and scan by price change and volume against the 20-day average, across index membership, your own lists, or your positions — no scrolling through what isn't moving.

Quick scans, not a firehose of tickers

Set a percentile threshold and see only the stocks actually moving — by price change and by volume against their own 20-day average — across whatever lists matter to you.

Adjustable percentile threshold

Move the cutoff and watch the list shrink to only the names clearing that bar — no scrolling through hundreds of tickers to find the real movers.

Volume vs. its own 20-day average

A move on 700% of normal volume reads very differently from the same move on light volume — both are shown side by side.

Pre-market and post-market included

Catch a move before the open or after the close, not just during regular hours.

Every list, one screen

Favorites, recent, custom lists, your positions, index membership, and breadth-based groups — switch between them without leaving the page.

Stock screener showing tabs for All, Favorites, Recent, Lists, and Positions, a percentile threshold slider set to the 96th percentile, and a table of tickers grouped by NASDAQ 100, Custom, and Breadth, each with pre/post move, volume vs 20-day average, percent change, and price

Set the bar at the 96th percentile and only the real movers clear it — grouped by whichever list you're scanning.

Built on the lists you already use

The screener isn't one fixed universe — point it at index membership, your own custom lists, your positions, or a breadth-based group, and scan just that slice of the market.

Index & custom lists

Scan the NASDAQ 100, a custom list you built, or any group you've saved — the same percentile logic applies everywhere.

Your positions and favorites

Turn on percentile scanning for just the stocks you hold or watch, so a quick scan doubles as a check-in on your own book.
