Nexus ScreenerPre-market scanner for day traders
Find the stocks gapping before the 9:30 AM ET open. Nexus Screener scans the whole market from 4:00 AM ET and ranks every gapper by its move from yesterday’s close, with the numbers you check before the bell.
What it finds
- Every stock gapping up from 4:00 AM ET, ranked by gap %
- Pre-market volume, high and low (PMH / PML), and relative volume
- Free float, so you can spot low-float gappers at a glance
- Today’s company news and SEC filings behind each move
- Earnings due today and trading halts, in the same Morning Brief
How to set it up
- Open the Morning Brief tab before the open: gappers are ranked from 4:00 AM ET.
- Or use the scanner’s Up 10% Today preset and sort by % change while it’s still pre-market.
- Narrow it in Filters: Gap %, at least, a float limit (for example under 20M) or Relative volume, at least.
- Tap a stock for its chart with pre-market high and low, VWAP and the news.

The scanner, presets, filters, charts and the Morning Brief are free. Nexus Pro adds push alerts, saved scans, “why it’s moving” news on every stock, the Supernova scorecard and the dilution risk score, with a 7-day free trial. See pricing.
Questions
When does the pre-market scanner start?
At 4:00 AM ET, when pre-market trading begins. The overnight data resets around 3:30–4:00 AM ET, so the first gappers appear as soon as stocks start trading.
Is the pre-market scanner free?
Yes. The Morning Brief and the scanner are free. Nexus Pro adds a 9:00 AM ET pre-market push alert with the top gappers and your watchlist’s news.
What is a good pre-market gap for day trading?
There’s no single number. Many momentum traders look at stocks up 10% or more with heavy pre-market volume and a clear catalyst, but every gap can fade.
