Pre-Market Movers Scanner
The opening bell universe starts forming at 4am ET. Earnings, FDA news, partnership announcements, macro-catalyst reactions — all show up in pre-market trade. This scanner surfaces the names with real pre-market activity (not just one halted print) so you're watching 5-10 tickers at 9:29, not 500.
§01 // TRIGGERS_FOR_PRE_MARKET_MOVERS
Triggers for pre-market movers
- Pre-market price change > 2% (configurable)
- Pre-market volume > 50K shares (configurable — filters single-print noise)
- News / earnings flag where available
- Sorted by pre-market RVOL for biggest anomalies first

The trading day starts at 4 AM ET, not 9:30. Earnings drop after the closing bell, FDA news prints overnight, partnership announcements hit before sunrise, and macro reactions to international sessions show up in pre-market trade hours before retail brokerages even open. The pre-market movers scanner is the tool that compresses that overnight news flow into a single watchlist instead of four browser tabs and a Twitter feed.
What we filter on. Pre-market price change above 2% with configurable threshold, pre-market volume above 50,000 shares to filter out single-print noise, sorted by pre-market RVOL so the biggest anomalies surface first. News and earnings flags layer on top where the data is available. The 50,000-share floor is what separates a real pre-market mover from a stock with one thinly-traded print at a wide spread.
Why pre-market matters. Two reasons. First, the catalyst-to-price reaction window is most informative in pre-market because volume is thin and the tape is reactive. A stock that gaps 8% on 200,000 shares of pre-market volume tells you exactly how the market is reading the catalyst. Second, pre-market action sets the stage for the opening bell. The gap-and-go setup, the failed-gap short, the morning-reversal trade all key off pre-market price levels.
How traders use this. Run the scanner at 7 AM ET to see what gapped overnight. Re-run at 9 AM ET to catch names that started moving on the European session reaction. Cross-check against the gap-and-go scanner to identify names that satisfy both criteria. Names that show up in both feeds are higher-conviction opening-bell setups.
Common pre-market catalysts: earnings released after-hours the prior session, overnight FDA panel decisions, geopolitical headlines that hit during Tokyo or London hours, macro releases scheduled for 8:30 ET that move sector ETFs in pre-market, M&A leaks, and crypto-sector news that breaks 24/7.
Pre-market is also where overnight Blue Ocean ATS prints get promoted into the standard pre-market session at 4 AM. Tapeboard runs a dedicated bridge for that handoff so the tape stays continuous.
