Find stocks gapping 5%+ from the previous close. Gap scanner identifies catalyst-driven moves with volume confirmation and gap-fill analysis across 5,000+ stocks.
A 5%+ overnight gap is rarely random — it almost always means a catalyst. Earnings beats and misses, FDA decisions, M&A announcements, analyst upgrades and downgrades, sector rotations, and breaking news all show up first as gaps. This scanner sweeps 5,000+ stocks for names that opened more than 5% above or below the prior close, then enriches each result with two things day traders actually need: gap-hold status (did the gap fill, or did it stick?) and volume context (RVOL plus absolute share volume). A gap that holds on heavy volume is a continuation setup. A gap that fills back in is a fade setup. Either way, you want to be looking at it.
For 5% gap setups, an A+ grade means a gap of 20%+ that held completely (never filled), with RVOL above 5x and absolute volume above 5M shares. A grades require 10%+ gaps with strong volume. B+ requires the gap to hold with 2x+ RVOL. B meets the 5% gap minimum. This is not a prediction of future price movement — it is a way to prioritize which charts deserve your attention first.
