How the Buyable Gap Up scanner works

Mark Minervini and William O'Neil both treat the buyable gap up as one of the highest-probability entries in growth-stock trading. The setup is simple in concept: a stock gaps up on a catalyst, holds the gap (it never fills back to the prior close), trades above its opening price, and closes in the upper portion of the daily range — all on heavy volume. That combination tells you institutions are accumulating, not selling into the strength. This scanner sweeps 5,000+ stocks for gap ups of 3%+ with at least 1.5x RVOL and $5+ price, then runs the buyability checks: did the gap hold, is the stock above its open, where did it close in the day's range, and is it above its 50 SMA? Each result is graded so the highest-conviction setups float to the top.

What we analyze

Open vs prior close (3% minimum gap up — gap downs excluded)
RVOL — today's volume vs 50-day average (1.5x minimum)
Gap-hold status — did the low stay above the prior close?
Above-open status — is the stock holding near or above its opening price?
Close position in the day's range (closed strong = stronger signal)
Price vs 50 SMA (trend confirmation)
$5 minimum price for institutional quality

How our grading system works

For buyable gap up setups, an A+ grade means a gap of 10%+ that held all day, closed in the upper 30% of the daily range, with RVOL above 3x and price above the 50 SMA. A grades require gap-hold with strong close position and confirming volume. B+ requires the gap to hold with above-average close position. B meets the 3% gap and 1.5x RVOL minimum. This is not a prediction of future price movement — it is a way to prioritize which charts deserve your attention first.

A+
Textbook setup with strong confluence
A
High-quality setup worth watching
B+
