When it earns its keep
When this preset earns its keep
Opening-bell momentum. The gapper either breaks above pre-market high (long setup) or flushes to a failed-gap short. Either way, you want the universe pre-filtered before 9:30 ET so you can focus on 3-5 names not 3,000.

The gap-and-go is the canonical opening-bell setup. A stock closes at one price, news hits overnight or pre-market, and the next morning it opens 3% or more above yesterday's close on rising volume. The trade is a two-sided proposition. If pre-market high holds at the open and volume continues to expand, the long setup pays. If the gap fails and the stock flushes back through the prior close, the failed-gap short pays.
Either side requires a filtered universe before 9:30 ET. Out of roughly 8,000 listed US equities, maybe 30 to 80 will gap up more than 3% on any given session, and only 5 to 15 of those will have the volume profile that supports a real trade. Trying to build that watchlist by eyeballing a quote screen is a losing game. The scanner does the filtering so you arrive at the open with a workable list, not a research project.
What we filter on. Gap percent above 3% on the prior close, pre-market volume accelerating versus the 10-day average, price between $1 and $20 for the classic low-float runner band, RVOL above 2x at scan time. The low-float variant tightens to floats under 50 million shares, which is the universe that produces the 50%-plus intraday runners Ross Cameron's Warrior Trading style is built around.
Why the cutoffs. The 3% gap floor strips out drift and overnight noise. The volume filter is what separates a real catalyst from a quiet pre-market print on illiquid paper. Price range matters because gap-and-go behavior is asymmetric across market caps. A $3 stock gapping 8% on volume behaves nothing like SPY gapping 0.4% on the same headline. The setup needs the volatility a sub-$20 name brings.
Common catalysts that fire this scanner: earnings beats, FDA panel decisions, contract awards, M&A rumors, partnership PRs, sector-rotation trades on macro releases. The catalyst tells you whether to expect continuation or a fade. Tapeboard surfaces the headline next to the row so the why is visible without opening another tab.
